Problems solved by technology

However, a single control measure has many limitations. What’s more, it will cause negative impacts on the soil or crops. For example, the selection of disease-resistant varieties takes a long time, grafting cultivation has a certain impact on fruit quality, and chemical control is likely to cause soil damage. Environmental pollution, etc.

Embodiment 1

[0025] The preparation of the corncob meal in the soil conditioner of the present embodiment is as follows:

[0026] Dry the corncob and pulverize it to pass through a 200-mesh sieve. According to the mass ratio of corncob and sodium hydroxide to be 1:0.2, respectively weigh the sieved corncob powder and sodium hydroxide and mix well, and then add nicotinamide. Amine and 1-(3-hydroxy-n-propyl) cyclopentanol are ground and mixed. The amount of nicotinamide added is 2% of the mass of the sieved corncob powder. 1-(3-hydroxy-n-propyl) ring The amount of amyl alcohol added is 1% of the mass of the sieved corncob powder, then transferred to a tube furnace, carbonized by oxygen for 6 hours at a temperature of 650° C., and cooled to room temperature to obtain carbonized corncob powder.

Abstract

The invention relates to the technical field of agricultural planting, in particular to a method for relieving successive cropping obstacle of watermelons. The method comprises steps as follows: afterthe watermelons are harvested in the end of August, vines of the watermelons are pulled up together with roots, the watermelon land is cleared, and the land is deep ploughed for 20-25 cm; peanuts aresowed in the deep ploughed watermelon land, and peanut seeds germinate in the watermelon land and freely grow until withering; in the first two months before planting of the watermelons in the next year, the watermelon land is deep ploughed for 20-25 cm every 20 days and deep ploughed for 2-3 times; after treatment in S1-S3, the land is prepared finely and the watermelons are planted. According to the method for relieving successive cropping obstacle of the watermelons, the disease resistant capability of the watermelon plants is improved by improving the micro-ecological environment of soilof root systems of the watermelons, growth of watermelon seedlings is promoted, and the successive cropping obstacle of the watermelons is relieved.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for alleviating the obstacle of continuous cropping of watermelon. Background technique [0002] Watermelon, as one of the main fruits in my country, ranks first in the world in terms of cultivation area and total output, and is planted all over my country. Due to the short cycle, quick results and stable benefits of the watermelon industry, it has developed rapidly in the planting industry in recent years and has become a leading industry in the process of industrial poverty alleviation and structural adjustment in some regions. Long-term continuous cropping of watermelon will cause soil acidification, salinization, unbalanced nutrition, flooding of diseases and insect pests, and self-poisoning of watermelon, which will seriously affect the quality of watermelon and the sustainable development of the industry. Scholars at home and abroad have conducted a ...
