1.催芽播种催芽播种是实现抢墒播种。确保全苗的基础,是玉米制种田创高产的重要手段,其增产原因是:①催芽的种子抗逆性强,播种后遇低温也不易粉种。②延长营养生长期,促进穗大、粒多。③早播早成熟,有利于种子自然脱水,避免早霜危害。实践表明,催芽比干种播
1. Germination sowing Germination sowing is to grab moisture sowing. Ensuring the foundation of whole seedlings is an important means of high yield for corn farming. The reason for its increase is as follows: ① The seeds of germination are strong in resistance and can not be easily crushed even after low temperature. ② extend the vegetative growth period, promote spike, grain and more. ③ Early sowing early maturity, is conducive to natural seed dehydration, to avoid the hazards of early frost. Practice shows that germination than dry planting
