林业能否应用优选法?过去我们一直不能作出回答。在毛主席革命路线指引下,我们开展了群众性的科学实验。经过两年的实践,我们认为不但能够用,而且很有用。一、湿地松种子催芽为了掌握湿地松种子发芽的第一手资料,1974年,我们在5个引种点中,首先用0.618法进行了催芽试验。方法是:以5天(共120小时)为试验范围,先按公式计算出1、2、3、4等4个试验点和对照点共5个试验的催芽时数,分别为74、46、92、28和0小时,然后,用同等数量(每小区100粒)播种,对比
Can forestry apply the law of preference? We have not been able to answer it in the past. Guided by Chairman Mao’s revolutionary line, we conducted a mass scientific experiment. After two years of practice, we think it will not only be useful but also useful. First, the sprouting of the pine seeds To grasp the first-hand information on the sprouting of the pine seeds, we conducted the germination test in 0.618 method among the five introduction points in 1974. The method is as follows: take 5 days (120 hours in total) as the experimental range, calculate the number of germination hours of 4 test points and control points of 1, 2, 3, 4, 92, 28 and 0 hours, then sown with the same amount (100 grains per plot), compared
