关于苗圃地的施肥技术,以往报道颇多,但对如何分层施入,如何控制施基肥深度、施肥量及提高均匀程度,报道却不多,本文就这方面问题,谈一点具体做法。 一、施肥前的准备 (一)基肥准备 育苗单位应根据各自的情况,按照育苗的任务、施肥量及早准备基肥(如厩肥、堆肥、饼肥等),并成堆放置,严加封盖(在野外堆放,要防雨淋、暴晒,要隔10—15天左右翻动一次),以便充分腐熟和防止病虫侵入。对于饼肥需拌入少量细泥,喷入适当水分,再搅拌均匀成堆。 (二)圃地准备 若是冬闲地,应在冬季进行垦翻冻垡(土垡不要敲碎),播种前10—20天结合土壤消毒再翻耕一次,并敲碎土垡。若圃地有苗不能进行冬翻,应在初春苗木起出后,立即抓紧时间进行,数天后再进行第二次翻土碎垡。 二、施基肥方法
Fertilization techniques on the nursery have many reports in the past, but how to control the depth of application of base fertilizer, the amount of fertilizers and the degree of evenness increase are not many reports on how to apply them in layers. This article discusses some specific practices in this respect. I. Preparation before fertilization (a) Preparation of basal fertilizer Breeding units should be based on their own circumstances, in accordance with the task of nursery, the amount of fertilizer as soon as possible to prepare base fertilizer (such as manure, compost, cake, etc.) Piled up in the wild, to prevent rain, exposure, to flip about every 10-15 days), in order to fully decomposed and prevent pests intrusion. For the pie to be mixed with a small amount of fine mud, sprayed into the appropriate water, then stir into piles. (B) garden preparation If the winter fallow, should be done in winter icing freeze 垡 (soil 垡 do not cracked), 10-20 days before sowing the soil disinfection and then plowing and crushing soil 垡. If nursery seedlings can not be carried out in winter turn, seedlings should start early spring, immediately seize the time to carry out a few days later for the second soil broken 垡. Second, the method of basal fertilizer
