Method of field management of tomato greenhouse

Abstract

The invention discloses a method of field management of a tomato greenhouse. The method includes the steps that first, soil preparation is performed through deep tillage; namely, the 30-40cm deep tillage is performed with a shovel half a month before planting; second, watering is performed, and when tomato plants are planted, the cultivation temperature is high in autumn and winter; third, water is controlled and fruit is retained because in tomato greenhouse cultivation, the tomato plants easily grow excessively and then suffer abnormal phenomena such as blossom dropping, fruit dropping and slow fruit growth; fourth, the greenhouse is kept warm and light is added; when the tomato plants are planted in autumn and winter or in winter, the temperature is lowest and the light is weakest all through the year, and thus the temperature and light management is critical to the success of the cultivation; when the temperature and light requirements are met reasonably, the cultivation effect can be good; fifth, the temperature is adjusted; generally, stove fire is closed or made to burn slowly on sunny days except special cold weather, and it wound be better if the temperature is not too high in the first half of the night; sixth, the light is adjusted; light is weak in winter, measures are taken to prolong the light application time for the tomato plants; seventh, fertilization is performed to fully promote normal and robust growth of the plants and make the plants yield more fruit. The method of field management of the tomato greenhouse can make the plants grow uniformly, increase the output and make the plants difficult to catch diseases. The method not only can promote the grade of goods but also is favorable for preventing diseases and making tomatoes continuously come into the market, and can avoid wasting labor and time, avoid premature senility of the tomato plants and accordingly improve economical benefits.

Description

technical field [0001] The invention relates to a tomato cultivation method, in particular to a tomato greenhouse field management method. Background technique [0002] As we all know, tomato planting has a long history. In the 1980s, the main varieties planted were Maofen 802 and Xifen No. 3. In the 1990s, L-402 was the main variety. The growth of the plants is uneven, the yield decreases, the coloring becomes poor, the deformed fruits increase, and the plants are susceptible to diseases. In terms of cultivation technology, the cultivation density is too high, which is not conducive to disease prevention. There is no habit of applying organic fertilizers in autumn and winter cultivation, which is prone to premature aging, less fruit per plant, and short fruiting period, which is not conducive to continuous marketing of products. Re-cultivation after a year is labor-intensive Time-consuming, especially during New Year's Day and Spring Festival. Due to the limited facilitie...

Problems solved by technology

In terms of cultivation technology, the cultivation density is too high, which is not conducive to disease prevention. There is no habit of applying organic fertilizers in autumn and winter cultivation, which is prone to premature aging, less fruit per plant, and short fruiting period, which is not conducive to continuous marketing of products. Re-cultivation after a year is labor-intensive Time-consuming, especially during New Year's Day and Spring Festival

Due to the limited facilities and high product efficiency, a certain regional effect has been formed, so it is often planted year after year, which causes poor growth. Even if a large amount of fertilizer is used, it will not be completely improved. The growth points shrink, and the new branches and leaves cannot be stretched normally, causing tomato Premature senility; although tomato does not have strict requirements on soil conditions, the oxygen content in the soil has a great influence on the growth of tomato root system. One-sided application of chemical fertilizers often leads to soil compaction, reduced soil permeability, and poor root growth and development. premature aging of tomato

Or some vegetable farmers apply too much fertilizer at one time in order to obtain high yield as much as possible, resulting in increased soil concentration, hindered root growth, and premature senility of tomatoes; After the stubble is vacated, older seedlings and leggy seedlings have formed. After planting, because the main root is damaged, it is difficult for the adventitious root to satisfy the crop's absorption of water and inorganic salts, often causing the plant stem to be hollow
