一、精少量播种的好处: 1.省种又增产。实践证明,每亩可节省种子7～12公斤,可增产小麦40公斤左右。原因是在水肥地力良好的条件下,较好地解决了群体与个体的矛盾。播量减小后,群体较小,但疏密合理,改善了个体的光照、营养条件,因而分蘖充分,生长健壮,根系发达,成穗率高,单株穗多,穗大,籽粒饱满,所以能高产。 2.促进机械化的发展。精少量播种要求深耕,同时对播种质量、精度要求高,必须进行机耕、机播,这对农业机械化的发展是个很大的促进。 3.省工省力,减轻劳动强度。由于采取机耕、机播,可以大大提高工作效率,同时也减轻了农民的劳动强度。
First, the benefits of fine sowing: 1 provincial species and increase production. Practice has proved that per acre can save seeds 7 to 12 kg, 40 kg of wheat can be increased yield. The reason is that under the favorable conditions of water and fertilizer, the contradiction between groups and individuals is well solved. Sowing reduced, the smaller population, but the density is reasonable and improve the individual light and nutrition conditions, and thus fully tiller, robust growth, root system developed into a high rate of spike per panicle, spike, full grain, So can be high yield. 2. To promote the development of mechanization. Fine sowing requires deep plowing, while the sowing quality, high precision, must be plowed, machine sowing, which is the development of agricultural mechanization is a great promotion. 3. Labor saving, reduce labor intensity. As a result of tillage, machine sowing, can greatly improve work efficiency, but also reduce the labor intensity of farmers.
