作者于省农业科学院作物所,以容易木质化的檉麻作旱地綠肥,在江淮地区的自然条件下,观察其在土壤中的腐烂速度、土壤养份的变化、作物吸收情况及其增产效果。方法是,1961年9月27日掩青蕾期的檉麻,每亩二千斤,10月3日播种小麦(品种为吉利麦)。試驗証明,檉麻虽纤维較多,本質化程度較大,但以蕾期的檉麻掩青作小麦基肥,在气温较高(摄氏十一至二十二度)及土壤水份較充足(18—24%左右)的条件下,分解是很快的,而分解最快是在掩青后一个月以内,据10月25日測定,这时檉麻残余体只剩26.75%,这一点也可从土壤(八至十八厘米)中硝态氮含量的增长上看出,同日测定,掩青的硝态氮含量为十点八六四毫克/一百
The authors from the Institute of Crop Sciences of the Academy of Agricultural Sciences, in order to easily lignification of the hemp as a green manure fertilizer, in the Jianghuai region under natural conditions, observed in the soil rot, soil nutrient changes, crop absorption and yield increase. Method is, September 27, 1961 to cover the bud of the bud period, two kilograms per acre, October 3 sowing wheat (varieties of auspicious wheat). Experiments show that although the fiber is more fibrous callus, a greater degree of substantive nature, but to bud budding malaria green wheat base fertilizer, the higher the temperature (Celsius eleven to twenty-two degrees) and soil moisture is more adequate 18-24%) under the conditions, the decomposition is fast, but the decomposition is the fastest in less than a month after the cover, according to October 25 determination, when the residue is only 26.75% residual sisal, which is also Can be seen from the soil (eight to eighteen centimeters) in the nitrate content of the growth seen on the same day determination, cover the green nitrate content of 10.884 mg / 100
