华北农业科学研究所去年为开辟肥源,曾研究出高温通气堆肥法,这种堆肥法是用马粪来做高温纤维分解菌的接种剂,但在推广工作上,因为农村马粪不足,遭到了一些困难。其后,刘守初、赵质培同志曾研究用马粪培养液的办法接种(详见本刊上期“用马粪培养液接种制造高温堆肥”一文),但在培养方法上,因为需要炉灶等培养和保温设备.在农村推广仍有困难,最近华北农研所河北农村工作组马复祥、林荣洸等同志,在各方支持及刘守初同志协助下,于衡水农场试验利用堆肥坑发热阶段的温度来培养马粪液,已基本成功。这是一种无特需殊设备,利用堆肥坑内高温性细菌所发生的热能来培养它自己的办法,简单易行,人人都可掌握。其具体操作如下:在用高温通气坑堆肥时,另备旧煤油桶一个,放2斤骡马粪,加入冷水20斤,搅拌均匀。当坑内堆积至7成满时,把桶放入,继续堆积,最后将桶埋入坑内;或桶身在坑内,桶口露天用木片及(?)覆盖,与堆肥坑覆土面平。由于堆肥坑发热的作用,前者经6—8天,后者经4—6天,桶内马粪即培养成为马粪培养液。用这样的马粪培养液20斤可以沤烂1,000斤玉米秆(如直接用骡马粪需200斤)。一般情况可采用开口培养方法,特殊情况(如冬季)可采用闭口培养法。这一试验的成功,在生产上意义很大。同时又一次说明,农业科学工作者只有深入农村,结合生产实践之后,才能更好地为人民服务。下面是马复祥、林荣洸同志进行这一工作的简单报告。 North China Institute of Agricultural Sciences last year to open source of fertilizers, has developed a high-temperature ventilation compost method, this compost method is to use horse manure to do high temperature fiber decomposing bacteria inoculant, but in the promotion work, because of insufficient horse manure in rural areas, was To some difficulties. Since then, Liu Shouchu and Comrade Zhao Zipei have studied the use of horse manure culture solution inoculation (see the issue of “horse manure culture medium inoculation of high temperature composting ” article), but in the cultivation methods, because of the need for stoves and other culture And insulation equipment in rural areas still difficult to promote the recent North China Agricultural Research Institute Hebei Rural Working Group Ma Fuxiang, Lin Rongtao and other comrades, with the support of all parties and Comrade Liu Shouchu, Yu Hengshui farm trial using the temperature of the compost pit heat phase to Training horse manure has been basically successful. This is a special equipment without special equipment, the use of heat in the composting pit of high temperature bacteria to develop its own way, easy, everyone can grasp. The specific operation is as follows: In the use of high-temperature ventilation pit compost, the other an old kerosene barrels, put 2 pounds Mu mu manure, add cold water 20 pounds, stir. When the piles into the pits to 7 percent full, the bucket into, continue to accumulate, and finally barrel buried in the pit; or barrel in the pit, bucket mouth open with wood and (?) Cover, and compost pit cover level. Due to the compost pit fever, the former after 6-8 days, the latter after 4-6 days, the barrel of horse manure that is cultured into a horse manure culture solution. With such a horse manure culture liquid 20 pounds can suck 1,000 pounds of corn stalks (such as the direct use mule horse manure need 200 pounds). The general situation can be open culture methods, special circumstances (such as winter) can be closed culture method. The success of this experiment, in the production of great significance. At the same time, it shows again that only after agricultural scientists go deep into the countryside and combine production practices can they serve their people better. The following is a simple report by Comrade Ma Fulin and Comrade Lin Rong-chung on this task.
