除草后播种是获得饲料作物高产的条件之一。饲料作物和杂草在农业生物群落中相互影响的研究表明,它们的相互关系具有竟争特点,从而导致相互抑制。杂草对料饲作物的不良影响决定于它们的生物学特性、耕作方式、生长条件等。作者于1974—1979年在试验田进行了饲料作物和杂草在农业生物群落中相互关系的研究。人为地在饲料作物与杂草之间创造了各种关系。小区面积1—5米~2,4—6次重 Seeding after weeding is one of the conditions for obtaining high yields of fodder crops. Studies of the interaction of forage crops and weeds in agricultural biomes have shown that they are characterized by competing relationships that lead to mutual suppression. Weeds adverse effects on feed crops depends on their biological characteristics, farming methods, growth conditions. The authors conducted a study of the interrelationship between forage crops and weeds in agricultural biomes in experimental plots in 1974-1979. Artificially created a variety of relationships between feed crops and weeds. Residential area of ​​1-5 meters ~ 2,4-6 times heavy
