Method for inhibiting flourishing growth of rice

Abstract

The invention provides a method for inhibiting flourishing growth of rice, and relates to the technical field of rice planting. The method comprises the following steps: (1) fertilization: applying fertilizers to rice in a seedling stage, and controlling the ratio of nitrogen, phosphorus and potassium to be 1:3:2; (2) carrying out root breakage treatment on the rice in the medium stage of tillering of the rice, wherein a root breakage position is at the 5-8-centimeter position of the outer side of a rice rhizome, and the depth of a broken root is 4-6 centimeters; (3) carrying out water breaking and field drying treatment on the rice in the later period of tillering of the rice until white roots of the rice are exposed, wherein the temperature is 25-30 DEG C during field drying; (4) water changing: draining water in a rice field at night, and then irrigating water in a deep well into the rice field, wherein deep trenches are dug between adjacent lines of the rice before irrigating the water of the deep well to the rice field; and (5), spraying a growth inhibitor solution into the rice field, wherein the mass percentage of the growth inhibitor solution is 0.01-0.03%, and 10-15 kilograms of the growth inhibitor solution is sprayed in every mu of the rice. By the method, the rice flourishing growth inhibiting effect is good, the yield of the rice can be improved effectively, and the economic benefit is improved.

Description

Technical field: [0001] The invention relates to the technical field of rice planting, in particular to a method for suppressing vigorous growth of rice. Background technique: [0002] If the amount of nitrogen fertilizer in rice is too large, the rice will have excessive tillering, crazy growth of stems and leaves, weakened stress resistance and late maturity. The phosphate ion of phosphorus fertilizer is absorbed by rice, which can make rice early tillering and early rooting, so as to improve root system development and enhance the drought resistance and cold resistance of rice. When the phosphorus fertilizer is insufficient, the root development of rice will be affected, which will lead to the reduction of rice tillers, and the leaves will be dark green and dull. Potassium fertilizer can promote the formation and transformation of carbohydrates, and can enhance the ability of rice to resist low temperature, high temperature and drought. Potassium fertilizer can also pro...

Problems solved by technology

After rice tillering, due to the suitable climate, it is very easy to cause the plants to grow vigorously and excessively, which can easily lead to closed canopy in the field, weak stems, too many ineffective tillers, and easy lodging in the later stage, which is extremely unfavorable for the stable and high yield of rice.

At the same time, it also causes waste of nutrients. Due to the large transfer of nutrients to the plants, it is very easy to cause nutritional deficiencies at the booting stage and filling stage of rice in the later stage, resulting in the high probability of empty shells and grains, and finally resulting in a reduction in yield.
