Embodiment 1

[0017] Weigh 1 kg of gibberellin, 3 kg of cytokinin, 120 kg of zinc sulfate and 110 kg of borax, and mix them uniformly to obtain the anti-premature solid powder.

Embodiment approach

[0018] The implementation method proceeds as follows:

[0019] 1. Spray 160-240 grams of anti-premature solid powder per mu of rice, and add 15 kilograms of water before spraying.

[0020] 2. Spraying time: Within one week after the rice is fully eared, choose sunny or cloudy weather (pay attention to the weather forecast and prevent rain within 12 hours after spraying), preferably at 8:00-10:00 in the morning or 4:00 in the afternoon -Spray at 6:00 (spray in the afternoon is better).

[0021] 3. Configuration and spraying method: add water to the bucket, then pour the anti-aging compound into the water, shake it with a bamboo stick before spraying. Spray evenly on the rice leaves so that it does not flow down in strands.

[0022] 4. If the spray liquid comes into contact with the skin, please rinse it off with clean water as soon as possible.

Embodiment 2

[0024] Weigh 1 kg of gibberellin, 4 kg of cytokinin, 70 kg of zinc sulfate and 130 kg of boric acid, and mix them uniformly to obtain the anti-premature solid powder. First add 10-30ml of 1mol / L hydrochloric acid into 200ml of water, then add 80-100g of anti-premature solid powder into the water, shake evenly to form the water formulation.

[0025] The rice anti-premature aging method of the present invention is carried out according to the following steps:

[0026] Within one week after the full ear of rice, select fine weather or cloudy weather, and spray the compound agent described in claim 1 or 2, if it rains within six hours after spraying, it needs to be sprayed again; Add 15kg of water to 160-240 grams of anti-progeria solid powder, and spray 160-240 grams of anti-progeria solid powder per mu.

[0027] The method for preventing and treating premature senescence of rice of the present invention is evenly sprayed on rice leaves so that it does not flow down in strands. ...

Abstract

The invention discloses a combination agent for the control of premature senility of rice, forming premature senility resistant solid powder by the 4 ingredients of gibberellin, cytokinin, zinc sulphate and borax or boric acid with the proportion of 1 : 2-4 : 70-130 : 70-130 by weight. The inventive combination agent for the control of premature senility of rice can be prepared as aqueous agent, comprising the steps of: first, adding 1 mol / l of hydrochloric acid of 10-30ml into water of 200ml, then adding the premature senility resistant solid powder of 80-100g into the water, and stirring well to form the aqueous agent. The inventive method for the control of premature senility of rice is performed by the following steps of: one week after full heading of rice, blending the premature senility resistant solid powder of 160-240g or aqueous agent with water of 15kg well and spraying on a sunny or cloudy day. The invention has the characteristics of simple prescription, less usages, convenient use, remarkable increase production effect, high benefit cost ratio, etc. and remarkable effects for controlling premature senility, increasing production of rice, and increasing income of farmers.

Description

technical field [0001] The invention relates to a compound agent for preventing premature aging of rice and a method for preventing premature aging of rice, belonging to the field of agricultural technology. Background technique [0002] Premature senescence of rice refers to the withering of stems and leaves and premature aging of rice during the period from earing to maturity, resulting in poor grain filling, increased shriveled grains and reduced production. The stressful process is regulated by exogenous factors and unprogrammed sudden death can be avoided. The usual morphological characteristics are that the leaves are brownish brown, the leaves are slightly rolled longitudinally at the beginning, and then the top of the leaves is in a dead state of dirty white. , the seed-setting rate at the base of the ear is very low, the grain color is pale white, and the number of warped ears increases. According to the survey, premature senescence of rice in Jiangxi Province is ...
