Field management method for weakly basic rice

Abstract

The present invention provides a field management method for weakly basic rice to effectively increase the yield of the weakly basic rice per mu. The field management method for weakly basic rice includes a water layer management method including: a seedling establishment stage at which the field water level is kept at 2 / 3 of seedling bodies to ensure that centers of seedlings are not flooded; a tillering stage at which the field water level is kept at 2.8-3.2 cm; a jointing-booting stage at which the field water level is kept at 3-5 cm; and a heading and grain formation stage at which a 3-5 cm shallow water layer is intermittently irrigated, wherein intermittent irrigation means that the 3-5 cm shallow water layer is irrigated once and is naturally drained until there is water in tracks,then, the 3-5 cm shallow water layer is irrigated once more, and the operation is repeated in such a way; and the heading and grain formation stage includes a filling stage, a milk-ripe stage and a dough stage, wherein at the filling stage, the time interval between the operation that the water is naturally drained until there is water in the tracks and the operation that the 3-5 cm shallow waterlayer is irrigated once is 1-2 d, and at the milk-ripe stage and the dough stage, the time interval between the operation that the water is naturally drained until there is water in the tracks and theoperation that the 3-5 cm shallow water layer is irrigated once is 3-5 d.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a field management method for weakly alkaline rice. Background technique [0002] Rice is one of the main crops in my country. Its growth cycle is short and its yield is high. It is not only deeply loved by the people, but also meets the needs of my country's large population. With the development of rice planting technology and the improvement of rice yield requirements, more and more areas are currently planting rice by transplanting. Through transplanting, the planting density of rice can be reasonably arranged, and the root system can be developed. Prevent lodging from happening. Rice, which is widely planted at present, is an alkaline food. Studies have found that acidic food will acidify the blood after being digested and absorbed by the human body, causing various diseases. Eating more alkaline and weakly alkaline foods can maintain the blood is weakly alkaline , s...

Problems solved by technology

As we all know, water management in the whole development cycle of rice can change the physical and chemical conditions of the soil, such as organic matter content, redox potential, pH value, etc., thereby affecting the growth of rice, and ultimately affecting the yield per mu of rice
