一、番茄落花问题的存在番茄是一种喜温暖的蔬菜植物,不耐寒冷但也不耐炎热,温度过高或过低,不但影响植株的生长与发育,而且会引起落花,尤其夜间的温度,如果高于22—25℃,或低于12—15℃,就会落花而不能结实。由于这个缘故,番茄在长江下游栽培时,一年可以播种两次。一次在早春播种(如用温床育苗者可提早到冬季播种),清明前后定植,5—7月采收。又一次在

First, the existence of tomato drop flowers The tomato is a hi warm vegetable plants, intolerant of cold but also intolerant of heat, the temperature is too high or too low, not only affect plant growth and development, but also cause falling, especially at night temperature If it is higher than 22-25 ° C, or lower than 12-15 ° C, it will fall and can not be strong. For this reason, tomatoes can be planted twice a year when planted in the lower reaches of the Yangtze. Once sown in early spring (such as breeding seedlings with hotbed can be sown early in winter), before and after planting clear harvest, May-July harvest. Again
