棉花省肥高产栽培技术是我所经过三年摸索省肥高产途径,二年进行大田对比试验和一年生产示范而成。1977～1978年在所内小面积试验,其中77～78年试验田面积1.02亩,亩产皮棉分别为210.2,216.6斤,79年1.42亩,亩产271.8斤,80年2.62亩,亩产207斤,81年2.02亩,亩产216.1斤。从82年起,将所内小面积科研试验成果拿到玉山县四类型棉田中去进行验证,作大田生产示范,两年都取得了同样的效果,充分证明这一省肥高产植棉技术,在我区丘陵红壤水稻土田是适用的,是可以大大提高氮肥的经济 Fertilizer cotton high-yielding cultivation technology is that after three years I have found ways to fertilize high-yield, two years of comparative field trials and one year production demonstration. From 1977 to 1978, a small-area test was conducted in this area. The area of ​​experimental fields in 1977-78 was 1.02 mu, with 210.2,216.6 kg of mu produce per mu, 1.42 mu of 79 mu, 271.8 kg of mu per mu, 2.62 mu of 80 mu, 2.02 mu 81 years, 216.1 kg per mu. From 82 onwards, the small area of ​​the research results obtained from the four types of cotton fields in Yushan County to verify for field production demonstration, have achieved the same effect for two years, fully proved that the province of high-yielding cotton plant technology in My hilly red soil paddy field is applicable, can greatly enhance the economy of nitrogen fertilizer
