毛苕子是好绿肥,又是好饲草,目前主要的问题是种子不足。从1978年开始,我们进行了毛苕小麦间作留种试验,初步取得较好的效果。间作的好处 1.增加经济收益。毛苕小麦间作,毛苕有依托,苕籽增产,小麦不减产。连续3年在大田调查,小麦毛苕混播比单播小麦的亩产值分别增加了46.83元、15.63元和21.91元。 2.培肥地力,两料增产。据4年试验观测,麦苕混种地,每亩留根488.2万条。麦收后采土测定,单种小麦地有机质含量为1.04％,而苕麦混和地为1.11％。1980年及1981年试验,单种茬后作玉米亩产718.2斤及619.2斤,混种茬比单种茬分别增产10.8％及13.8％。 3.秸秆富有营养。分析秸秆风干物中的粗
Hairy seed is good green manure, but also good forage grass, the main problem is the lack of seeds. From 1978 onwards, we conducted the intercropping of wheat wool intercropping test, initially achieved good results. The benefits of inter-working 1. Increase economic returns. Mulao wheat intercropping, hairy relying on, seeded seed yield, wheat is not cut. For 3 years in a row in Daejeon, the output value per mu of maogeoni mixed with unicast wheat increased by 46.83 yuan, 15.63 yuan and 21.91 yuan respectively. 2 fertilize fertility, two materials increase production. According to 4 years of experimental observation, wheat stubble mixed with 4,882,000 acres per acre root. After harvesting wheat, soil organic matter content of single wheat was 1.04%, while that of oatmeal was 1.11%. In 1980 and 1981, 718.2 kg and 619.2 kg per acre per acre were obtained after single cropping, and mixed crop increased 10.8% and 13.8% respectively over that of single cropping. 3. Straw is nutritious. Analysis of straw dry materials in the rough
