一、关于绿肥的堆制问题七四年下半年开始,白朗县团结公社各生产队先后进行绿肥的堆制,七五年遍及到全县。由于领导狠抓,群众大干,开辟了新的肥沅,为农田增施肥料,改良土壤,提高产量起到了一定的作用。堆制绿肥,主要目的是增施肥料,其次还可以减少杂草。从杂草的危害和牲畜饲草等方面考虑,我们提出堆制绿肥的杂草,主要是“江则”(大蓟)和“色马” (西藏紫云英),其中“江则”对农作物危害很大。生长在田间的“江则”与庄稼严重争肥夺水,生长速度快,一般可长到与小支一样高,坡地、河边、田间到处都有,搜集起来是很容易。而“色马”大都生长在山坡下,地埂边,不占农田,对庄稼无直接危害,但它属豆科,有效氮含量高,肥效比前者好。燕麦草生长最多,是危害很大恶性的杂草,但 First, on the compost system of green manure Seventy-four years from the second half of the year, the White Langxian unity of the commune of the production team has a green manure heap, 75 throughout the county. Due to the fact that the leadership is paying close attention to the situation, the masses are doing a lot and they have opened up new fertilizers that have played a certain role in fertilizing farmland, improving soil and increasing output. Composting of green manures, the main purpose is to increase fertilizer, followed by reducing weeds. From the perspective of weed damage and livestock fodder, we propose weeds for green manure compaction, mainly “Jiang Ze” (big thistle) and “color horse” (Tibetan Shi Yun Ying), of which “Jiang Ze” Crops are very harmful. Growing in the field, “Jiang Ze” and crops seriously fight fertilizer, growing fast, generally grow to the same height as the small branches, slopes, riverside, field everywhere, it is easy to collect. The “color horse” are mostly grown in the hillside, to the edge, does not account for farmland, no direct harm to the crops, but it is legumes, effective nitrogen content, fertilizer efficiency than the former. Oats grow most, and are very harmful to weeds, but
