Peanut flowering control five measures
Increasing production spirit has the function of promoting the operation of nutrients in plants, accelerating cell differentiation, preventing shedding, protecting flowers and protecting fruits, and promoting the role of grain filling and early maturation. During the flowering of peanuts, spraying 10~3010-6 liquids for 1 or 2 times, the rate of follicles is reduced by 10%~20%, and the yield is increased by 10%~15% per 667 square meters, especially when it is used thinly to increase the yield. better. For a long time, it is a kind of artificial plant growth retardant, which promotes the slow growth of stems and leaves, the full maturity of pods, the full fruit rate, and the high rate of rice output. Generally, it increases production by about 10%. The plots with high fertility, high nitrogen fertilizer, and leggy phenomenon were sprayed at a concentration of 1000-150010-6 in the middle of the flowering stage to the middle stage of the crust. Thin ground, poorly developed peanuts should not be sprayed, otherwise it will lead to reduced production. CCC is generally used in peanut plots with high fertility, overgrowth, leggy and lodging, spraying 3000 to 500010-6 liquids at full bloom, which can increase production by 5.8% to 18.8%. 2,4-D Mainly used for soaking and spraying. The effect of spraying is better during the period of flowering to flowering. The group of trees with a period of 50 ~ 7010-6, can increase production 5% ~ 9.3%; Shenghua period 3010-6, increase production by about 10%. Trichlorobenzoic acid is a new type of regulator. After the peanuts are sprayed, the plant height increases, the leaves increase and thicken, the chlorophyll content increases, and the photosynthetic efficiency increases. Therefore, the number of single plants, the fruit rate, the single plant weight, the whole fruit weight One hundred and one hundred weight increased, and the rate of double nuts was high. At the beginning of flowering, the spray of 100~30010~6 flower liquid can be increased by about 20%.
