Embodiment Construction

[0019] (1) Variety selection: choose Lanzhou lily for lily, choose early and mid-maturing varieties for corn, such as Xianyu 335, etc. Broad beans are selected from local high-yield varieties, such as: Qinghai No. 13, Lincan No. 11, etc.

[0020] (2) Interplanting method: sow corn in one row, broad beans in two rows, and interplant 4 rows of lilies in one row of corn or two rows of broad beans. The width of the lily is 0.6 times the height of the corn plant, and the belt is east-west.

[0021] (3) Planting method: Lanzhou lily border planting, the width of the border is the width of lily, the row spacing of lily is 30cm, and the spacing between plants is 20cm. The distance between the two furrows is 40cm, the ditch is 10cm deep, the bottom of the ditch is covered with film to plant corn, the distance between the corn and the plants is 25cm, and broad beans are planted in rotation in the next year of the corn belt. The distance between the two rows of broad beans is 20cm, and t...

Abstract

According to shade tolerance of Lanzhou lily which is a perennial plant, wide and narrow belt alternated planting is adopted for interplanting, each wide lily belt is interplanted with a row of corns or two rows of broad beans, an interplanting period is three years, lilies are interplanted with the corns in the first year, and then the broad beans take the succession of corn belts in the next year. By the corns and the broad beans for crop rotation, a space barrier can be formed to inhibit large-area spreading of lily leaf wilt and root system diseases, and the plant infection rate is decreased by more than 60% as compared with that of single planting of the lilies; disorders of root exudate autotoxicity due to perennation of the lilies are abated, a community structure of soil microorganisms is changed, and development of pathogenic microorganisms is inhibited.

Description

technical field [0001] The invention relates to a three-year crop rotation method for interplanting Lanzhou lily and corn / broad bean, in particular to a high-yield and high-efficiency planting method suitable for crop interplanting, crop rotation and stubble inversion in semi-arid areas of my country. Background technique [0002] Lanzhou lily has nutritional, medicinal and health benefits, and is widely favored. The main planting areas are distributed in semi-arid areas such as Gansu, Ningxia, and Qinghai. In addition to domestic sales, the products are also exported to Japan, Southeast Asia and other countries. The economic benefits are very significant, and the production area is also expanding year by year. [0003] Lanzhou lily is a perennial plant that is resistant to cold and drought. It is mostly planted in cool and semi-arid mountainous areas with an altitude of 1700-2200m and a rainfall of 300-450mm. In this area, the income of Lanzhou lily for three years is betw...
