麦田盖肥最好在小雪以后,麦苗停止生长后的十来天内进行。盖得过早,气温还高,容易把麦苗闷黄或烂苗。若盖的太晚,起不到防寒保苗的作用。盖肥也不宜过厚,一般盖1.7厘米就可以了。盖肥时要先将腐熟的肥料用钉耙捣碎,运到麦田均匀撒开。每亩3立方米左右为宜。撒开后,最好用竹扒子顺垄背把肥料集中盖在麦垄上,以增加保暖效果。来年开春小麦返青时,再用竹扒子顺垄轻轻把肥料搂在垄背上,使麦苗充分得到阳光,待叶片返绿后,便可浇水追肥。据小麦种植专业户试验,冬季盖肥的小麦比不盖肥的小麦,分蘖节处日平均地温高0.5～1℃。开春扒肥清垄后,越冬叶片可直接进行光合作用,提早5-7天进入单棱期,延长了小麦穗分化的时间,为争取小麦穗大穗多创造了有利的条件。
Wheat field cover fertilizer is best after the snow, wheat seedlings stop growing within ten days after. Cover too early, the temperature is still high, easy to barley yellow stuffy or rotten seedlings. If the lid is too late to play the role of cold seedlings. Fat cover should not be too thick, generally cover 1.7 cm on it. Cover fertilizer when the first compost fertilizer with rake mashed, shipped to the wheat field spread evenly. 3 cubic meters per mu is appropriate. Sprinkle, it is best to use bamboo Pazi Shun ridge fertilizer to focus on the wheat ridge, in order to increase the thermal effect. In the spring of next spring, when the wheat is turned green, the bamboo razor strips along the ridge gently pull the fertilizer around the ridge of the ridge, so that the wheat seedlings are fully sunshine. After the leaves are green, the water can be topdressing. According to the test of wheat planting professional households, wheat covered with winter fertilizer was 0.5-1 ℃ higher than the daily average temperature of tiller knuckle than non-fattened wheat. In the spring, after the ridge is cleared, the overwintering leaves can directly conduct photosynthesis, entering the single-ridge stage 5-7 days earlier, extending the time of wheat spike differentiation and creating favorable conditions for striving for the spike of wheat spike.
