在茄果类中,辣椒形成单位产量对氮、磷、钾、钙等营养元素需要量较多,是喜肥蔬菜。辣椒又基本上是两列侧根,根条数目少,在土壤中分布较浅,根系不发达,吸收能力较差。为了探讨喷肥的增产作用,我们进行了辣椒叶面喷施金邦1号(含氮、磷、钾、钙、镁等多种营养元素)、磷酸二氢钾、有水氯化钙的对比试验。一、材料与方法试验于1989～1990年在沈阳农业大学园艺系试验场进行。1989年的试验地块连续8年(含试验当年),每年每亩施入腐熟猪粪5立方米左右,土壤肥力较低,1990年的试验地块与上年试验地相邻,但它是连续7年塑料大棚栽
In solanaceous plants, the production of pepper per unit of nitrogen, phosphorus, potassium, calcium and other nutrients require more, are hi fat vegetables. Pepper is basically two rows of lateral roots, the root of the number of small, shallow distribution in the soil, root system underdeveloped, poor absorption. In order to explore the effect of fertilization on yield increase, we carried out the contrast test on the foliar spray of Jinbang No. 1 (including nitrogen, phosphorus, potassium, calcium, magnesium and other nutrients), potassium dihydrogen phosphate and calcium chloride hydrate. First, the material and method test in 1989 to 1990 in Shenyang Agricultural University Horticulture Department test site. In 1989, the plots of plots for 8 consecutive years (including the test year) were applied with about 5 cubic meters of decomposed pig manure per mu per year, resulting in low soil fertility. The plot for the trial in 1990 was adjacent to that of the previous year but it was 7 consecutive years of plastic shed planted
