Embodiment 1

[0020] A method for overcoming the continuous cropping obstacle of open field watermelon, said method comprising the following steps:

[0021] The first step is sunning. After the watermelon is harvested, plow 25cm deep in summer from early July to the end of August, once every 20-30 days, twice in a row;

[0022] The second step, at the beginning of September, plant alfalfa. When the alfalfa is 15-20cm high, cut off the alfalfa and crush it to 3cm long, flatten the ground, and plow 25cm deep;

[0023] The third step is freezing. From October to January in autumn, plow 25cm deep, once every 20-30 days, 2-3 times in a row;

[0024] The fourth step, in March of the next year, use 1500kg of farmyard manure and 5kg of soil conditioner per mu to make medicinal soil, wherein medicine: soil=1:10, and sprinkle the treated soil from the first to third steps at the same time. on the soil; the farmyard manure is a crop straw fertilizer that has been retting at high temperature according...

Abstract

The invention provides a method for overcoming continuous cropping obstacles of outdoor watermelons. The method includes the following steps that upturned soil is sunned, after harvesting of watermelons, from early July to the end of August in summer, and soil is deep ploughed twice by 25 cm, once every 20-30 days; In the early September, alfalfa is planted, when alfalfa grows to 15-20 cm, alfalfais cut and crushed to the length of 3 cm, the ground surface is leveled, and soil is deep ploughed by 25 cm; upturned soil is frozen, and from October in autumn to January of the coming year, soil isdeep ploughed twice or three times by 25 cm, once every 20-30 days; in March of the next year, 1500-2000 kg of farmyard fertilizer and 5-8 kg of soil conditioner are used in per mu of soil for preparing medicinal soil, wherein the ratio of the traditional Chinese medicine to soil is 1 to 10, and meanwhile the medicinal soil is spread into treated soil; intensive soil preparation is conducted, andnext batch of watermelons are planted. The method overcomes the problem that an existing method for overcoming continuous cropping obstacles of the watermelons is low in prevention efficiency.

Description

technical field [0001] The invention belongs to the technical field of melon and vegetable cultivation, and in particular relates to a method for overcoming obstacles to continuous cropping of watermelons in the open field. Background technique [0002] In recent years, the rapid development of watermelon production has not only brought great demand for people's lives, but also brought considerable economic benefits to vegetable farmers. However, since the vegetables cultivated in the greenhouse can be produced every year regardless of the season, the ecological balance in the natural state has been changed. Excessively high soil yield rate, farmers blindly increase fertilizer input, exacerbated nutritional imbalance, various degrees of soil deterioration, physiological diseases, continuous cropping obstacles, substantial decline in yield and quality, and even barren sheds in some places. In response to this situation, agricultural science and technology personnel are con...
