“密”是农业“八字宪法”的重要环节。密植要合理。种得太稀,每亩苗数少,不能充分利用地力和阳光,影响产量提高;种得太密,既浪费种子,麦苗又过分拥挤,旱薄地长不起来,肥水地造成倒伏减产。到底每亩播几斤才算合理密植?这是一个值得引起各地注意的重要问题。龚文生同志介绍的“五定法”,为确定播种量提供了宝贵经验。要根据品种、地力、播期、管理水平来确定适宜的种植密度。并要精细整地,提高播种质量,防治地下害虫,以提高出苗率和保苗率,在保证合理密植的前提下,尽量节约用种。我们欢迎大家投稿就播种量问题展开讨论。
“Secret” is an important part of the “eight-character constitution” of agriculture. Close planting should be reasonable. Too thin seedlings per acre, can not make full use of fertility and sunlight, affecting the yield increase; species too dense, not only waste seeds, wheat seedlings and overcrowding, drought grow up, fertilizers cause lodging yield. In the end broadcast a few pounds per mu is reasonable and close planting? This is an important issue that deserves attention around. The “Wuding Law” introduced by Comrade Gong Wensheng provided precious experience in determining planting volume. According to species, fertility, sowing date, management level to determine the appropriate planting density. And to fine preparation, improve the quality of planting, control of underground pests, in order to improve the emergence rate and seedling protection rate, under the premise of ensuring a reasonable density, try to save species. We welcome everyone’s contribution to discuss the issue of seeding volume.
