一、以增温保墒为重点的早春管理一般情况下,早春的温度和水分是影响冬小麦返青生长的一对主要矛盾。春季雨雪后或返浆后水分充足的麦田,由于水的热容量大,土壤升温慢会影响返青生长;干旱麦田水分不足也会影响冬小麦返青生长。因此,早春管理要抓住主要矛盾,协调温度与水分的关系,增温保墒,促进冬小麦早发快长。1、及时锄划,松土保墒在土壤解冻、表层土壤水分适当下渗或蒸发、人能够下地时,要及时进行麦田锄划。通过锄划切断表层土壤毛细管、减少表面蒸发,可以保住下层土壤水分。还可以使表土层疏松,有利于吸收太阳辐射,提高地温,促进返青。对于冬前生长旺,田间有枯死叶片的,可用耙子顺麦垄搂麦,将冻干麦叶、压住麦苗的坷垃或其他覆盖物搂 First, to focus on the warming of soil moisture Pre-spring Management Under normal circumstances, the early spring temperature and moisture are the main contradictions affecting the growth of winter wheat turning green. Due to the large heat capacity of the water, slowly warming the soil will affect the growth of greening in wheat field after spring rain or snow or after returning to the paddy water. Insufficient water in dry wheat fields will also affect the growth of winter wheat. Therefore, early spring management should seize the major contradictions, coordinate the relationship between temperature and moisture, warming soil moisture, promote the early onset of winter wheat faster. 1, timely hoe draw, soil moisture soil thawing in the soil, surface soil moisture infiltration or evaporation appropriate, people can go to the ground, to promptly wheat field hoe draw. Through the hoe cut cut off the surface of the soil capillary tube to reduce surface evaporation, you can keep the underlying soil moisture. Can also make the topsoil loose, is conducive to absorbing solar radiation, improve ground temperature and promote greening. For the growth of winter before wither, withered leaves in the field, the rake can be used Shun wheat ridge hug wheat, lyophilized wheat leaf, pressed wheat germ or other cover bu hu rub
