为了解决我省夏季绿肥作物适宜的品种問题,我們从1962年开始进行了绿肥作物品种引种栽培試驗。希望能够通过休闲田种植绿肥,选择出适宜的绿肥作物品种,为开辟肥源,提高地力提供科学技术資料。供試夏季绿肥作物品种共20种,其中有18种为豆科作物(绝大部份为一年生),主要包括:田菁、檉麻、猪屎豆等,以绿豆为对照,进行品种观察。主要观察項目有:生长发育情况、綠色体合成量高低,腐烂难易,根瘤生长状况等。 In order to solve the summer varieties of green manure crops in our province, we started from 1962 introduced varieties of green manure cultivation experiments. Hope that through the leisure field planting green manure, select the appropriate varieties of green manure, in order to open up fertilizer sources, improve soil fertility to provide scientific and technical information. There were 20 species of summer green manure cultivars tested, of which 18 were leguminous crops (most of them were annual). They mainly included: Sesbania, Abutilon theorium and Pig Dung Beans. The varieties were observed with mung bean. The main observation items are: growth and development, the level of green body synthesis, decay is difficult, the growth of nodules and so on.
