Before planting, sheath seeds are required to cut a small hole in the shell with scissors and then immersed in clean water for two weeks, during which time water is exchanged for sowing once the seed has sprouts. This is preceded by the application of base-based fertilizer and the pursuit of fattening based on the growth of the flower. The moisture requirements vary from one stage to another, with shallow water in the pre-growth period, mid-term deep water, to less water in the later stages, and water levels within 1. 5 metres. During the planting phase, attention is paid to the geological changes in the quality of water, the timely removal of weeds, the cleaning of surface algae mosses, etc., and the cultivation of three-to-five sheaths every half month, with three to four consecutive times。
I. The methodology of power
(1) the cultivation of poaching is generally based on sowing, with scissors cutting a small hole in the seed shell and immersing it in water for two weeks。
(2) care is taken to change water every day during the leaching period, so that seeds can sow when they have a long leaf。
(3) when planting, first the water is drained, then after a few days of sunbath, then the seed is buried, then the water management and field management are done。
Ii. Management techniques for the cultivation of flowers
1. Fertilizer water management
(1) at each stage of growth, the water required for the flower varies, with shallow water in the pre-growth period, mid-term deep water in the post-growth period and less water in the later period, with a water level within 1. 5 metres。
(2) the application of fertilization is essential if the flower is to grow rapidly, and before planting it is applied to the base weight, which is usually applied to 3,000 kg of organic fertilizer per acre and an appropriate amount of potassium phosphorus fertilizer。
(3) the fertilization phase requires light application during the seeding period, re-appliance during the bouquet formation period, indigence during flowering, application of 30 kg of potassium phosphorus and 10 kg of nitrogen fertilizer per acre during the fertilisation period。
(4) the curvature period increases by one to two times the base of the seedling period based on plant growth, and is generally followed up once every 20 days to increase the yield of the flowering result period。
Field management
(1) when planting, attention is paid to changes in water quality and bottoms, and if deterioration of water quality and bottoms is found to have to be addressed, otherwise it will lead to the death of the pollen, which will seriously affect production。
(2) weed removal is done during planting, and weeds are detrimental to the growth of the pollen, so they are required to be sprayed once a month. Aquatic plants, such as algae and moss, should appear on the surface of the water, should also be cleaned up immediately。
(3) when the flower grows three-to-five lobes, a conversion is carried out every half month, three to four consecutive times, until the roots are full of ponds。
