Soak the seeds of cherry tomatoes in 10% trisodium phosphate aqueous solution for 20-30 minutes, wash them with clear water immediately after taking them out, take out the chafed seeds, then soak them in warm water of 50 degrees for 8- 10 hours, and wrap them all with emery cloth after soaking. Choose early maturity and high yield varieties such as Sijihong and Shengnv.
It can grow normally at 10 ~ 32 ~ C, and 15~28~C is suitable. The temperature is as low as 3~C, which can be tolerated in a short time. Freezing injury will occur for a long time, resulting in slow growth of damaged roots. When the temperature exceeds 35 degrees Celsius, the leaves can't breathe and stop growing. Water-soluble fertilizers should be supplemented according to the different growth stages of cherry tomatoes, and balanced suspended carbon water-soluble fertilizers should be used in the early stage, which can balance growth, take root and strengthen trees, and be beneficial to fruit flowering and fruit setting. Use high-potassium suspended carbon water-soluble fertilizer in the later stage to promote the rapid expansion, coloring and sweetening of fruits!
After long-term continuous cropping, the growth of cherry tomato seedlings is futile, the growth potential is weak or the soil water and fertilizer are unbalanced, and the leaves turn yellow and fall off prematurely, which affects the synthesis of photosynthetic products. Cherry tomatoes are planted in the north. In order to improve the economic benefits of cherry tomatoes, protected cultivation is generally adopted. Before raising seedlings, we should make full preparations. 40%-50% decomposed organic fertilizer should be added to the land where vegetables have not been planted. One kilogram of calcium superphosphate can be added to each cubic meter of nutrient soil. After mixing, spread it evenly on the seedbed.
