为了进一步探讨用养结合创高产的轮作措施,我们总结应用了花生产区粮油水旱轮作改良利用红壤的群众经验,在弥勒县良种场进行粮油水旱轮作并在两茬间隙中插入短期绿肥太阳麻和红萍的试验。轮作周期的安排:第一年花生—油菜;第二年水稻—小麦(或蚕豆)。在油菜后茬插入太阳麻或红萍,试验情况和初步结果如下:一、油菜茬太阳麻——油菜收后翻犁整地,于4月24日撒播太阳麻。每亩播量10市斤,播后用耙复土,透灌出苗水。六天出苗,齐苗后每10天给水一次。5月29日压青(生长32天),株高35公分,亩收鲜绿肥599.4斤。沤青5天栽秧。二、假滥田养萍——油菜收后放水泡田犁耙整平,于4月16日放萍,每亩约放萍种200斤。5月20日人工倒萍栽秧,亩得萍肥492.1斤。
In order to further explore the combination of planting and high-yielding crop rotation, we summed up the application of the mass production of grain and oil rotation and improvement of the use of red soil in the population experience in Maitreya County, grain and oil fields rotation and crop rotation in the intermission of two short stubble green manure Ma and Hongping test. Rotational cycle arrangements: first year peanut - rape; second year rice - wheat (or broad bean). In the rape stubble into the sun hemp or red duckweed, the test results and the preliminary results are as follows: First, the rape stubble Sun Ma - rape harvest plowing site preparation, broadcast on April 24 Sun Ma. Seeding rate of 10 kg per mu, after sowing with soil, soil, pour irrigation water. Six days after emergence, Qi Miao once every 10 days water. May 29 pressure green (growth of 32 days), plant height of 35 cm, 599.4 kg of fresh green manure received. Ching green 5 days planted seedlings. Second, the overdue field sprinkle Ping - rape after the harvest water soaked field rake leveling, put the duck on April 16, about 200 kg per acre Ping. May 20 artificial inverted transplanting seedlings, acres of Pingfei 492.1 pounds.
