为适应农业机械化要求,我组于1974年进行了小麦收后直播棉花试验,面积1亩,品种华棉4号。5月27日播种,10月29日拔杆,全生育期155天。亩产皮棉136斤。就以下几个方面谈一点体会。一、麦后花的生长发育特点(一)生育期缩短。麦后花全生育期缩短,这是对丰产不利的因素,但麦后茬也具备许多优点。主要是麦后花早期气温高,避开了苗期的寒害,苗病也较轻,容易全苗。本试验几
In order to meet the requirements of agricultural mechanization, our group carried out a direct seeding cotton harvest test in 1974 with an area of 1 mu and the variety Hua Mian No.4. May 27 sowing, October 29 pull the pole, the whole growth period of 155 days. Lint per mu 136 pounds. Talk about the following aspects of experience. First, the characteristics of wheat growth and development after (a) shortened growth period. After the whole wheat shortened the whole growth period, which is unfavorable factors for high yield, but after wheat stubble also has many advantages. Mainly wheat early flowering high temperature, to avoid the seedling cold injury, seedling disease is also lighter, easy to seedlings. This test a few
