After the peanut enters the flowering needle stage, due to high temperature, frequent rainfall, due to excessive nutrients and water, it is very easy to cause growth, crazy growth, consumption of nutrients, not easy to needle, affecting the expansion of pods, thereby affecting the yield and quality of peanuts. The traditional method is to spray plant growth regulators such as paclobutrazol and encrozole, which can inhibit the growth of stems and leaves, but cannot promote the expansion of peanut pods. Today I will introduce you to a formula that integrates control and puffed fruit.
1. Introduction to formula
This formula is enectazole + choline chloride, which is a triprazole plant growth regulator and an inhibitor of gibberellin synthesis. It has a variety of effects such as controlling vegetative growth, inhibiting cell elongation, shortening internodes, dwarfing plants, promoting lateral bud growth and flower bud formation, and improving stress resistance. At the same time, it also has the effect of sterilization and disease prevention, which can effectively inhibit the growth of peanut stems and leaves, and prevent the occurrence of peanut leaf spot disease, brown spot disease and other diseases.
Choline chloride is also a plant photosynthetic promoter and a highly effective nutritional supplement, which can significantly increase the content of chlorophyll, soluble protein and plant carbohydrates in crop leaves, improve the activity of superoxide dismutase, increase the photosynthetic efficiency of leaves, and produce more nutrients to tubers and pods. Initiates early germination of the root primordium, promotes the early expansion of roots, tubers and pods, increases the rate of full fruit, and improves peanut yield and quality.
The compound use of the two can not only effectively control the growth of peanut stems and leaves, but also improve the photosynthesis of the leaves, promote the delivery of nutrients to the underground pods, promote the rapid expansion of the pods, make the grains fuller, and achieve the purpose of multi-effect.
2, How to use
(1) When the first use, a large number of peanut needles generally began to be pricked, and the field began to seal the ridge, the time in the Huanghuai area was about July 22-25. For plots with excessive plant growth, when the height of peanut plants exceeds 40 to 45 cm, 5% enoxazole wettable powder can be used 40 to 50 ml + 60% choline chloride water agent 15 to 20 ml, and evenly spray with 30 kg of water, which can effectively control the growth of stems and leaves, promote needle pricking and early results.
(2) The second use, 10 to 15 days after the first spray, the time is about August 10-20, for sufficient water and fertilizer, peanut stem and leaf growth is still too strong, plant height of 50 ~ 60 cm, can be used 5% enoxazole wettable powder 30 ~ 50 g + 60% choline chloride water agent 15 ~ 20 ml, with water 30 kg uniform spray, not only can control the growth of stems and leaves, but also promote the expansion of peanut pods, so that the seeds grow faster, improve yield and quality.
