Method for enhancing stress resistance by applying soil activator to medium indica rice field

Abstract

The invention discloses a method for enhancing the stress resistance by applying a soil activator to a medium indica rice field, and relates to the technical field of crop cultivation. The method comprises the following steps: at the 50th day after a medium indica rice machine transplants rice, after indica rice is subjected to stem elongation and before the booting stage, building a water pond of 0.2 m<3> on the side of the medium indica rice field, covering the bottom of the water pond with a plastic thin film, then injecting 0.2 m<3> of river water into the film-covered water pond, feeding 4 kg of brown sugar and 2 kg of the soil activator into the water pond, and uniformly stirring the materials for fermentation for 24 hours, thus obtaining mother liquid; adding water into 200 kg of the mother liquid for dilution till the total weight is 2,000 kg, and uniformly sprinkling the diluent into the medium indica rice field of 2 hectares; after one month, performing secondary application of the same diluent. According to the method, the soil activator is applied to the medium indica rice field to realize structural modification for micropopulations and nutrients in the soil and enhance the stress resistance of rice plants in the middle and later periods. The pond is built on the side of the rice field for fermentation, thus producing the mother liquid; by mixing of the soil activator and the brown sugar for fermentation, the improvement effect of the soil activator on the soil in the medium indica rice field can be obviously enhanced.

Description

[0001] Technical field: [0002] The invention relates to the technical field of crop cultivation, in particular to a method for enhancing stress resistance by applying a soil activator in a medium indica rice field. [0003] Background technique: [0004] Indica, a subspecies of cultivated rice. The first cultivated rice was domesticated from wild rice. Compared with japonica rice: stronger tillering ability; wider leaves, light green leaf color, more hairy leaves; slender grains. Paddle hairs are short, easy to shed when mature, and the rice production rate is slightly lower; the cooked rice has weak viscosity and large expansion; it is relatively resistant to heat and strong light, and weak in cold resistance. Mainly distributed in China, South Asia, Southeast Asian countries, and tropical Africa. China is mainly distributed in the Huaihe River, the areas south of the Qinling Mountains and the low-altitude areas of the Yunnan-Guizhou Plateau. [0005] Indica rice can be ...

AI Technical Summary

Problems solved by technology

[0005] Indica rice can be divided into early indica rice, middle indica rice, and late indica rice. In the prior art, the rice fields are seriously overrun, and the soil microbiota and soil nutrient structure are becoming more and more unfavorable for the production of middle indica rice, resulting in the weakening of the stress resistance of middle indica rice and the yield not very high
