Method for delayed cultivation of tomatoes in autumn

Abstract

The invention discloses a method for delayed cultivation of tomatoes in autumn, which consists of the following steps of 1, selection of varieties: early-maturing big-fruit type varieties are mainly adopted; 2, seeding in optimum period and erecting a sunshelter: early maturing varieties are seeded on 15th to 23rd in July, medium and late maturing varieties are seeded in the first ten days and the middle ten days in July, and the seedling age is 25-30 days; 3, ploughing under to great depth at an early date: after the preceding crops are harvested, dead twigs and withered leaves and weeds are cleared away in time, stubbles are deeply tedded and soil is cured so as to make preparation for bed adjusting; 4, early planting in optimum period: early planting is needed to be carried out in the last ten days of August when a young seedling has seven main leaves and slightly squares, and if the young seedling is planted late, the young seedling possibly excessively grows in the seedling bed, matures late and is easily damaged in later period; and 5, early coverage for winter protection: the step is carried out before and after Cold Dew, the weather turns cool and when the outside temperature drops to below 20 DEG C. The method has the advantages that the plants grow in order, the yield is increased, and the plants are not easily infected with diseases, the grade of commodities is improved, disease prevention and continuous appearing on the market of products are favored, labor wasting and time wasting and premature senility of the tomatoes are avoided, and accordingly the economic benefit is improved.

Description

technical field [0001] The invention relates to a tomato cultivation method, in particular to a tomato cultivation method in autumn. 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 facilities and ...

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
