一、提高透光性,调节温湿度。大棚南北延长,能使棚内光照分布均匀。采用防尘无滴膜能增加棚内的透光率。棚口处要设风障或张挂塑料膜。大棚内空气湿度大,茄苗定植后易发病。采用地膜覆盖,膜下沟灌,适时放风,能调节棚内湿度。二、施足底肥,深耕细作。春茬茄子生长结果期长,吸肥量大。定植前每亩施消毒猪鸡粪6～7方,并掺施硫酸钾25公斤,深耕20厘米以上,使土壤形成良好的水肥气热性状。定植前最好再换上新膜。三、培育壮苗,适时嫁接。嫁接换根栽培是春茬茄子克服连作障碍和黄萎病的关键性技术。砧木可选用赤茄或CRP,接穗可选用亚安绿茄或糙青茄,做到年前适时播种,增育壮苗。当砧木与接穗都长
First, improve light transmission, adjust the temperature and humidity. Extension of greenhouses north and south, can make shed light distribution. Use of dust-free film can increase the shed light transmittance. Shed to set up a wind barrier or hang plastic film. Large air humidity in the greenhouse, easy to disease after planting seedlings. Film mulching, furrow irrigation, timely ventilation, can regulate shed humidity. Second, Shi enough fertilizer, plowing farming. Spring eggplant growth period results long, large amount of fat absorption. Prior to planting, disinfection of pigs with manure per acre 6 to 7 square meters, and mixed with 25 kg of potassium sulfate, deep plowing 20 cm or more, so that the soil to form a good water and fertilizer gas heat traits. It is best to replace the new membrane before planting. Third, nurturing strong seedlings, timely grafting. Grafting for root cultivation is a key technique for spring stubble eggplant to overcome continuous cropping obstacles and Verticillium wilt. Rootstock can choose to use either red tomato or CRP, scion can choose green or oval, green tea, timely sowing years ago, enhance strong seedlings. When the rootstock and scion are long
