本文研究了无铺垫猪粪厩肥和禽肥对土壤肥力和苹果产量的影响,并报道了研究结果。试验分别在列宁农场和基洛夫农场果园进行。前者试验地土壤为淋溶黑钙土,供试品种为金矮生;后者为草原黑钙土,供试品种为金冠。在行间正中开沟施肥,开沟深度为20～25厘米,宽度为40～60厘米。所得结果表明:不论厩肥或禽肥,都明显地提高了土壤中硝酸盐、活性磷和代换性
This paper studied the effects of unplanted pig manure and poultry manures on soil fertility and apple yield, and reported the results. The tests were conducted at Lenin Farm and Kirov Farm Orchard respectively. The former test soil is leaching chernozem, the test varieties of gold dwarf; the latter is the steppe chernozem, the test varieties for the Golden Delicious. In the middle of the row ditching fertilization, ditching depth of 20 to 25 cm, a width of 40 to 60 cm. The results showed that: regardless of manure or poultry manure, were significantly increased soil nitrate, reactive phosphorus and substitution
