Problems solved by technology

However, paclobutrazol is extremely difficult to dissolve in water, and even wettable powder cannot completely dissolve it, so it is difficult to determine and guarantee the practical effective concentration.
What is even more worrying is that the residual period of paclobutrazol in the soil is as long as 2 to several years, which directly damages the ecological environment and affects the growth and development of subsequent crops, especially dicotyledonous crops, so that some experts strongly call for the prohibition of paclobutrazol

Embodiment 1

[0013] The experiment was carried out in the agricultural teaching and scientific research base of Guangxi University, and the management of water and fertilizer and the control of diseases and insect pests followed the routine (the growth regulator of the present invention can not replace any fertilizers and pesticides). As mentioned above, foliar spray mixture (benzyl amine 100mg L -1 +Sodium bisulfite 300mg·L -1 ); Water spray was used as the control (CK). As a result, compared with the CK group, the yield per unit area of ​​the treatment group increased by 22%, the fruit filling rate increased by 2.45%, the kernel weight increased by 1.68%, the protein content increased by 2.01%, and the fat content increased by 0.1%.

Embodiment 2

[0015] The experimental location and method are the same as above. The mixture ratio is 300mg·L of benzylamine -1 +Sodium bisulfite 100mg·L -1 . Results Compared with the CK group, the yield per unit area of ​​the treatment group increased by 30.25%, the fruit filling rate increased by 1.34%, the kernel weight increased by 1.88%, the protein content increased by 5.26%, and the fat content increased by 0.31%.

Embodiment 3

[0017] The experimental location and method are the same as above. The mixture ratio is 200mg·L of benzylamine -1 +Sodium bisulfite 200mg·L -1 . Results Compared with the CK group, the yield per unit area of ​​the treatment group increased by 29.71%, the rate of full fruit increased by 2.06%, the weight of 100 kernels increased by 1.79%, the protein content increased by 2.43%, and the fat content increased by 0.2%.

Abstract

The invention discloses a peanut growth regulator and a use method thereof. The growth regulator is prepared by blending pix and sodium bisulfite, wherein the proportion of the weight-volume concentration mg.L of the pix and the sodium bisulfite is 100-300 to 100-300. The use method for the peanut growth regulator is as follows: after peanut sprouts grow to first florescence of 6 to 7 leaves, spraying the peanut growth regulator to the leaves twice in interval of one week. As a result, the yield per unit is improved by more than 20 percent, and the growth regulator improves quality, full fruit rate, seed weight, protein and fat content remarkably. The blending agent has the advantages of low cost, convenient use and environmental protection, and is safe and nontoxic to soil ecology, people and animals.

Description

technical field [0001] The invention belongs to a plant growth regulator and its application method, in particular to an environment-friendly peanut growth regulator and its application method. Background technique [0002] As a major oil crop and protein crop, peanut (Arachis hypogaea L.) plays an important role in the national economy and household diet. In South China, according to the sowing season, it is divided into spring and autumn, and spring peanuts are the main ones. However, the entire growth period of spring peanuts is mainly in the high temperature and rainy season, which is prone to excessive shoot growth during flowering and after flowering, reducing the distribution of photosynthetic products to pods, thereby reducing yield and quality. For this reason, since the 1980s, people have carried out a large amount of research with the growth retarder PP333 (paclobutrazol), and obtained some positive results. However, paclobutrazol is extremely difficult to disso...
