深耕是花生增产的一项有效措施。五十年代以前,其土壤耕作大多沿用旧式畜力耕地和人刨的办法,耕深一般在15厘米以下,对作物增产效果较小。随着机械化水平的提高和深耕机具的改进,机械深耕在农业生产上的作用愈来愈引起人们重视,对此也作了大量的试验研究工作。已有的试验研究表明,花生根系在一定范围内随耕层的加深而扩大伸展范围,总根量显著增多,深耕比浅耕能显著提高花生产量,一般增产20％左右。但已往的试验研
Deep plowing is an effective measure to increase peanut production. Before the 1950s, most of their soil cultivation continued to use old-style livestock and plowed land. The cultivation depth was generally below 15 centimeters and the yield increase was less effective. With the improvement of the mechanization level and the improvement of deep plowing machines, the role of mechanical deep plowing in agricultural production has drawn more and more attention, and a great deal of experimental work has also been done. The existing experimental studies have shown that the peanut root system within a certain range with the deepening of the topsoil to expand the scope of the extension, the total root volume increased significantly, compared with shallow plowing can significantly improve the yield of peanut, the general increase of about 20%. But past experimental research
