我们这次考察的团场,开垦前士壤盐碱严重,长期以来,团场广大职工在改土、培肥方面做了大量工作,并在农业生产上取得了显著的成绩。 一、概况 团场的有机肥料来源主要有(1)畜牧业(以养猪为主,兼养牛、马、羊等)为农业提供的厩肥,但积肥数量有限,施肥面积不大;(2)种植多年生苜蓿,一般约占播种面积的10—15％,每年轮翻一定面积的苜蓿,解决部分粮棉作物的基肥问题;(3)麦田套种草木樨或麦收后播油菜,秋季种麦前翻压鲜草,解决部分麦田基肥不足的矛盾;(4)秸秆直接还田,由于受多种因素(如水分、燃料等)的限制,目前尚未实行,但是个别团场(如29团场)有利用稻草通过垫圈间接还田的事例。
The field we inspected this time was seriously affected by salinization of the former satellites. For a long time, the vast majority of staff and workers in the field have done a great deal of work in soil improvement and fertilization and have achieved remarkable successes in agricultural production. I. General The main sources of organic fertilizers in the field are: (1) Livestock husbandry (mainly pig raising, raising cattle, horses, sheep, etc.) provides manure for agriculture but there is a limited amount of fertilizer and a small area for fertilization; ) Planted perennial alfalfa, usually about 10-15% of the sown area, turning a certain area of alfalfa every year to solve part of the problem of base grain and cotton crops; (3) (4) straw directly back into the field, due to a variety of factors (such as moisture, fuel, etc.), has not yet been implemented, but individual groups (such as 29 groups field There is an example of using straw to indirectly return to the field through a washer.
