玉米芯来源广,代价低,理论上生物学效率也较高,但它难以粉碎,不宜袋栽、床栽,实践上难以采用,笔者多次试验,采用整玉米芯墙栽,取得良好效果,技术要点如下: 1.墙栽时墙的厚度,以40cm左右即两个玉米芯长度为宜。玉米芯长短不同,但墙的外面要较平整,参差部分留在墙内。 2.每平摆一层玉米芯,加一层填充料(锯末、碎秸秆等),菌种播在填充料上。这象用砖垒墙要用灰浆一样,使玉米芯之间不留缝隙,利于菌丝生长。 3.由于玉米芯含碳较多,含氮相对较少,所以填充料中要适当加一点尿素、麸皮等含氮较多的物质。 4.由于玉米芯含糖较多(碳水化合物),pH值易偏酸,所以填充料中要适当多加些石灰粉。
Corncob wide source, the price is low, the theoretical biological efficiency is also high, but it is difficult to crush, not bagging, bed planting, difficult to use in practice, the author repeated tests, the entire corncob wall planted, and achieved good results, Technical points are as follows: 1 wall when the wall thickness to 40cm or so that is appropriate length of two corn cobs. The length of the corncob is different, but the outside of the wall should be flat and the mixed part will remain in the wall. 2. Put a layer of corn cob per square, add a layer of filler (sawdust, broken straw, etc.), bacteria sow the filler. This is like using masonry walls with mortar, leaving no gap between the corncob, conducive to mycelium growth. 3. Because corn cob more carbon, nitrogen is relatively small, so the filler should be appropriate to add a little urea, bran and other substances containing more nitrogen. 4 due to more sugary corncob (carbohydrates), pH is easy to acid, so the filler should be more appropriate to add some lime powder.
