一、选用优良品种.目前我市生产上大面积推广的有高抗烟草花叶病毒的早熟优良品种渝抗二号、渝抗三号;高抗烟草花叶病毒和枯萎病而又适于春秋两用的早熟优良品种渝抗四号。二、土壤地势选择。番茄栽培土应选择地势高燥、阳光充足、土层深厚、疏松肥沃、排水良好及酸碱度适宜(pH6.5—7)的壤土;多年未种过茄科(茄子、辣椒、马铃薯、烟叶)作物的土壤,或地势较高,排水性能较好的水稻田种植番茄。三、整地作厢施基肥。①整地:定植前20—40天深耕坑土,②作厢:用早熟品种,1.33米开厢(包一沟)为宜。重庆及川东南地区5—6月为全年降雨高峰期,不利番茄生长发育,因此,以深沟高厢栽培最好。③施足基肥:基肥以有机肥为主,
First, the selection of fine varieties. At present, the city’s production of a large area to promote the anti-tobacco mosaic virus resistant varieties of good early Yuzheng 2, Yukang 3; high resistance to tobacco mosaic virus and Fusarium but suitable for the Spring and Autumn Dual-use varieties of good early Yu-resistant on the 4th. Second, the topography of the soil. Tomato cultivated soils should be high-dry, sunny, deep soil, loose and fertile, well drained and suitable pH (pH6.5-7) loam; for many years without Solanaceae (eggplant, peppers, potatoes, tobacco) crops Of the soil, or higher terrain, drainage performance better paddy fields planted tomatoes. Third, soil preparation for base fertilizer. ① site preparation: 20-40 days before planting deep pit soil, ② for the box: with precocious varieties, 1.33 m box (package a ditch) is appropriate. Chongqing and southeast of Sichuan from May to June for the annual rainfall peak, unfavorable tomato growth and development, therefore, to cultivate the best of deep groove high carriage. ③ Shizujifei: based on organic fertilizer based on basal fertilizer,
