1.变温处理种子法将要发芽的种子低温条件下(2—5℃)放置12—18小时,再转移至高温条件下(18—24℃)放置6—12小时,连续处理7—10天,能促进种子内部可溶性物质的转化,提高秧苗的抗寒力,加速其生长发育速度。 2.刺激法幼苗长出一片真叶后,每天定时用布轻拂幼苗3—5次,坚持10—15天,能使秧苗花蕾数、果实数、单果重都有不同程度增加,一般可增产10%以上。 3.化控法番茄始花期喷施300PPm的矮壮素,可使茎变粗,节间缩短,也能促进地下部生长,增加叶片内叶绿素含量,增加光合效率。据试验可增产13.3%。
1. Variable temperature seed method to be germinated seeds at low temperature (2-5 ℃) for 12-18 hours, and then transferred to high temperature conditions (18-24 ℃) for 6-12 hours, continuous treatment of 7-10 days, Can promote the transformation of soluble material within the seed to improve the cold hardiness of seedlings and accelerate their growth and development. 2. Stimulation seedlings grow a true leaf, the daily time with cloth breeze 3-5 times a day, insisted 10-15 days, make the bud seedling number, the number of fruits, fruit weight has increased in varying degrees, the general increase 10% or more. 3. Chemical control method The beginning of flowering tomato spraying 300ppm of CCC can make the stem thicker, internodes shortened, but also to promote the growth of the underground, increase leaf chlorophyll content, increase photosynthetic efficiency. According to the test can increase 13.3%.
