Description
Technical Field
The invention relates to planting of crops, in particular to a method for planting cherry tomatoes.
Background
The cherry tomato is a dual-purpose food of fruits and vegetables, has small fruit shape, is similar to cherry, has rich pulp, fresh and sweet taste, unique flavor and rich nutrition, also has the effects of promoting the production of body fluid to quench thirst, clearing away heat and toxic materials, invigorating stomach and promoting digestion and the like, and becomes a novel fruit in countries and regions such as European and American countries, Japan, Hongkong platform and the like in recent years.
The cherry tomatoes are annual herbaceous plants, are suitable for being planted in soil with strong illumination and deep soil layers, and are preferably cultivated in soil with rich organic matters, deep ploughing layers, good structure, looseness and ventilation. According to the traditional cherry tomato greenhouse cultivation technology, due to the fact that various pathogenic bacteria are continuously accumulated in soil in the planting process in successive years, continuous cropping obstacles occur, the yield is seriously affected, the quality is also reduced, and if pesticides are adopted for killing insects, the problem of pesticide residues still exists. In addition, the existing cherry tomato planting technology not only increases the production cost due to long-term single and excessive application of the chemical fertilizer, but also causes soil acidification and salinization, reduction of organic matter content, soil fertility and trace element attenuation, soil erosion and hardening, and seriously affects the growth, yield and quality of crops. Excessive fertilization or too dense fertilization time affects the yield and quality of cherry tomatoes.
The invention patent with publication number CN108235932A discloses a cultivation method capable of obtaining green organic cherry tomatoes, which adopts decomposed organic substrates to provide sufficient nutrients for the cherry tomatoes, and adopts red-blue mixed light irradiation to promote the growth of the cherry tomatoes and increase the sweetness of the cherry tomatoes; the problem of pesticide residue is solved by regularly spraying the traditional Chinese medicine decoction to prevent and control plant diseases and insect pests, so that the green organic cherry tomatoes are obtained. However, this method requires irradiation with red-blue mixed light every day, and requires a time of 8 hours or more, which is expensive. The invention patent of publication No. CN108739128A discloses a cherry tomato planting method, which solves the problems of poor quality and low yield of cherry tomatoes caused by fruit type deformity existing in current planting by specifically limiting each step from seed selection to pruning, and analyzes the influence of various varieties on cherry tomato malformation rate, cherry tomato soluble sugar, soluble protein and total yield when the varieties are sowed at different periods, but does not limit the way of applying fertilizer before planting and controlling pests during plant growth.
