毛苕子既是棉田和早秋的好绿肥,又是牲畜越冬的优质饲料。长期以来因为栽培粗放、出苗难,保苗不易,产草量很低。加之翻压和分解期易引起棉花缺苗,所以种植面积几起几落,1970年已基本不种。1971年我们在武功、扶风、兴平、三原等县农村基点开始进行试验,对毛苕的栽培技术作了较大的改进,使鲜草产量由冬前亩产1000斤左右提高到2000斤以上;春翻鲜草由亩产2000多斤,提高到4000—5000斤。目前毛苕栽培面积,又有了较大的发展,主要措施如下:(一)选用早发丰产品种。我省过去大面积应用的普通毛苕,冬前和早春生长缓慢,
Mao raccoon is both a good green manure in the cotton fields and early autumn, but also a high-quality feed for livestock overwintering. For a long time because of extensive cultivation, seedling difficult, seedling is not easy, low yield. Coupled with the pressure and decomposition of cotton easy to cause lack of seedlings, so planted area up and down several times, basically no species in 1970. In 1971, we started our experiments in the rural areas such as martial arts, fufeng, Xingping and Sanyuan counties, and made great improvements to the cultivation techniques of Maojiu, raising the yield of fresh grass from about 1,000 kg per mu before winter to over 2,000 kg ; Spring fresh grass by 2000 kilograms per mu, increased to 4000-5000 pounds. At present, the cultivation area of Mao Zao has another big development. The main measures are as follows: (I) Selection of early-onset high yielding varieties. In the past, large area of our province was used for common catfish, which grew slowly in winter and early spring.
