Moss, also known as Spirogyra, is a filamentous green algae. Rice paddy field or early rice field is prone to induce moss because of long-term accumulation of water, unclean water quality, overly fertile soil, and the application of unrefined organic fertilizer. Moss not only competes with rice for fertilizer, but also impedes the ventilation and light transmission of rice fields, lowers water temperature and mud temperature, and affects the growth and development of seedlings and rice, resulting in a reduction in yield.
Earth control
1 Drain the field and let the moss dehydrate and die; or in the cultivator, hand-pick the moss into the mud so that it will not see the sunlight and die without photosynthesis.
2 Spread a layer of grass ash on the moss, which contains alkali, which can cause the death of the moss; it can also be applied to the tea dry powder to increase the alkalinity of the rice field, so that the moss suitable for the acidic environment can not grow; but also the fresh maple leaves, bitter buckwheat The leaves and pine needles are crushed, and even the juice is applied to the field with slag, keeping the two or three centimeters of water layer and allowing the alkaline substances leached out of the leaves to kill the moss.
Chemical control
1 Copper sulfate. For every 667 square meters, 50 grams of copper sulphate is used to spray 30 kilograms of water; or 200-300 grams of copper sulphate is used. It is placed in a gauze bag and placed in the water inlet so that the copper sulphate melts as the irrigation water enters the paddy field.
2 moss net. The drug contains 10% each of triphenylacetate and copper sulfate, 30 grams per 667 square meters, and 30-35 kilograms of water sprayed.
3 rice Star. Use 80% Rice Star water dispersible granules or wettable powder 6 grams, mix and sieve 20-30 kilograms of fine earth soil, spread evenly with poisonous soil method. Apply 3-5 cm of water to the field and apply for at least 5 days after application. Rice Star can not only effectively control moss, but also control annual grasses, sedges, and broadleaf weeds.
4 hundred snails (45% triphenyl acetate WP). For every 667 square meters, use 32-35 grams per hundred snails, mix and sieve 20-30 kilograms of fine earthen. Bailu enemy can not only control moss, but also control snails, rice smut, and rice blast disease.
Butachlor. For each 667 square meters, use 60% butachlor emulsion 100 ml water 3-4 kilograms, spray in 20-30 kilograms of fine dry soil, mix well after boring for 2-3 hours and spread. In addition to effectively controlling moss, butachlor can also control weeds, weeds, sedges, and duckweed.
Food additives refer to chemically synthesized or natural substances added to food in order to improve the quality, color, aroma and taste of food, as well as for the needs of antiseptic and processing technology. Due to the rapid development of the food industry, food additives have become an important part of the modern food industry, and have become an important driving force for technological progress and technological innovation in the food industry
