一、不同根系作物施肥1、直(深)根系作物。如花生、大豆、棉花、青椒、马铃薯等作物,根系集中分布区呈倒锥体。要实行开沟施肥,沟深15厘米,施肥后合土起垄。机械起垄、施肥、播种,要把施肥犁调整到比播种犁深5~10厘米。2、直(浅)根系作物。如架豆角、黄瓜、甜瓜、西瓜、西红柿、大白菜等作物。直根下扎弱势,侧根发达,根系集中分布区呈盘状。播种行两侧各10厘米、深10厘米耕层是高效施肥区。要实行带
First, different root crop fertilization 1, straight (deep) root crops. Such as peanuts, soybeans, cotton, green peppers, potatoes and other crops, the root distribution area was inverted cones. To implement ditching and fertilization, furrow 15 cm deep, fertilization after the ridge ridge. Mechanical ridge, fertilization, sowing, fertilization should be adjusted to the plow sowing depth of 5 to 10 cm. 2, straight (shallow) root crops. Such as rack bean, cucumber, melon, watermelon, tomatoes, cabbage and other crops. Straight under the bar under the weak, well-developed lateral root distribution was disc-shaped distribution. Sowing lines on both sides of the 10 cm, 10 cm deep plow layer is efficient fertilizer. To implement the band
