自1988年春,陶老乡进行耕作制度和种撞业内部结构调整,实行科学种田,旱田改水田,低产变高产,一熟改多熟,将陶老乡自流灌区改种水稻达1.06万亩,单产450～500kg。可是,几年来稻茬麦单产严重下降,正常年景小麦单产只有160～260kg。作者长期通过实地调查研究,从中找出稻茬麦低产的原因。 一、稻茬麦低产原因 1、出苗率低,出苗不齐 稻茬麦田质地较粘重,含水量高,土体坚实,适耕期短,不易耕
Since the spring of 1988, Tao Lao tillage farming system and a variety of industry structure adjustment, the implementation of scientific farming, paddy fields to paddy fields, low yield and high yield, a cooked more cooked, the Tao old gravity irrigation irrigation area of up to 10,600 mu of rice, 450 ~ 500kg. However, in recent years, the yield of wheat stubble has seriously declined, and the average annual yield of wheat is only 160-260kg. The author through long-term field research, find out the reasons for the low yield of rice stubble. First, the low yield of rice stubble causes 1, the emergence rate is low, uneven stubble The wheat field texture is more sticky, high water content, soil is solid, short period of adaptability, not easy to cultivate
