Embodiment 1

[0029] 1. Preparation of composite spraying agent

[0030] Preparation of component A: mix 2.24g methyl jasmonate with 5ml ethanol, fully dissolve to obtain methyl jasmonate mother liquor; add 5ml methyl jasmonate mother liquor and 2.76g spermidine to 995ml water, fully stir to dissolve , to obtain component A.

[0031] Preparation of component B: Air-dry young ears of sweet corn, grind them to obtain a powder of 0.10-0.15mm (particle size), take 200g of powder and place it in 4L of water at room temperature for 3 days, filter out the insoluble matter, and obtain the composition Point B.

[0032] Mix component A and component B at a ratio of 1:20 (v / v) to obtain a composite spraying agent.

[0033] 2. Spraying of compound spraying agent

[0034] 1. Test materials: sweet corn inbred lines T49-2-6-1-1(♀) and S29-6-2-3(♂)

[0035] 2. Test agent: composite spraying agent

[0036] 3. Test method

[0037] Before the ear of the female parent is silked, bagging is carried out, a...

Embodiment 2

[0047] 1. Preparation of composite spraying agent

[0048] The 4 groups of spraying agent treatments and 1 group of control treatments designed in this embodiment are the same as in Example 1.

[0049] 2. Spraying of compound spraying agent

[0050] 1. Test material: F1 seeds of sweet corn inbred lines T49-2-6-1-1(♀) and S29-6-2-3(♂) hybrid.

[0051] 2. Test method

[0052] Seed Germination Test: Germination tests were performed on seeds harvested 26 days after pollination. Refer to the ISTA inspection regulations, use 6×12cm wet paper rolls to germinate, and repeat 4 times, with 100 seeds per repetition. The seeds were placed in a constant temperature incubator at 25°C, and the light setting was 12h light / 12h dark. With the germination standard of radicle breaking through the seed coat by 1 mm, the number of germinations was recorded every day, and the germination potential and germination rate were calculated on the 4th and 7th days of germination, respectively.

Abstract

The invention discloses a compound spraying agent and application thereof in promotion of crop kernel filling and seed viability. The compound spraying agent is prepared from a component A and a component B according to the volume ratio of 1:(1-100), wherein the component A takes water as a solvent and contains 1-50 mM of spermidine, 1-15 mM of jasmonic acid methyl ester and 10-50 mM of ethanol, and the component B is a sweet corn young ear extracting solution. According to the compound spraying agent, spermidine and jasmonic acid methyl ester are taken as effective ingredients of the spraying agent and mixed with the sweet corn young ear extracting solution, and by spraying the spraying agent to leaf surfaces or female ears of crops at the appropriate concentration, dry matter accumulation of sweet corn kernels is effectively promoted, the thousand kernel weight of sweet corn is increased, and the harvested seed viability is improved.

Description

technical field [0001] The invention relates to the technical field of crop production, in particular to a composite spraying agent and its application in promoting crop grain filling and seed vigor. Background technique [0002] Sweet corn, also known as vegetable corn, is one of the fastest-growing new vegetable varieties in recent years. [0003] Sweet corn is loved by consumers from all walks of life because of its rich nutrition and sweet, fresh, crisp and tender characteristics. In recent years, the planting scale of sweet corn has maintained a steady increase year by year, the export volume has continued to increase significantly, the breeding of new varieties has been further accelerated, the scale of post-harvest processing has continued to expand, and the planting income has maintained a positive momentum. However, the low quality of sweet corn seeds seriously hinders the development of sweet corn industry. At present, the price of sweet corn seeds is expensive i...
