番茄可以菜、果兼用,深受市民喜爱。尤其是春番茄,既适宜作夏令菜肴,又是消暑解渴的佳品。在番茄的一生中,需吸收大量的氮磷钾元素和多种微量元素。假若氮磷钾养分供应失调,会直接影响番茄的产量和品质。为了摸索这个问题,我们进行了“春番茄氮磷钾不同配比效应试验”,现小结如下: 一、试验设计根据土壤肥力状况和生产水平,在统一亩施有机质肥料(猪塮)60担的情况下,分设五种化肥处理,三次重复:1.单氮区为亩施碳铵250斤;2.氮磷区为亩施碳铵250斤、过磷酸钙150斤;3.氮钾区为亩施碳铵250斤、氯化钾35斤;4.氮磷钾区为亩施碳铵250斤、过磷酸钙150斤、氯化钾35斤;5.对照区(即无化肥区)。有机质肥料和各种化肥均在移栽前深施入土,以后不施任何肥料。
Tomato can be food, fruit and use, by the public favorite. In particular, spring tomato, both suitable for summer dishes, but also refreshing thirst quencher’s share. In tomato’s life, need to absorb a large number of nitrogen, phosphorus and potassium elements and a variety of trace elements. If the NPK nutrient supply disorders, it will directly affect the yield and quality of tomatoes. In order to explore this issue, we conducted a “spring tomato N, P and K different proportioning effect test”, are summarized as follows: First, the experimental design According to soil fertility and production levels, in a unified organic fertilizers (pig iron) Under the circumstances, divided into five kinds of fertilizer treatment, three repetitions: 1. Nitrogen Monarch ammonium bicarbonate 250 kg; 2. Nitrogen and phosphorus area of 250 kg of ammonium bicarbonate, superphosphate 150 kg; 3. Nitrogen potassium zone is Mu of ammonium bicarbonate 250 kg, 35 kg of potassium chloride; 4. NPK area of 250 kg of ammonium bicarbonate, superphosphate 150 kg, 35 kg of potassium chloride; 5. Control (ie no fertilizer area). Organic fertilizers and various fertilizers are deeply applied to soil before transplanting, and no fertilizers are applied thereafter.
