High-yield arrowhead culture method

Abstract

The invention relates to a high-yield arrowhead culture method, which is applicable to mass culture in the low-lying paddy field regions of the middle and the lower reaches of the Yangtze River. The technical scheme which is adopted by the invention to solve technical problems is as follows: reasonably choosing a variety to be cultured, accelerating germination and growing shoots before field planting, reasonably compactly planting the shoots according to climate, soil and variety conditions, strengthening water and fertilizer management, conducting the works of loosening the soil, removing weeds and pressing down leaves well, strengthening the control of diseases and pests, and picking arrowheads in time. The high-yield arrowhead culture method changes the history of sporadically culturing or naturally growing arrowheads in the past, artificial control is effectively implemented in the whole culture management process, the product quality and the yield are remarkably increased, and the 750kg to 1000kg of arrowheads can be yielded per mu on average.

Description

technical field [0001] The invention relates to the technical field of aquatic vegetable cultivation, in particular to a high-yield cultivation method of sagittarius. Background technique [0002] Sagittarius, also known as swallowtail grass, belongs to the herbaceous plant of the Laxaceae family and is an aquatic vegetable. Sagittarius propagates by the terminal buds of bulbs. The corm is 3-5cm high, 3-4cm in diameter, spherical or ovoid, with 2-3 ring-shaped nodes, with brown scale leaves on the nodes, and the terminal bud at the apex is pointed. In spring, when the temperature reaches above 14°C, the top buds of the corm will germinate and produce leaves, and fibrous roots will emerge from the third node of the stem, sprouting and growing. Judging from the current situation of Sagittarius cultivation, sporadic cultivation has been the mainstay in Jiangsu and Zhejiang. For a long time, due to the lack of cultivation technology and management experience, large-scale produ...

Problems solved by technology

Judging from the current situation of Sagittarius cultivation, sporadic cultivation has been the mainstay in Jiangsu and Zhejiang. For a long time, due to the lack of cultivation technology and management experience, large-scale production has not been formed, and the following problems have arisen: First, many places have retained the same species for many years, and the cultivated species The continuous degradation leads to low yield and poor quality. Second, due to the small scale and small amount of sporadic cultivation, the domestic market for sagittarius is in short supply, resulting in a large gap in foreign exchange earnings. Shallow water and low-lying land are not fully utilized, resulting in waste of land resources
