庭院种植番茄,往往枝蔓长得好,果实结的少,加之病虫为害,产量较低。针对庭院存在的问题,我们于1988～1990年连续三年进行了试验研究,总结出主要栽培技术,供庭院栽培番茄者参考。一、补施磷钾肥庭院番茄连作常因土壤内的氮、磷、钾三要素含量比例不协调,导致产量显著下降。要实现连作不减产,必须对土壤补施磷钾肥,并增施微肥。在耕地时,亩产一万斤的地块,除施足农家肥外,还应增施过磷酸钙50～60公斤、硫酸钾15～20公斤、碳铵40～50公斤,并施锌和硼各2～3公斤。多年的生产实践证明,采用这种施肥比例,不仅 To grow tomatoes in the courtyard, branches tend to grow well, fruit knot less, combined with pests and diseases, the yield is lower. In view of the existing problems in the courtyard, we carried out experimental studies for three consecutive years from 1988 to 1990, and summarized the main cultivation techniques for the reference of garden cultivated tomatoes. First, the supplement of phosphorus and potassium Garden tomato even often due to soil nitrogen, phosphorus and potassium content of the three elements are not coordinated, resulting in a significant decline in production. To achieve continuous cropping without reduction, it is necessary to supplement the soil with phosphorus and potassium fertilizers, and increase the application of trace fertilizers. In the arable land, a kilogram of land per mu yield, in addition to full foot manure, should also be applied over 50 to 60 kilograms of calcium phosphate, potassium sulfate 15 to 20 kg, 40 to 50 kg of ammonium bicarbonate and zinc and Boron 2 to 3 kg each. Years of production practice has proved that the use of such fertilization ratio, not only
