Problems solved by technology

[0002] Among melon and fruit vegetables, pepper, green pepper, watermelon, tomato and cucumber occupy a very important position in my country's vegetable production, with an annual planting area of ​​15-30 million mu. Due to high economic benefits and tight land resources, tomato, Continuous cropping of cucumbers, watermelons, and peppers is very serious. The land cannot be restored, the soil is exhausted, the physical and chemical properties of the soil deteriorate, and a large amount of allelochemicals and autotoxic substances that affect the growth of crops remain in the soil. The micro-ecological system is destroyed. Continuous cropping of watermelons, tomatoes, The growth of peppers and cucumbers is hindered, and they are prone to disease, resulting in a large reduction in production, quality decline, and a decline in the economic benefits of fruit and vegetable farmers. At the same time, due to the sluggish growth of vegetables, they are sick, and vegetable farmers use a lot of chemical pesticides and fertilizers, causing environmental pollution and pesticides in fruits and vegetables. Residues, affecting human health

Embodiment 1

[0019] 1) In June after the harvest of tomatoes grown in greenhouses, remove tomato stumps in the field, and stack wheat straw or straw piles with a length of 5 meters, a width of 3 meters, and a height of 1 meter on the ground, and cut the straw or wheat straw into 20 cm long; Mix 5 kg of quicklime for every 1000 kg of straw in the process of haystacking;

[0020] 2) Build a dam around the greenhouse, the dam height is 20 cm, and water is poured to make the surface water in the shed 10 cm higher than the surface, and keep the water level basically unchanged. Apply 50 g / mu of ferrous sulfate to the surface, and soak the haystack in water at the same time , surrounded by a shed, sealed, and exposed to the sun for 10 days;

[0021] 3) After 10 days, uncover the greenhouse, ventilate and ventilate, drain the accumulated water in the field, turn over the haystack after 7 days, mix 2 kg of urea evenly into every 1000 kg of haystack, keep the humidity of the haystack at 50%, and ino...

Embodiment 2

[0024] 1) In May after the harvest of cucumbers cultivated in greenhouses, remove the cucumber stumps in the field, and pile up straw piles with a length of 3 meters, a width of 4 meters, and a height of 1.2 meters on the surface, and cut the straw into 25 cm long; For every 1000 kg of straw mixed with 3.5 kg of quicklime;

[0025] 2) Build a dam around the greenhouse with a dam height of 20 cm. Irrigate water so that the surface water in the shed is 10 cm higher than the surface, and often keep the water level basically unchanged. Apply 500 g / mu of ferrous sulfate to the surface and soak the haystack at the same time. In the water, the four sides are covered with a shed, sealed, and exposed to the sun for 14 days;

[0026] 3) After 14 days, uncover the greenhouse, ventilate and ventilate, drain the accumulated water in the field, turn over the haystack after 10 days, mix 5 kg of urea evenly into every 1000 kg of haystack, keep the humidity of the haystack at 40%, and inoculat...

Embodiment 3

[0029] 1) At the end of August after the harvest of watermelon cultivation in greenhouses, remove the watermelon residues in the field, and pile up straw piles with a length of 2.5 meters, a width of 3.5 meters, and a height of 1.5 meters on the surface, and cut the straw into 25 cm long; During the haystacking process, mix 5 kg of quicklime for every 1000 kg of straw;

[0030] 2) Build a dam around the greenhouse, the dam height is 20 cm, and irrigate to make the surface water in the shed 10 cm higher than the surface, and often keep the water level basically unchanged. Apply 1000 g / mu of ferrous sulfate to the surface, and soak the haystack at the same time In the water, the four sides are covered with a shed, sealed, and exposed to the sun for 12 days;

[0031] 3) After 12 days, uncover the greenhouse, ventilate and ventilate, drain the accumulated water in the field, turn over the haystack after 14 days, mix 3 kg of urea evenly into every 1000 kg of haystack, keep the humi...

Abstract

The invention relates to a method for eliminating facility cultivated vegetable continuous cropping obstacles and application of the method. The method for eliminating facility cultivated vegetable continuous cropping obstacles comprises the following steps of: after facility cultivated vegetables are harvested, filling water in a vegetable facility cultivation field at field temporary spare time in spring, summer and autumn, simultaneously adding a proper quantity of ferrous sulfate, stacking and soaking crop straws in the water, adding a small quantity of unslaked lime for fermentation, covering the field with films or sealing a greenhouse after four weeks, suffocating the greenhouse at high temperature by filling water, fermenting the crop straw for 7-14 days, uncovering the films, fully draining the water accumulated in the vegetable cultivation field in the greenhouse, inoculating edible mushrooms such as straw mushrooms and shiitake on the stacked and fermented crop straw, and harvesting the edible mushrooms after approximate 20-30 days. The method is mainly applied to the planting of melons, fruits and vegetables such as hot peppers, cucumbers and tomatoes.
