Embodiment 2

[0065] The formula of T2 in the table 1 of embodiment 1 (a preferred embodiment of the present invention) has been selected to complete the test of the spraying concentration of the present embodiment. Specifically: according to the amount added in kind: 15% paclobutrazol wettable powder is 20 kg, potassium dihydrogen phosphate is 50 kg, borax is 25 kg, zinc sulfate is 2.5 kg, manganese sulfate is 1.5 kg, ammonium molybdate is 0.5 kg, Copper sulfate is 0.5 kg. Prepare according to the steps of Example 1. Four test concentrations of 1:2000, 1:1000, 1:500, and 1:250 were designed for the spraying concentration, respectively recorded as T21, T22, T23, and T24 (see Table 5-Table 7 for the implementation effect).

Embodiment 3

[0066] Embodiment 3 (field application example 1)

[0067] Field test example 1 (the test rapeseed variety is Huayouza No. 6, an open promotion variety selected and bred by Huazhong Agricultural University), the test design has 5 test formulas of rapeseed (respectively denoted as T1, T2, T3, T4, T5), with clear water as the control (CK), a field experiment was carried out on rape variety Huayouza No. 6.

Abstract

The invention relates to the technical field of crop cultivation, and relates particularly to a rape seedling strengthening agent and a preparation method thereof. The rape seedling strengthening agent composition comprises 30-55 weight parts of potassium dihydrogen phosphate, 17.5-32.5 weight parts of borax ,16-32 weight parts of 15% Paclobutrazol wettable powder, 2-4 weight parts of zinc sulfate, 1-3 weight parts of manganese sulfate, 0.25-1 weight parts of copper sulfate, and 0.25-2 weight parts of ammonium molybdate 0.25-2. The invention also discloses a preparation method and an application of the rape seedling strengthening agent composition.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a seedling-strengthening element for rapeseed and a preparation method thereof. The seedling-strengthening element is mainly used in rapeseed production to improve the robustness of rapeseed seedlings, improve the stress resistance of seedlings, and thereby increase rapeseed output . Background technique [0002] The growth and development of plants, such as cell division, elongation, differentiation and organ formation, as well as flowering and fruiting, maturation, aging, shedding, etc., are closely related to the nutritional status of plants and the phytohormones produced in their bodies. Artificially synthesized plant growth regulators also have the above-mentioned functions on the growth and development of plants. Such as promoting rooting of seedlings, breaking seed dormancy and accelerating seed germination, regulating plant type, regulating bolting, ...
