Intercropping planting method of corns, tomatoes and pole beans

Abstract

The invention discloses an intercropping planting method of corn plants, tomato plants and pole bean plants and belongs to the field of crop cultivation methods. The corn plants and the tomato plants are intercropped every other ridge first, the width of the broad ridge is 80-90cm, the corn plants are planted with the row space of 40-45 cm and the plant space of 30-35cm, the width of the narrow ridge is 60-70 cm, and the tomato plants are planted with the row space of 30-35cm and the plant space of 30-35cm. The pole bean plants and the corn plants, and the pole bean plants and the tomato plants are intercropped within rows, and one pole bean plant is planted between every two corn plants and between every two tomato plants. The planting proportion of the corn plants, the tomato plants and the pole bean plants is 1:1:2. When the tomato plants grow to the height of 35-40cm, steel supports are arranged between two lines of the tomato plants of the narrow ridge and 1.0m above the ground, the supports support the tomato plants and the pole bean plants, and the supports used for supporting the pole bean plants and the costs are saved. The planting method fully takes advantage of the land and space resource, the three crops are well-proportioned and interact with one another, the leguminous plants fix nitrogen, the chemical fertilizers and the pesticides are saved, the planting cost is saved, the pressure of the nitrogenous fertilizer overuse to the environment is reduced, and the yield is increased on the limited land.

Description

technical field [0001] The invention belongs to crop cultivation in the field of agricultural technology, and in particular relates to an intercropping cultivation method of corn, tomato and bean. Background technique [0002] Corn is one of the main food crops in my country. It is an important food and feed crop with high yield. my country is the second largest country in the world in terms of corn production. Tomatoes and beans are important vegetable and fruit products, which are in great demand in daily life, and all three play an important role in our lives. [0003] The existing planting method of corn, tomato and frame beans is mainly that only one kind of crop is planted in one piece of land, which has the advantage that the variety is single and easy to manage, and the disadvantage is that the land utilization rate is very low and the economic benefit is not good. Over the years, experiments and demonstrations of intercropping of corn, beans, and spring wheat have ...

Problems solved by technology

It can be seen that although intercropping is not as good as single cropping in terms of management, it has a lot of room for development in increasing production and income and improving economic benefits.
