A high-yield planting method for interplanting soybean with spinach for seed production

Abstract

The invention discloses a soybean-interplanting high-yield planting method for seed production spinach. The method includes the steps that spinach varieties which are resistant to disease, high in yield and stress resistance and good in commodity and soybean varieties which are wide in adaption, resistant to lodging and moderate in duration period are selected; in late February to beginning of March, base fertilizer applying is carried out in cooperation with spring ploughing and soil harrowing, leveling and preparation, and soil harrowing, leveling and preparation are carried out in time after fertilizer applying; seed dressing is carried out with nitragin before soybeans are seeded, and seeding can be carried out when seeds are dried in the shade; timing seeding is carried out, spinach is planted in an even-row mode, the row spacing is 50 cm to 60 cm, a row of soybeans are interplanted in rows, and the soybeans are 25 cm to 30 cm away from the spinach; or spinach is subjected to wide-narrow row planting, the narrow row spacing is 30 cm, the wide row spacing is 60 cm to 70 cm, two rows of soybeans are interplanted in wide rows, the soybean row spacing is 30 cm, and the soybeans are 20 cm away from the spinach; the soybean plant (hill) spacing is 13 cm; reasonable field management is carried out till harvesting is carried out. According to the high-yield planting method, coordinating yield increasing function of soybean-interplanting seed production spinach is fully developed.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a high-yield planting method for interplanting soybeans with spinach for seed production. Background technique [0002] Ningxia irrigation area is rich in light and heat resources, fertile soil, convenient drainage and irrigation, long frost-free period, good coordination of agricultural and natural resources, and superior natural conditions provide favorable conditions for spinach seed production. [0003] Spinach belongs to Chenopodiaceae and is a vegetable with strong cold resistance among green leafy vegetables. It can be cultivated in all seasons in Ningxia, with a short growth period and early harvest. Spinach is generally dioecious, and there are also monoecious persons. The female plant has larger leaf clusters, well-developed leaves, and bolts later than the male plant; the male flower has no corolla, has a lot of pollen, and is pollinated by wind.

Problems solved by technology

However, at present, there are generally irregular planting specifications in the interplanting soybean production of seed production, spinach, large planting volume, small plant spacing, high density, and easy lodging in the late growth stage; thus, in the interplanting technology of seed production and spinach, the coordinated production increase function of soybean has not been achieved. can fully and effectively play
