北疆早春宜耕期短,多干风,尤其在较粘重的士壤上要获得早苗全苗,保墒是一个中心问题.棉花地的墒度要求是,表土2.5-3公分为干土时就立即进行春灌.经验证明,春灌并不降低地温、同时使幼苗早出士,生长快.这是获得丰收的一关.此外,还应注意采取如下措施:一、细致整地1.经过秋耕施基肥的粘土地,早春应耙地保墒.当雪融时(日化夜冻)立即组织人拉耱,耱碎土块.在人为能进地时,即行点片保墒,做到寸土必保.防止保墒工作进行过早,而使地面形成泥条.土壤过于粘重,地表板结,之字耙耙地不起作用时,可组织轻型圆片耙,调
In the early spring of northern Xinjiang, the shortening period and more wind, especially in the more sticky soil to obtain seedling seedlings, preserving soil moisture is a central issue.The requirement of moisture content of cotton land is that topsoil 2.5-3 cm is dry soil Spring irrigation immediately.Experience has shown that spring irrigation does not reduce the ground temperature, while the early seedlings to grow, grow fast.This is a bumper harvest.In addition, we should also take the following measures: First, careful site preparation 1. After autumn cultivation Basal fertilizer in the clay, early spring should rake moisture. When the snow melts (daily night freeze) immediately organize people pull 耱, 耱 broken clods. In artificially into the ground, that is, point pieces of soil moisture, so that soil must be guaranteed. Prevent soil moisture premature work, leaving the formation of mud on the ground. Soil is too sticky, the surface plate knot, rake harrow word does not work, you can organize light disc rake, tune
