棉花合理密植是一项经济有效的增产措施。随着栽培技术的改进和适宜品种的出现。合理密植的幅度也在不断地发展变化。近几年来,密植棉花在各项技术措施的配合下,发挥了重要的增产作用.特别是丘陵旱薄地,植棉密度到八、九千株,甚至万株以上,其增产、早熟作用尤为显著。我县马谷田公社,地处浅山丘陵,土质瘠薄,条件较差,由于坚持采取“密植早打顶”的作法,全社六千多亩棉花连续八年过百斤。水肥地
Reasonable cotton density is a cost-effective stimulation of production. With the improvement of cultivation techniques and the emergence of suitable varieties. The rate of reasonable density is constantly evolving. In recent years, with the cooperation of various technical measures, close-planting cotton has played an important role in increasing yield, especially in the hilly drylands, where the density of cotton planting reaches 8-9,000 or even 10,000 or more, and its yield increase and precocity are particularly significant . Our county Ma Gutian commune, is located in shallow hills, infertile soil conditions are poor, due to adhere to the “close planting and early morning topping” approach, the whole community more than 6,000 acres of cotton over eight pounds for eight consecutive years.
