Embodiment 1

[0028] Example 1: Ascophyllum nodosum extract mixed with Ruppia maritima extract in a ratio of 3:2

[0029] Measure 300ml of Ascophyllum nodosum extract and 200ml of Ruppia maritima extract and mix well to prepare stable and uniform water preparation PJ-A32.

[0030] PJ-A32 starts to be used at the 2.5 leaf stage of pepper seedlings, once in November, December and January 2020, a total of 3 times of use, the dosage per mu is 100ml, diluted with water to 300 times to drench the roots.

[0031] The control agent is 25% propiconazole emulsifiable concentrate, which is diluted to 1500 times and sprayed on the leaves. The spray volume per mu is 30 liters, and the leaves are sprayed 15 days before transplanting in January 2020.

[0032] On the day of transplanting, measure the height of the main stem and the fresh weight of the root system; observe the slow seedling rate 7 days after transplanting; observe the survival rate 30 days after transplanting; record the final red pepper yi...

Embodiment 2

[0037] Example 2: Ascophyllum nodosum extract mixed with Potamogeton pectimatus extract in a ratio of 4:1

[0038] Measure 400ml of Ascophyllum nodosum extract and 100ml of Potamogeton pectimatus extract, mix and shake well to prepare a stable and uniform water dose PJ-B41.

[0039] PJ-B41 is used at the 2.5-leaf stage of strawberry seedlings, once a month from April to August, and used 5 times in total.

[0040] The contrast agent was 25% prochloraz emulsifiable concentrate, sprayed 600 times on the leaves, and the amount of spray per mu was 30 liters, 7 times in a row from May to August.

[0041] Measure plant height and root fresh weight on the day of transplanting; observe the slow seedling rate 10 days after transplanting; observe the survival rate 45 days after transplanting; record the initial flowering period:

[0042] Test treatment: PJ-B41; Plant height (cm): 16.1; Plant height reduction (%): 47.7; Root weight (g): 7.4; Root weight / plant height: 0.46; Slow seedling ...

Embodiment 3

[0046] Example 3: Ascophyllum nodosum extract mixed with Sargassum thunbergii extract in a ratio of 5:2

[0047] Measure 500ml of Ascophyllum nodosum extract and 200ml of Sargassum thunbergii extract, mix and shake well to prepare a stable and uniform water dose PJ-C52.

[0048] PJ-C52 is sprayed with 300 times liquid leaves when the cotyledons of watermelon seedlings are flattened, and used once in the whole seedbed stage.

[0049] The control agent is 15% paclobutrazol, which is sprayed on the leaves at the same period at a concentration of 10 mg / L, and used once in the whole seedbed stage.

[0050] Transplant at the three-leaf one-heart stage, measure the plant height and root length on the day of transplanting; observe the slow seedling rate 7 days after transplanting; record the initial flowering period:

[0051] Test treatment: PJ-C52; plant height (cm): 12.9; plant height reduction (%): 29.5; root length (cm): 6.5; root-shoot ratio: 0.50; June 4;

Abstract

The invention relates to the technical field of plant growth vigor regulation and control in the planting industry, and discloses a preparation method of a vigorous growth control product for green crops, which comprises the following steps: S1, employing the extracts of ascophyllum nodosum and some herbaceous plants (such as Ruppia maritima, Potamogeton pectimatus and Sargassum thunbergii) by adopting a low-temperature high-pressure bursting technology to serve as a raw material; s2, blending the ascophyllum nodosum extract and the herbaceous plant extract (such as Ruppia maritima, Potamogeton pectimatus and Sargassum thunbergii) according to the proportion of (3-8):(0.5-3) to obtain a brown uniform liquid (aqueous solution). According to the method, chemical agents are completely replaced for vigorous growth control, the requirements of green and organic agricultural product production are met, the seedling recovering time after transplanting is shortened, early blooming and fruitingare achieved, pure plant source materials are adopted for preparation, and the product is free of any chemical hormones.

Description

technical field [0001] The invention relates to the technical field of plant growth regulation and control in the planting industry, in particular to a preparation method and a use method of a green crop control product. Background technique [0002] Due to the unscientific use of base fertilizer, too much organic fertilizer, manure or chemical fertilizer rich in available nitrogen, etc., the seedling period of crops is vigorous, which affects the reproductive growth of crops, delays flowering and fruiting, reduces the yield of agricultural products, and even reduces the quality. [0003] Prosperity is a frequent crop growth disorder in planting management. The current solution is to apply chemical control products, such as paclobutrazol, mepiperium, uniconazole, prochloraz, tebuconazole and other plant growth regulators. [0004] Chemical flourishing control products represented by artificially synthesized plant growth regulators are widely used in planting practice. Althou...
