利用番茄老株具有再生新枝的特点,春季无霜后,把冬季温室内的番茄老株经过培养复壮,再作为春季秧苗移栽于大田。其根系发达,生长迅速,抗病力强,番茄产量比新苗栽植的对照组高10%左右。栽植方法:1、老株复壮春节过后,温室内不自然封顶的中晚熟品种的番茄老株上的果实快摘完时,拔除有病害和个别矮小株,留有再生能力的粗壮老株。将其下部已枯黄的叶片摘除,老株都向北倾斜45度角,再给于大水肥和全日光照,促生出与老株有45度夹角的新枝杈,便于水平移栽。每株留3～5条蘖生的新枝,其余的
The use of tomato old strains have the characteristics of regenerating new branches, no frost in spring, the old greenhouse in the greenhouse after the old strain of rejuvenation, and then as a spring seedling transplanted in the field. The developed root system, rapid growth, strong resistance to disease, tomato production than the new seedling control group about 10% higher. Planting methods: 1, rejuvenation of the old Spring Festival after the Spring Festival, the greenhouse is not naturally capped middle-late-maturing varieties of tomatoes on the old fast pick the end, remove the disease and individual short stature, leaving regenerative stout older strains. The lower part of the leaf has been removed yellow, the old strains are inclined to the north 45-degree angle, and then give a large water and fertilizer and full-day light, and the old plant to promote the emergence of a new angle of 45 degrees twigs for easy horizontal transplanting. Each plant leaving 3 to 5 new branches of the tiller, the rest
