1品种选择选用抗病、早熟、耐寒、结果集中、丰产的品种。培育壮苗的主要技术环节.1苗床准备番茄春早熟栽培的育苗期正值寒冬低温时期,播种时尽量提高地温,可利用加温温室和电热线育苗。利用电热温床育苗时,功率密度为100W/m2,即电热加温线的线间距为10cm可保证在外界气温为-15℃时,苗床内的温度为15℃,番茄秧苗免受冷害、冻害。番茄苗期用无病的大田土,按40%~50%的比例施
Selection of a variety of disease-resistant, precocious, cold-resistant, concentrated results, high yield varieties. Breeding seedlings of the main technical aspects.1 seedbed preparationPowercastle early spring cultivation of nursery period coincides with the winter cold temperature, sowing as much as possible to improve the ground temperature, can be used to heat greenhouses and hotline nursery. The use of electric hotbed nursery, the power density of 100W / m2, that is, heating line spacing of 10cm to ensure that the outside temperature is -15 ℃, the temperature inside the seedbed is 15 ℃, tomato seedlings from chilling injury, frost damage. Tomato seedling disease-free field soil, according to the proportion of 40% to 50%
