Abstract
The invention relates to a multi-functional peanut growth inhibitor which is composed by the weight ratio of following components, paclobutrazol to prohexadione calcium to uniconazole is 3: 1.2-1.5: 0.8-1.2. The invention not only can effectively control the growth of the vegetative part of the peanut on the ground, can prevent the peanut from overgrowing and lodging, but also can effectively avoid the side effect brought by general growth inhibitor (e.g. paclobutrazol). At the same time, in the growth anaphase of the peanut, the invention can remarkably improve LAI (leaf area index), effective LAI, leaves membrane-lipid protective enzymatic activity (SOD, POD, CAT), Pr (soluble protein) content and so on, can reduce MDA content and can postpone the senescence rate of peanut leaves. More importantly, the invention can remarkably improve the output of pods. The production can be increased by 16.6 percent- 23.0 percent more than the production without spraying any inhibitor, and can be increased by 7.6 percent- 13.7 percent more than the production only spraying paclobutrazol. The invention solves the problem that the overgrowth and presenility can not be prevented synchronously in the production process of the peanuts.
Description
Technical field
The present invention relates to a kind of agrotechnique, specifically a kind of multifunctional peanut growth inhibitor.
Background technology
We know that chemical control technology is one of major technique measure of peanut high-yield culturing.From 20th century the mid-1970s to the end of the eighties, the growth inhibitor that peanut uses is B9 (daminozide).The experiment confirm daminozide easily caused human carcinogenic teratogenesis afterwards, was forbidden in the world.The substitute is paclobutrazol (PP333).Because paclobutrazol unit are consumption is few, advantage such as Unit Weight low price has in addition become the leading products of present China control peanut excessive growth lodging.But the paclobutrazol side effect is obvious, and what it was the most outstanding is to cause that peanut late growth stage leaf diseases increases the weight of, plant early ageing, and leaf abscission quickens, and influences the pod yield and quality.
Summary of the invention
The present invention is for overcoming above-mentioned the deficiencies in the prior art, a kind of multifunctional peanut growth inhibitor is provided, it can effectively suppress peanut plant overground part excessive growth lodging, the side effect that can effectively avoid conventional growth inhibitor (as paclobutrazol) to be brought has again solved to perplex always and prevents excessive growth in the peanut production and prevent that early ageing is difficult to synchronous problem.
The objective of the invention is to adopt following technical proposals to realize: a kind of multifunctional peanut growth inhibitor, form paclobutrazol by following composition by weight proportion: Prohexadione calcium: uniconazole P 3:1.2～1.5:0.8～1.2.
Described paclobutrazol is that to account for weight ratio be 15% paclobutrazol wetting powder to active ingredient.
Described Prohexadione calcium is that to account for weight ratio be 5% wetting powder Prohexadione calcium to active ingredient.
Described uniconazole P is that to account for weight ratio be 5% wetting powder uniconazole P to active ingredient.
The general English name of Prohexadione calcium among the present invention is prohexadione calcium, is a kind of unification compound, is yellow solid, is a kind of nuisance-free plant growth regulator, and effect resistant to lodging is arranged.Shanghai Chu Bai laboratory equipment Co., Ltd, Tianjin Braun Aktiengesellschaft all sell at present.
The simple mixing of above-mentioned three kinds of materials gets final product.Three kinds of its active ingredients of material of selling on the market have difference, but calculate by the active ingredient weight ratio when mixing.
The present invention not only can effectively control the growth of peanut overground part trophosome; prevent peanut excessive growth lodging; can significantly improve simultaneously peanut late growth stage LAI (leaf-area coefficient) and effective LAI, blade film fat protective enzyme activity (SOD, POD, CAT) and Pr (soluble protein) content etc.; reduce MDA content, delay the old and feeble speed of peanut leaf.The more important thing is that the present invention is remarkable to improving the effect of pod output, than the volume increase 16.6%～23.0% of not spraying any inhibitor, than the processing volume increase 7.6～13.7% of single spray paclobutrazol.Solved to perplex always and prevented excessive growth in the peanut production and prevent that early ageing is difficult to synchronous problem.
