In the paddy field, the cotton swab flocks are pressed around the seedlings to make the seedlings delayed, and the dead seedlings or the single plants have no tillers; the water temperature is lowered, and when the water sponge covers an area of ​​30%, the water temperature can be reduced by 2-3°C; when the water When cotton occurs in large quantities in paddy fields, the applied fertilizer cannot fall into the roots of rice, and competes with rice to compete for water and compete for growth. Severe paddy fields occur in the spongia, the plant height of the rice is reduced, the leaves are yellow, and the yield is reduced by about 30%. I. Sponge characteristics The Spirogyra is a 1 year old aquatic algae plant of the family Starophyceae. It reproduces or reproduces by filamentous breakage. The spores germinate into new individuals and spread with water. Sponge is very strong in vitality and fecundity, and is good for fertilizer, especially in the condition of large application amount of phosphate fertilizer, and its growth speed is accelerated. Saline-alkali hydroponic growth with soil pH of about 7.5 is most suitable. Generally, after spring irrigation in the paddy field, it begins to occur in mid-May. In early June, it will rapidly multiply and harm as the temperature rises and the effect of phosphorus and organic fertilizers in the field is exerted. Second, the law of occurrence Drought, lack of water, lack of water resources, and irrigation often use recycled water or unfilled fields are prone to damage by spirolacrine, and the spongiform spores and filaments in irrigation drainage channels will flow into the paddy fields. A large number of spongy populations remained in the fields with high spongiosis in the previous year, and a large number of recurrences occurred after irrigation in the following year. Deterioration of water quality, high-level application of phosphate fertilizer, the formation of fertilizer can promote water sponge. The major causes of spongiosis include: (1) Paddy rice fields with long-term accumulation of low-lying rice fields, poor drainage, and deterioration of water quality. (2) Large-scale application of phosphorus-containing fertilizers to form fertilizer-water rice fields. (3) The paddy fields where high water sponges occurred last year. Third, control methods (1) Scientific fertilization, reasonable formula of nitrogen, phosphorus and potassium. (2) Rational irrigation and drainage, using shallow, dry, wet irrigation methods. (3) Artificial salvage, when the spirogyra forms a small amount of flakes in the field, it is first manually removed, and although the remaining spirochete filaments have been broken, their absorption capacity is extremely strong, and they breed quickly and form a new group, but the broken filaments The wound contact with liquid medicine will cause the spirochete to poison and die quickly. (4) Chemical control: 26% water-based wettable powder of 65 grams per acre. After 15 days of rice transplanting, water sponges are applied in the “mass phaseâ€; after July, they are in “spread†stage per acre. Dosage of 100 grams, mixed with fertilizer or mixed with fine soil, cut dry soil can not be used, after the field to maintain the water layer 4-6 cm 5-7 days. Weak seedlings or waterlogged fields are disabled for the use of water sponges. Probiotics are a class of active microorganisms that are beneficial to the host by colonizing the human body and changing the composition of the flora in a certain part of the host. By regulating the immune function of the host mucosa and system or by regulating the balance of intestinal flora, promoting nutrient absorption and maintaining intestinal health, resulting in the production of single microorganisms or mixed microorganisms with well-defined composition that are beneficial to health.
