为了摸索马铃薯高产规律,一九七九年我所进行了马铃薯高产栽培试验。共播马铃薯17亩,平均单产6470.6斤,其中7亩,单产达9336.6斤。现初步总结如下: 一、及时整地,多施基肥,改进播种技术是获得高产的基础。试验地地势较平,前茬是油菜地,油菜收割后进行了深秋翻,翌春三月二十九日又用重型缺口耙耙地一遍,为播种创造了良好条件。7亩地平均每亩施入羊粪(加入少量三料过磷酸钙)80斤、马粪2000斤;其余10亩,每亩仅施马粪2000斤左右。 马铃薯是高水肥作物。7亩高额丰产试验田的播种方法是:人工开沟28—30厘米深,沟
In order to explore the law of high yield of potato, I conducted a high-yield potato cultivation experiment in 1979. A total of 17 acres of potato broadcast, the average yield of 6470.6 kg, of which 7 acres, yield of 9336.6 kg. Now preliminary summary is as follows: First, timely site preparation, more base fertilizer, improved sowing technology is the basis for high yield. The topography of the experiment was relatively flat. The stubble was a rapeseed. After the rapeseed was harvested in late autumn, it was raked again with a heavy notch on March 29 to create good conditions for sowing. 7 acres of land per hectare of sheep manure (adding a small amount of three superphosphate) 80 pounds, 2,000 pounds of horse manure; the remaining 10 acres, only 2,000 mu of horse manure per mu. Potato is a high water and fertilizer crop. 7 acres of high yield test field planting methods are: artificial ditches 28-30 cm deep, ditch
