A multi-point balanced high-yield water and fertilizer management method for rice

Abstract

The invention belongs to the field of agricultural cultivation and discloses a multi-point balanced high-yield water and fertilizer management method for paddy rice. In a cultivation process of the paddy rice, a manner of less irrigation and more exposure, a plurality of times of little fertilization and a plurality of times of slight field draining is adopted for a long period; a fertilization manner adopts a seedling hole fertilization manner; a group regulation and control manner adopts stable and balanced growth at a full growth period; the multi-point balanced high-yield water and fertilizer management method for the paddy rice specifically comprises the following steps: cultivating seedlings; carrying out transplanting management and transplanting; carrying out reviving stage management and reviving; carrying out jointing early-period management and carrying out jointing; carrying out heading stage management. By adopting the multi-point balanced high-yield water and fertilizer management method disclosed by the invention, early ripening and rapid sprouting of the paddy rice are facilitated; low-position tillering is accelerated, the ear-bearing tiller percentage is greatly improved and the effective ear quantity is increased; large ears are easy to form; the growth vigor of a paddy rice field is balanced and consistent, individuals are healthy and strong and groups are coordinated; the quality of the groups is greatly improved and the photosynthetic efficiency is improved.

Description

technical field [0001] The invention belongs to the field of agricultural cultivation, and in particular relates to a "multi-point flat" balanced high-yield water and fertilizer management method for rice. Background technique [0002] In terms of rice growth, due to reasons such as soil preparation quality, variety characteristics, fertilization techniques, pest damage, etc., especially in recent years, rice fields have generally been mechanically plowed and machined. At present, in terms of rice management technology, fertilization is mainly one-time reapplication of tillering fertilizer. Fertilization method They are all applied widely, and there is a problem of uneven fertilization. At the same time, the water management method is basically ups and downs, and the field is re-dried in the middle stage, etc., which is not conducive to the stable tillering of rice in the early stage and the steady growth of the rice group in the middle stage. Cause individual and group deve...

[0002] In terms of rice growth, due to reasons such as soil preparation quality, variety characteristics, fertilization techniques, pest damage, etc., especially in recent years, rice fields have generally been mechanically plowed and machined. At present, in terms of rice management technology, fertilization is mainly one-time reapplication of tillering fertilizer. Fertilization method They are all applied widely, and there is a problem of uneven fertilization. At the same time, the water management method is basically ups and downs, and the field is re-dried in the middle period. Conflict between individual and group development, low group quality, resulting in low and unstable yield
