二、株行距配置方式问题:新疆现有的主要棉花品种为108—Φ、611—Б及 KK—1543等,在中等肥沃土壤、地下水位较低(1.5—2米以下)、坡度不大的棉田上,株行距配置方式以50×50×3的产量最高。这种方式适宜用条播横向间苗方法进行方形窝冲。60×60×3的方式由于株数减少很多,产量降低。采用50×50×3的方式,如果没有20—22厘米笮轮胎的中耕拖拉机时,可以在播种时为宽轮胎(30厘米的)拖拉机留下60厘米宽行距的走道,其余仍为50厘米。采用60×45×3或60×50×3长方形窝种的方式,虽可争取一定的密度,但不便于用一台拖拉机同时进行纵横中耕工作,需要改换轮距及中耕锄齿的安装。正方形窝种可以固定一台中耕拖拉机实行包地包工包产的专责制。
Second, the row spacing allocation problem: Xinjiang’s existing main varieties of cotton 108-Φ, 611-Б and KK-1543, etc., in moderately fertile soil, groundwater level is low (1.5-2 meters below), the slope is not large On the cotton field, the spacing between rows and rows is 50 × 50 × 3. This method is suitable for the use of horizontal seedlings square barbed squat method. 60 × 60 × 3 way due to a significant reduction in the number of plants to reduce production. With a 50x50x3 approach, without a cultivating tractor with 20-22 cm 笮 tires, a 60 cm wide walkway can be left for a wide-bodied (30 cm) tractor when sowing, leaving the remaining 50 cm. The use of 60 × 45 × 3 or 60 × 50 × 3 rectangular nesting method, although for a certain density, but not easy to use a tractor at the same time vertical and horizontal work, need to change the wheelbase and cultivator hoe tooth installation. Square nest can cultivate a cultivator tractor to implement the system of contracting and contracting.
