在一个自然区域内,每种作物都有它的最佳播种期。在这个时期里播种,就更容易做到出苗齐、长的壮,为获得好收成打下良好基础,如推迟播种,作物易贪青晚熟,产量降低,甚至会遇严重的低温冷害而绝收。而过早下种,有的作物会因低温多湿而粉种、坏种,造成出苗不全、不齐,有的则因埋种时间过长,长出的苗不壮不旺,同样导致减产。过去我省习惯晚种,加上播种技术落后,人均占
Within a natural area, each crop has its best seeding period. Sowing seeds during this period will make it easier for them to emerge and grow stronger. They will lay a good foundation for obtaining good yields, such as delaying sowing crops, being susceptible to late blooming and crop production, reducing yields, and even receiving serious chilling injury. The premature species, some crops will be due to low temperature and humidity and powder, bad species, resulting in incomplete seedlings, missing, while others are buried for a long time to grow the seedling not strong, also led to cut. In the past, I was accustomed to the late species of agriculture, with sowing technology backward, per capita
