Method for controlling vigorous growth of peanuts

Abstract

The invention belongs to the technical field of agricultural production plant growth regulator, and discloses a method for controlling the vigorous growth of peanuts. The method is characterized in that in the final stage of the blossom falling period of peanuts and the pod bearing period and when the height of plants is 40-45 cm, a flumetralin preparation is applied, the effective component is flumetralin, and the weight of flumetralin accounts for 5%-70% of that of the agent. The effect of the growth regulator of flumetralin is utilized to control the vain growth of stems and leaves of the peanuts, the length of the main stems and lateral branches is reduced, unnecessary consumption of nutrient substances on plants is lowered, the nutrient substances are transferred to underground pods,therefore the growth of the pods is promoted, so that the plants are stocky, lodging is prevented, the fruit result is improved, the pod plumpness is improved, and the yield is increased.

Description

technical field [0001] The invention belongs to the technical field of plant growth regulators for agricultural production, and in particular relates to a method for controlling the flourishing of peanuts and having the effect of increasing yield. Background technique [0002] Peanut is an important oil crop, cash crop and foreign exchange earning crop in China. It plays an important role in my country's edible oil supply, food processing, export earning foreign exchange and farmers' income increase. [0003] It has become an indisputable fact that peanuts are in the peak growth period. If the management is not good, the peanuts will grow crazily and excessively, and only seedlings will grow but not bear fruit. Under the conditions of sufficient water and fertilizer, high temperature and good light, the growth speed of peanuts is accelerated, which can easily cause the stems and leaves to grow excessively. This kind of vigorous growth has no direct beneficial effect on the i...

Problems solved by technology

[0006] The application of paclobutrazol, a traditional peanut control agent, has the following problems: (1) Excessive dosage of paclobutrazol will seriously affect the development of peanut pods, making the fruit smaller and thickening the shell; Leaf diseases occur, causing the leaves to die and fall off in advance, causing premature plant aging; (3) paclobutrazol has a long residual effect in the soil, which will inhibit the growth of subsequent crops, so it is not suitable for continuous use;

[0007] The application of the new peanut control agent prohexadione calcium has the following characteristics: (1) the control of peanut growth by prohexadione calcium is milder than that of paclobutrazol, and it can regulate and control the growth of peanuts in a long period of time; (2) Calcium prohexadione is safe for peanuts and will not cause small or stiff peanuts; (3) However, the price of the original drug of calcium prohexadione is too high, and the cost of use is too high, so it is difficult to popularize and use it on a large scale
