| 摘 要： | 研究表明:新老菜区间土壤全量及速效养分已存在较大差异;不施肥时,速效N是本地区第一缺乏的养分,而在当前农民施肥习惯下速效钾是第一应补充的养分;高产条件下,本地区每生产1000kg西红柿,耕层土壤中平均需速效养分(土壤+施入)N6.34kg、P2O52.65kg、k2O5.06kg.只有N、P、K三素配施,才有利于西红柿可持续高产高效栽培。 |

| Abstract: | The investigation revealed that the whole nutrient and instant nutrient of soil have clear difference between old and new vegetable field .It showed that the fast-releasing nitride is the most defective nutrient in the circumstance without applying fertilizer. But instant potassium should be the first complement at present cultural practices. Cultivated soil need to be applied instant N 6.34Kg,P2O52.65Kg,K2O5.06Kg on average to produce 1000 kilograms tomato at a high productivity. Only nitrogen, phosphorus and potassium used in coordinated system can get a sustaining, productive and efficient tomato cultigens in this area. |
