The Use of Chlormequat Chloride on Various Crops

1. The removal of seed “eating heat” injury

Rice: When the temperature of rice seed exceeds 40℃ for more than 12h, wash it with clean water first, and then soak the seed with 250mg/L medicinal solution for 48h, and the medicinal solution is the degree of drowning the seed. After cleaning the liquid medicine, germinate below 30℃, which can partially relieve the damage of “eating heat”.

2. Cultivate strong seedlings

Wheat:Soak the seeds with o.3% ~ 0.5% liquid for 6h, the liquid: sed-1: o.8, dry sowing, spray the seeds with 2% ~ 3% liquid, and sow the seeds for 12h, which can make the seedlings strong, developed roots, more tillers, and increase the yield by about 12%. Spraying with 0.15%-0.25% liquid at the early stage of tillering, spraying liquid 50kg/667m2 (the concentration should not be higher, otherwise it will delay the earing and ripening), can make wheat seedlings short and healthy, increase the tillering, and increase the yield by 6.7%-20.1%.

Corn:Soak the seeds with 50% water l] dilution 80 ~ 100 times for 6h, the appropriate solution to drown the seeds, dry after sowing, can make the plants short and strong, developed roots, low rod formation, no bald head, large ear full grain, yield significantly. Seedling with o.2% ~ 0.3% liquid medicine, every 667m2 spray 50kg, can play a role in squat seedling, and resistant to salt alkali and drought, increase about 20%.

3. Inhibit stem and leaf growth, resist lodging and increase yield

Wheat

Spraying at the beginning of the jointing of the end of tillers can effectively inhibit the elongation of the lower part of the stalk between 1 and 3 nodes, which is very beneficial to prevent lodging of wheat and improve the heading rate. If 1000 ~ 2000mg/L of liquid medicine is sprayed at jointing stage, it will not only inhibit internode elongation, but also affect the normal development of ear, resulting in yield reduction.

Rice

In the early stage of rice jointing, spraying 50 ~ 100g of 50% water and 50kg of water with stems and leaves every 667m2 can make plants short and strong, prevent lodging and increase yield.

Corn

Spraying 30 ~ 50kg/667m2 with 1000 ~ 3000mg/L liquid on the leaf surface 3 ~ 5d before jointing can shorten the internode, reduce ear level, resist falling, shorten the leaf width, enhance photosynthesis, reduce balding, increase the 1000-grain weight, and finally achieve yield increase.

Sorghum

Soak seeds with 25-40mg /L liquid for 12h, liquid: seeds 1:0.8, dry and sow, can make plants short and strong, yield significantly. About 35d after seeding with 500 ~ 2000mg/L of liquid medicine, spray 50kg of liquid medicine every 667m2, can make plants dwarfed, stem thick, dark green leaf color, leaf thickening, anti-fall, spike weight, 1000-grain weight increase, yield increase.

Barley

When 0.2% liquid was applied to barley base internode elongation, spraying 50kg liquid every 667m2 could reduce plant height by about 10cm, increase stem wall thickness and increase yield by about 10%.

Sugar Cane

The whole plant was sprayed with 1000-2500mg /L liquid 42d before harvest, which could dwarf the whole plant and increase the sugar content.

Cotton

Spraying the whole plant with 30-50mL/L liquid at the first flowering stage and the second at the full flowering stage can play a dwarfing, topping and increasing effect.

Soybeans

Sowing soybean seeds in the shade after wrinkling skin can play a role in dwarfing, promoting branching, increasing pod number and so on. At the beginning of flowering, 100-200mg /L of liquid medicine, 50kg sprayed every 667m2, can dwarf, promote branching and increase pod number. In flowering, 1000-2500mg /L of liquid medicine was used to spray leaves, dwarfizing plants, strengthening stalks, preventing lodging, increasing branches, increasing pod number and seed number, and increasing yield. At flowering stage, spraying the leaves with 1000-2500mg /L liquid medicine, 50kg per main, can inhibit the barren growth, make the stalk thick, reduce the fur grain, increase the grain weight, and increase the yield by 13.6%, but the use concentration should not exceed 2500mg/L.

Sesame

In the true leaf stage, 30mg/L liquid was sprayed twice (7d interval), which could reduce plant height, reduce the initial capsule part, lower feet and thick stems, resist lodging, shorten the nodes and dense capsules, increase the number of capsules and grain weight, and increase the yield by about 15%. Spraying the whole plant with 60 ~ 100mg/L liquid medicine before final flowering can increase chlorophyll content and photosynthesis, promote nitrogen metabolism and protein increase.

