钾是作物生长不可缺少的营养元素,但是由于农民施肥习惯及市场欠缺钾肥,生产上追施氮肥多于钾肥,致使很多菜田缺钾,蔬菜矮小,叶缘发干,果实发育不良,抗旱、抗寒和抗病功能明显减退。1996年,我们将钾宝、宝力丰等钾肥在蔬菜上施用,收到很好的效果。 一、春花菜 品种为雪丰,耕地前亩施10kg钾宝作基肥,撒后耕地,与土混合均匀,整平作畦。并在团棵期、初花期喷施0.5％钾宝液。喷施钾肥的植株挺立健壮,叶色浓绿而叶片厚,花球生长快,坚实而洁白,亩产量比对照高16.7％,增收5159元。 二、番茄 品种为中蔬5号,秧苗期、现花期、初果期和果实膨大期各喷施0.5％钾宝液。喷后观察,施钾肥的植株坚硬,叶浓绿,坐果多,果实膨大快,果色美,品质佳,抗病,抗寒,产量比对照高出17.2％,每亩增收300多元。 三、芹菜 Potassium is an indispensable nutrient element for crop growth. However, due to farmers’ fertilization practices and the lack of potash fertilizer on the market, more nitrogenous fertilizer is produced than on potash fertilizer. As a result, many vegetable fields have potassium deficiencies, short vegetables, dry hair foliage, poor fruit development, drought resistance, Cold and disease resistance significantly reduced. In 1996, we applied potassium potash, Baoli abundance and other potash on vegetables and received very good results. First, the varieties of spring cauliflower Xuefeng, acre before planting arable land 10kg potassium Po for basal fertilizer, sprinkle arable land, and soil mixed evenly, flattened 畦. And in the group of trees, early flowering spray 0.5% potassium Bao liquid. Plants sprayed with potash stand tall and strong, dark green leaves and thick leaves, flower bulbs grow fast, solid and white, yield 16.7% higher than the control, an increase of 5159 yuan. Second, the tomato varieties for the No. 5 in the vegetable, seedling stage, the current flowering period, early fruit and fruit enlargement of each spray 0.5% potassium Bao liquid. After sprayed, the plants which applied K fertilizer were hard, the leaves were thick green, the fruit was more, the fruit swelled fast, the fruit was beautiful, the quality was good, the disease resistance and the cold resistance were higher than the control by 17.2% and the yield per mu was more than 300 yuan.
