Tomato planting method capable of preventing orobanche aegyptiaca parasitism on tomatoes

Abstract

The invention discloses a tomato planting method capable of preventing orobanche aegyptiaca parasitism on tomatoes. The tomato planting method mainly comprises the following steps that (a) seedlings are raised, wherein an early-maturing variety is selected for tomato seedling raising and planting, and soil, vermiculite, composted farmyard manure, a bacillus subtilis fungicide and a streptomyces pactum fungicide are selected as a matrix during tomato seedling raising; (b) transplantation is performed; (c) fertilizers are applied, wherein urea is applied three times in a dripping mode before flowering and in an initial fruit-bearing stage, wherein the urea concentration is 10-4 mol / L to 10-5 mol / L; (d) first time of watering begins in a dripping mode before flowering and is stopped before harvesting, and a spore suspension of bacillus subtilis and streptomyces pactum is added for 4-5 times in a dripping mode; (f) tomato stems and leaves are broken turned into tomato field piece soil for the depth of 18-23 cm after harvesting from the end of July to the beginning of August, corns are planted after 18-23 days, and the corns are Zhengdan 958. Compared with the prior art, the method has the advantages of being quick, convenient and efficient, capable of effectively preventing orobanche aegyptiaca parasitism and remarkably increasing yield and the like.

Description

technical field [0001] The invention relates to a method for planting tomatoes, in particular to a method for planting tomatoes capable of preventing the parasitic tomato from Gualedang. Background technique [0002] Parasitic weeds are common weeds in agricultural production that can seriously affect crop yields. During the growth process of crops, they reduce crop production in various countries around the world. Obtaining all nutrients and water, due to its special life history, the damage to crops mainly occurs in the underground growth stage before emergence. [0003] Guaretang (Orobanche aegyptiaca) is a species of Orobanche aegyptiaca, which can only germinate under the condition of the presence of germination stimulating substances, and then parasitize on the root of the host and start to grow. Gualiedang is difficult to control, mainly due to its strong ecological adaptability. Each plant can produce a large number of seeds, and each capsule can contain 1600-3000 ...

Problems solved by technology

It takes a long time to breed anti-Redang varieties, and the variety of Guarentang develops quickly. Often, the tomato cultivars resistant to Liedang have not been successfully bred, and new physiological varieties have been derived from Liedang; The above-ground part of the melon and a part of the melon are used as stems, but the killing effect is insignificant compared with the tens of billions of melon seeds in the soil bank. At the same time, Fusarium is carcinogenic to the human body, and long-term use is harmful to human health. Harmful; it is theoretically feasible to use trapping crops to eliminate melon seeds in the soil, but no one has evaluated the elimination rate in the current year. Compared with the quantity, it is still unbalanced. Only by planting trap crops instead of planting host crops such as tomato for 5-10 consecutive years can we get good results, but this will inevitably affect the local tomato agricultural production and processing. industry devastated
