A simple method of Ginger cultivation with plastic Film mulching

Ginger mulch cultivation because of the increase in ground temperature, so ginger can be early sowing, prolong the growth period, improve yield, but also moisture, inhibit weed growth, reduce the number of cultivation, reduce costs. 1. Single film mulching can sow ginger 25~30 days earlier than CK, and increase yield by more than 20%. Spraying herbicide once after sowing and covering with plastic film can not only save the trouble of weeding, but also reduce the application times of herbicide. The film is usually removed in late June. The specific method is: after sowing, cover the ridge on both sides of the ditch with a film of 1.2 meters wide, take soil and compact the film, keep the distance between the bottom of the ditch and the film about 15 cm, and cover two rows with one film. After the bud emerges, when the seedling contacts with the plastic film, a hole is drilled to lead out the seedling. Second, double film mulching The author uses transparent and black film double film mulching to obtain ideal results. The specific method is as follows: after ginger is sown in the middle of April, it is covered with transparent plastic film immediately, and in the first ten days of May, a layer of black plastic film is covered on the transparent plastic film before ginger emerges. The main function of black film is shading, achieving the purpose of cooling, moisturizing, saving water and weeding. This method can not only reduce the shading cost by 200~300 yuan/mu, but also increase the yield by 30%~40%. It is a new high-yield cultivation technique worth popularizing at present.
