Tomato tree type cultivation method preventing root system from decaying and preventing leaves from yellowing

Abstract

The invention discloses a method for cultivating tomato plants which prevents the root systems from decaying and the leaves from etiolating. The method solves the problem of decayed root systems mainly by pruning the roots during the seeding stage, promoting water roots, cleaning the root systems on a regular basis during the growth, raising the concentration of dissolved oxygen in nutrient fluid and increasing the times of nutrient-fluid circulation during the late stage of growth, etc. In the fruit-bearing stage, phosphate and potash fertilizer, and iron and zinc fertilizer are sprayed to the canopy of the tomato plants to solve the problems that the root systems cannot absorb enough nutrients and that not enough nutrients are transformed into leaves. Therefore, the nutrient balance during the period of cultivation and growth is adjusted, thereby solving the problem that new leaves are likely to etiolate, shrink, or even decay during the fruit-bearing stage. By adopting the method to cultivate tomato plants, the problems of root system decay and leaf etiolation during the fruit-bearing stage can be solved, the annual growth of tomatoes can be ensured, and the annual yield of tomatoes can reach more than 10,000. Tomato plants cultivated by the method are suitable for industrial production and for sightseeing.

Description

technical field [0001] The invention belongs to a vegetable cultivation method, in particular to a tomato tree cultivation method for preventing root rot and leaf yellowing. Background technique [0002] The conventional cultivation method of tomato is mainly soil cultivation or greenhouse soilless cultivation. Generally, spring stubble or autumn stubble is used for segmented cultivation, and each plant usually produces 10 to 16 tomatoes; due to the high temperature in summer and low temperature in winter, long-season cultivation with annual growth is rarely used; and due to the difficulty of management, fast-growing, There are fewer hydroponic cultivation methods with high yield and good quality. [0003] Tomato tree cultivation mainly adopts the method of soilless cultivation. The vegetative growth period grows, and a strong canopy like a tree crown is formed before fruiting. After entering the fruiting period, each tomato plant can bear 2000-4000 fruits at a time, and c...

AI Technical Summary

Problems solved by technology

[0004] However, there are two problems in the tomato tree cultivation, one is that the root system is rotten, which causes the aboveground leaves to wilt; the other is the yellowing and shrinking of new leaves during the fruiting period

These two problems have seriously affected the normal growth of tomatoes, resulting in the failure to achieve the expected number of results and canopy area of ​​tree cultivation, affecting the ornamental effect
