北疆特早熟棉区,棉花栽培技术措施中,密植是增产的关键之一,特别对增产霜前花,效果更好。据农七师小拐农埸调查,棉田密度4,000—10,000株的范围内,密度愈大,产量愈高:亩保苗4,000株,单产籽棉151斤;亩保苗10,458株,单产籽棉350斤。但密植也有一定的限度,超过这个限度,产量又随密度的提高而渐减。因此,研究棍花的种植密度,确定当地适当的密植程度,对提高棉花单产,具有重要的意义。
Especially in the northern part of the cotton precocious cotton area, cotton cultivation techniques, planting density is one of the key to yield, especially for the pre-production of frost, the effect is better. According to a survey of farmers in Shijiazhuang Agricultural Bureau, the density of cotton fields is 4,000-10,000. The higher the density, the higher the yield: 4,000 mu of seedling and 151 kg of seed cotton; 10,458 mu of seedling and 350 kg of seed cotton per mu. However, close planting has a certain limit, beyond this limit, the yield decreases with increasing density. Therefore, it is of great significance to study the planting density of the stick flower and determine the suitable density of the local planting, which will improve the cotton yield.
