Embodiment 1

[0012] Embodiment 1: spring peanut field test

[0013] The inhibitor that is paclobutrazol by weight ratio: calcium prohexadione: uniconazole=3: 1.2: 0.8 is sprayed on the peanut of test field; Wherein,

[0014] (1) 15% paclobutrazol wettable powder 30g / mu, active ingredient 4.5g / mu.

[0015] (2) 5% wettable powder prohexadione calcium 36g / mu, active ingredient 1.8g / mu.

[0016] (3) 5% wettable powder uniconazole 24g / mu, active ingredient 1.2g / mu.

[0017] 1. The effect of delaying the aging of peanut leaves

[0018] The results in Table 1 show that after applying the formula of the present invention, LAI and effective LAI in the later stage of peanut growth, leaf membrane lipid protection enzyme activity (SOD, POD, CAT) and Pr content etc. are significantly improved, and MDA is significantly reduced. Wherein the processing LAI and effective LAI of spraying clear water increase more than 20%, than the processing of single spraying paclobutrazol, increase more than 50%; Inc...

Embodiment 2

[0026] Embodiment 2: Field experiment of wheat interleaved with peanuts

[0027] The inhibitor that is paclobutrazol by weight ratio: calcium prohexadione: uniconazole=3: 1.3: 1 is sprayed on the peanut of test field; Wherein,

[0028] (1) 15% paclobutrazol wettable powder 30g / mu, active ingredient 4.5g / mu.

[0029] (2) 5% wettable powder prohexadione calcium 40g / mu, active ingredient 2g / mu.

[0030] (3) 5% wettable powder uniconazole 30g / mu, active ingredient 1.5g / mu.

[0031] 1. The effect of delaying the aging of peanut leaves

[0032] The results in Table 3 show that the formulation of the present invention can significantly improve LAI and effective LAI, leaf membrane lipid protection enzyme activity (SOD, POD, CAT) and Pr content of peanuts in the later growth period, and reduce MDA content. Wherein it increases more than 18% than the processing LAI and effective LAI of spraying clear water, and increases more than 30% than single-spraying paclobutrazol; the membrane ...

Embodiment 3

[0040] Embodiment 3: spring peanut field test

[0041] The inhibitor that is paclobutrazol by weight ratio: prohexadione calcium: uniconazole=3: 1.5: 1.2 is sprayed on the peanut of test field; Wherein,

[0042] (1) 15% paclobutrazol wettable powder 30g / mu, active ingredient 4.5g / mu.

[0043] (2) 5% wettable powder prohexadione calcium 46g / mu, active ingredient 2.3g / mu.

[0044] (3) 5% wettable powder uniconazole 36g / mu, active ingredient 1.8g / mu.

[0045] 1. The effect of delaying the aging of peanut leaves

[0046] The results in Table 5 show that after applying the formula of the present invention, LAI and effective LAI, leaf membrane lipid protection enzyme activity (SOD, POD, CAT) and Pr content of peanuts in the late growth period are significantly improved, and MDA is significantly reduced. Wherein the processing LAI and effective LAI of spraying clear water increase more than 11%, than the processing of single spraying paclobutrazol, increase more than 39%; Increas...

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 [0001] The invention relates to an agricultural technology, in particular to a multifunctional peanut growth inhibitor. Background technique [0002] We know that chemical control technology is one of the main technical measures for peanut high-yield cultivation. From the mid-1970s to the end of the 1980s, the growth inhibitor used in peanuts was B9 (butyrhydrazide). Later experiments proved that diethylhydrazide could easily cause carcinogenesis and teratogenicity in humans, and it was banned internationally. It was replaced by paclobutrazol (PP333). Because paclobutrazol has the advantages of less dosage per unit area and low price per unit weight, it has become the leading product for controlling peanut lodging in my country. However, paclobutrazol has obvious side effects, the most prominent of which are causing aggravation of leaf diseases in the late growth period of peanuts, premature senescence of plants, accelerated leaf shedding, and affecting po...
