白浆土井灌种稻,因白浆层不漏水,可节省灌水成本。但白浆土板结、冷凉,影响水稻的生长发育。为此必须搞好播前整地。 1984年,在向阳川镇福安村,采用深松旋耕、秋翻春旋、原茬旋耕、秋翻春耙(对照)进行对比试验,结果表明,无论是秧苗素质还是产量,均以深松旋耕居首位,其次为秋翻春旋。原茬春旋效果最差(见表)。深松旋耕破坏了白浆层,改善了土壤物理性质,所以增产显著。
White soil well irrigation paddy, because the white pulp layer leaking, irrigation costs can be saved. However, white clay soil knots, cold, affecting the growth and development of rice. To do this must be done before sowing. In 1984, the Fuyang Village of Yangchuan Town was used to carry out comparative experiments with deep-plowing and rotary plowing, spring turning with autumn turning, rotating plowing with original crop rotation and raking with autumn turning spring (control). The results showed that both the quality and the yield of seedlings were subsoiled Rotary first place, followed by autumn turning spring spin. Original crop spring spin the worst (see table). Subsoiling rotary tillage destroyed the white pulp layer, improving the physical properties of the soil, so a significant yield increase.
