Problems solved by technology

The reason is that the cultivation and management of marigolds are not carried out according to the ecological habits of marigolds in production, which leads to more serious marigold diseases, and the per unit yield and benefit decline year by year

specific Embodiment approach

[0011] The technology of the present invention belongs to the national "Tenth Five-Year Plan" scientific and technological research project (2001BA508B05) and the "Tenth Five-Year Plan" major scientific and technological research project of Heilongjiang Province (GB01B301-05). In 2005 and 2006, Heilongjiang Xiangfang Farm Experimental Station and Yanjiagang Farm Experimental Station carried out three-dimensional intercropping experiments and demonstrations of onions and marigolds. Its specific implementation is as follows:

[0012] Soil selection, soil preparation, fertilization, and ridging

[0013] It is better to choose neutral soil with irrigation conditions, fertile land, flat soil and good permeability. It is best not to choose onion and garlic stubble, and do not choose plots that have used long-lasting herbicides such as Pushite, Atrazine, Douhuanglong, and Luhuanglong in the previous year. 30cm deep pine in autumn, 15cm rotary tillage, ridges after leveling and harr...

Abstract

The invention is concerned with the establishment of high efficiency solid interdrop planting mode based on the coordination of the ecology of the onion and marigold according to the different ecology habits of them. The invention can reduces the happening of plant diseases and insect pests and the drug using times, extend the growing period, improve the land use rate, and achieve the high yield by giving enough light irradiation, humidity and ventilation. The per unit area yield of the intercropped onion is 1650kg / 667m2 that the benefit is 799RMB / 667m2, the marigold is 1350kg / 667m2 that the benefit is 607RMB / 667m2; the whole benefit is 1406RMB / 667m2, which the efficiency improves 46.81% and 31.34% respectively.

Description

technical field [0001] The invention belongs to the technical field of agricultural production. It is a high-efficiency three-dimensional intercropping planting model based on the different ecological characteristics of onion and marigold, and based on the ecological coordination and interaction of the two crops. Background technique [0002] With the continuous optimization and adjustment of Heilongjiang's agricultural industry structure and the in-depth implementation of the green brand strategy, the vegetable and flower industries have achieved considerable development. Mass production practice has proved that marigold and onion are high-efficiency economic crops, and their planting benefits are 3-5 times that of grain fields. They have become new highlights for the optimization and adjustment of agricultural structure and the increase of farmers' income. [0003] According to statistics, since 1990, the Northeast Institute of Geography and Agroecology of the Chinese Aca...
