近年来,市郊菜区在施肥上普遍存在偏氮肥、轻磷肥、忽视钾肥的现象,造成氮肥浪费,地力平衡失调,影响番茄的产量和质量。为了平衡地力,使番茄更好生育,1986年春我们根据番茄吸肥特点及养分分配规律研制了“番茄专用混肥”(以下简称专用肥),并与等氮量的进口复肥、当地习惯肥进行肥效比较试验。现将试验结果简述如下:
In recent years, suburban vegetable areas in the fertilization of the widespread of partial nitrogen, phosphorus fertilizer, ignoring the phenomenon of potassium, resulting in nitrogen waste, imbalance in soil fertility, affecting the yield and quality of tomatoes. In order to balance the fertility, so that better tomato growth, the spring of 1986 we based on tomato absorption characteristics and nutrient allocation law developed a “special tomato fertilizer” (hereinafter referred to as special fertilizer), and with the import of nitrogen compound fertilizer, the local custom fertilizer Fertilizer comparison test. The test results are summarized as follows:
