棉花膜侧播种,既便于机械作业,又利于回收塑膜以减少对土壤的污染,更重要的是较膜上打孔播种的增产,经济效益突出,因而易于推行.现将我们两年来在焉耆地区的试验结果简报于下.一、试验经过和产量表现1982年,我们进行了两次膜侧播种试验.第一次布置在盐轻土肥的地上,小区行长10米,5行区,行距60厘米,3次重复,于4月29日播种;第二次选在重盐碱地上,
Cotton film seeding, both for mechanical operations, but also conducive to the recovery of plastic film in order to reduce soil pollution, more important than the membrane drilling perfusion increased production, outstanding economic efficiency, and therefore easy to implement now we two years Yanqi A brief summary of the regional test results First, the test through and yield performance In 1982, we conducted two seeding experiments on the membrane side, the first arrangement in the salt light soil on the ground, the district governor 10 meters, 5 line area, spacing 60 cm, three replicates, sowed on April 29; the second selection of salt in the saline soil,
