意义日本国内对麦类的需要,虽然制粉用、酿造用、饲料用都在增加,但国内产麦量因低产而继续下降,故强烈期望确立一种更加省力高产的技术。不耕撒播栽培法,就是为满足这一渴望,于1964年开始考虑,同年秋到1989年春进行技术化研究,初步制定了其基本形式。其特点如下:“水稻收割后不翻耕,把种子和肥料全面撒播在稻田里,立即覆盖稻草”,是一种只要撒播除草剂和追施肥料,而不需翻耕、中耕、培土等一切作业的省力栽培法。因为不要翻耕,所以翻耕机械及其劳力也可省去,而且,下雨后稻田即使变得有些潮湿,播种及其它作业也能够 Significance Although the demand for wheat in Japan is increasing for milling, brewing and feed use, the domestic wheat output continues to decline due to low production. Therefore, it is highly desirable to establish a more labor-saving and high-yielding technology. In order to satisfy this desire, non-plowing and sowing cultivation methods began to be considered in 1964, and from the autumn of the same year to the spring of 1989, technical research was carried out and the basic form was initially formulated. Its characteristics are as follows: “Rice is not plowed after harvest, and the seeds and fertilizers are completely sown in the rice fields, immediately covering the straw”, which is a method of spreading herbicides and topdressing fertilizers without any need of tillage, cultivating or soil-cutting. Labor-saving cultivation practices. Tillage machinery and its labor can also be dispensed with because it is not tillage, and even if it becomes damp after the rain, planting and other operations can
