根据农牧渔业部农业局土肥处和北京农业大学的安排,今年对甜瓜施用中、低分子量腐殖酸混合锌肥(以下简称腐殖酸)进行了大田试验示范。参加试验示范的单位有哈密地区农业技术开发中心,哈密、昌吉市和鄯善、阜康、沙湾县农技站,哈密市南湖、花园、大泉湾乡农技站。试验示范面积1170亩,其中哈密820亩,鄯善县100亩,阜康县150亩,昌吉市和沙湾县各50亩。肥料用量一般喷一次亩用腐殖酸17克,锌肥15克。施肥方法喷施。现将试验示范结果简结如下: 一、甜瓜喷施腐殖酸能促进植株生长发育 甜瓜喷施中、低分子量腐殖酸可增强植株体内生理代谢;喷施腐殖酸后,第三天光合强度及生理代谢活动显著提高,喷施的较未喷施的生长旺盛,叶片明显增厚,叶色变深,茎蔓变粗长长。哈密地区开发中心和哈
According to the Ministry of Agriculture, Animal Husbandry and Fisheries Department of Agriculture Fertilizer Office and Beijing Agricultural University, this year on the application of melon, medium and low molecular weight humic acid mixed zinc fertilizer (hereinafter referred to as humic acid) were field experiments. Units participating in the pilot demonstration include Hami Agricultural Technology Development Center, Hami, Changji City and Shanshan, Fukang and Shawan Agricultural Technology Stations, Hami Nanhu, Garden and Daquanwan Township Agricultural Technology Station. Demonstration area of 1170 mu, of which 820 acres of Hami, Shanshan County, 100 acres, 150 acres of Fukang County, Changji City and Shawan 50 acres. The amount of fertilizer generally spray a humic acid with 17 grams, 15 grams of zinc fertilizer. Spraying fertilization methods. Now the demonstration results are summarized as follows: First, the melon spraying humic acid can promote plant growth and development Melon spraying, low molecular weight humic acid can enhance the physiological metabolism of plants; spraying humic acid, the third day of photosynthesis The intensity and physiological metabolic activities were significantly increased. Compared with the unirradiated ones, the vigor of the spraying was vigorous, the leaves were obviously thickened, the leaf color became deeper and the stems became thicker and longer.
