夏播番茄的生长期正值高温多雨季节,植株生长弱,病虫为害重,多数地区产量低而不稳.近几年来,通过实践,我们总结出了我县保浇地区的一些增产经验.1.培育壮苗选择排水良好、地势较高、远离春番茄地的土壤育苗.选好地后,按长6米,宽150厘米建苗床,然后每畦施腐熟农家肥30公斤,过磷酸钙1公斤,深翻20厘米,整平后每畦施80—90克多菌灵粉剂.选用耐熟、抗病丰产的823优种,在定植前30—40天播种,我县一般在5月25日左右.播种时种子要用0.1%的高锰酸钾药液
Summer sowing tomato growing season is hot and rainy season, plant growth is weak, pests and diseases are heavy, the output is low and unsteady in most areas.In recent years, through practice, we summed up some yielding experience in our county Bao water. 1. To cultivate strong seedlings Select well-drained, high-lying, far from the tomato seedling nursery soil.After selection, according to the length of 6 meters, 150 cm wide seedbed, and then every Shi Shi rotten manure 30 kg, superphosphate 1 kg, deep turning 20 cm, leveling each applied 80-90 grams of carbendazim powder.Enough selection, resistance to high yield of 823 superior species, planted 30-40 days before planting, my county is generally in May On the 25th or so, seeds should be sowed with 0.1% potassium permanganate solution
