棉花工厂育苗无土移栽密度在新乡市的筛选

The Cotton Density Trial of Transplanting Seedling Without Soil in Xinxiang

3年生产试验结果表明：棉花工厂育苗无土移栽技术适合新乡市的生产条件。其豫杂35号的适宜种植密度为每公顷23294～31312株，在此范围内可获得98％以上的理论产量。

The cotton density trial of transplanting seedling without soil which are grown in the factory were conduct for three times in xinxiang. The three years＇ outcomes indicated that there were optimum planting conditions for transplanting seedling without soil which are grown in the factory in Xinxiang. The optical planting density of yuza 35 is 23294-31312 plants per hectare in the way of transplanting seedling without soil. The 98 percent of theory yield would be gained if the cotton was plant in the optimum range.
