缺苗是造成玉米减产的原因之一,据调查一般缺苗20%左右,可减产一成或稍多。为了保全苗,过去常采用催芽补种或雨后拔苗移栽的方法。实践证明如此补种或补栽的苗子常是株矮、杆细、叶黄、穗小、成熟晚,收获时多数还处在灌浆中期,有的成为空杆,落个费工费时收把柴,所以,农民说:“补苗如补草”,实际上不愿干。尤其夏玉米缺苗往往达20—30%,造成严重减产。针对这一问题我们试验了“带土移栽”法,实践证明,效果较好。因为方法简单易
Lack of seedlings is one of the reasons for the reduction of corn production. According to the survey, about 20% of the total lack of seedlings can be reduced by 10% or more. In order to protect the seedlings, the past often used to promote seedling replanting or transplanting methods. Practice has proved that replanting or replanting of the seedlings often plant dwarf, thin rod, yellow leaves, spikelets, mature late, most of the harvest is still in the middle of filling, and some became empty bar, fall fees a fee to collect the firewood Therefore, the farmer said: “make up seedlings such as grass,” and actually do not want to do it. In particular, summer maize lack of seedlings often reach 20-30%, causing serious cuts. In response to this problem we tested the “soil with transplanting method”, the practice has proved that the effect is better. Because the method is simple and easy