Cucumber

When 3 to 4 true leaves are opened, 100 to 500mg/L of liquid medicine can be sprayed on the leaf surface to dwarf the plant. When 14 to 15 leaves are opened, spraying with 50 to 100mg/L of liquid medicine can promote fruit setting and increase yield.

Melon

Spraying seedlings with 100-500mg /L liquid medicine can strengthen seedlings, control growth, resist drought and cold, and increase yield. Zucchini was sprayed with 100 ~ 500mg/L liquid medicine to control the length, drought resistance, cold resistance and increase production.

Tomato

At the beginning of flowering, 500-1000mg/L of liquid medicine is used to spray the leaf surface, which can control the flowering length, promote reproductive growth, improve fruit setting rate, and improve yield and quality.

Pepper

For pepper with a tendency of barren growth, 20 ~ 25mg/L of liquid medicine at the initial flowering can inhibit the growth of stems and leaves, make sandalwood dwarf and thick, dark green leaves, and enhance the ability of cold resistance and drought resistance. Spray 100 ~ 125mg/L of Aizhuangsu in flowering period can produce more fruit, promote early ripening, increase yield, and improve the ability of resistance to bacterial wilt.

Wenzhou honey orange

During the occurrence of summer shoot, spraying with 2000-4000mg /L荮 or pouring with 500-1000mg /L medicinal solution can inhibit summer shoot, shorten branches, increase fruit setting rate by more than 6%, and the fruit color is orange-red, shiny, bright and attractive. Increase the value of goods and increase production by 10%-40%.

Apples and pears

After harvesting, spraying with L000-3000mg /L liquid medicine on the leaf surface can inhibit the growth of autumn shoots, promote the formation of flower buds, increase fruit setting in the next year, and improve stress resistance.

Peach

Before July, spray new shoots 1-3 times with 2000-3000 times solution of 69.3% dwarf hormone, which can inhibit the elongation of new shoots, and promote leaf maturation and flower bud differentiation after new shoots stop growing. Generally, flower bud differentiation is completed 30-45 days after shoot stop growing.
The spraying of lemons can promote flower bud differentiation, improve the fruit rate and cold resistance in the following year, and make the winter normal leaf fall. The time is from late October to early November. Before normal harvesting, the spraying of 1000mg/kg+ 10mg/kg gibberellin in the crown can inhibit the growth of fruits, and extend the harvesting to late spring of the next year, and produce small fruits and high-quality fruits.

Pear

4-6 years old and long flowering trees, after blooming, spray the concentration of 500mg/kg, spray twice (2 weeks apart), or spray 1000mg/kg liquid once, can control the growth of new shoots, improve the flower amount and fruit setting rate in the second year.
When the new shoots grew to 15cm (late May to early June), spraying 3000mg/kg of liquid medicine inhibited the growth of new shoots and increased the number of flower buds, which significantly improved the fruit quality.

Jujube

The growth of jujube head could be controlled effectively and the fruit setting rate was more than 2 times higher than that of the control when 8 to 9 leaves were sprayed before flowering. Spray twice before flowering and 15 days after secondary application with a concentration of 2500-3000mg /L, such as rhizosphere watering, each plant with 1500mg/L of 2.5L or 500mg/kg of water, can play the same effect.

Jujube dwarf hormone + anti-cracking, in the jujube fruit into the growth period before ripening (around August 10) the whole tree spraying, spraying once every 7 days, spraying 3 times, the cracking rate reduced by 20%.

Grapes

When the shoots grew to 15-40cm, spraying 500mg/kg of liquid medicine could promote the differentiation of winter buds on the main vine. Spray 300mg/kg of liquid medicine in the first 2 weeks of flowering or 1000-2000mg /kg in the rapid growth period of secondary shoot, promote the bud differentiation into flower buds, compact ear, beautiful fruit, improve quality and yield; At the beginning of the growth of new shoots and before flowering, use the pyrrosia, little white rose, Riesling and other varieties, spray with 100-400mg/L pyrrosia solution; Spray the Jufeng grape with 500-800mg/L of the dwarf hormone solution. (Note: The effect is enhanced with the increase of concentration, but it can not exceed 1000mg/L, the concentration is higher than 1000mg/L, will make the grape leaf edge chlorosis, yellow, when the concentration exceeds 3000mg/L, it will be damaged for a long time and not easy to recover. Therefore, pay attention to the concentration of sprays; Different varieties of grapes do not have the same effect on the control of short grain, and the appropriate concentration should be selected according to the variety and natural conditions.
