Coincided with the rice field moss
Moss, also known as Spirogyra, is a filamentous green algae. Rice paddies or early rice fields are prone to induce moss in the long-term accumulation of water, unclean water quality, soil is too fertile, and the application of unripe organic fertilizer is more. Moss not only competes with rice for fertilizer, but also obstructs ventilation and light transmission in paddy fields, lowers water temperature and mud temperature, and affects the growth and development of rice seedlings and rice, resulting in reduced yields.
Prevention of moss usually adopts the following methods: First, drainage and drying fields, let the moss dehydrated and died. It is also possible to put moss into the mud by hand during cultivating so that it will not get sunlight and the moss will not be able to carry out photosynthesis and die. The second is to sprinkle a layer of plant ash on the moss. Because the plant ash contains alkali, it can cause the death of moss. The use of tea dried powder can also be used to increase the alkalinity of rice fields, so that moss suitable for acidic environments cannot grow. Fresh maple leaves, buckwheat leaves, and pine needles can also be crushed, and even juice with slag can be applied to the field, keeping 2-3 cm of water in layers, allowing alkaline substances leached by the leaves to kill the moss.
Chemicals can also be used to control, the effect is better. The pesticides suitable for controlling moss in rice fields include:
First, copper sulfate. With 50 grams of copper sulfate, add 30 kg of water spray. Or 200-300 grams of copper sulfate, into a gauze bag, placed in the inlet, so that the copper sulfate melted into the paddy fields with irrigation water to kill the moss.
Second, moss net. The drug contains 10% each of triphenylacetate and copper sulfate, 30 grams per 667 square meters, and 30-35 kilograms of water added.
Third, rice Star. Use 80% Ricestar water dispersible granules or 6g of wettable powder, mix 20-30kg of sifting fine soil and spread evenly. 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.
Fourth, Bailu enemy (45% triphenyl acetate wettable powder). For every 667 square meters, use 32-35 grams per hundred snails and mix evenly with 20-30 kg of sifted fine soil. Bailu enemy can not only control moss, but also control snails, rice smut, rice blast disease.
Five, butachlor. For every 667 square meters, use 60% butachlor emulsion 100 ml water 3-4 kg, spray in 20-30 kg of fine dry soil, mix and boring after 2-3 hours spread. Butachlor can effectively control the moss, but also can control weeds, prickly ash, Alias ​​sedges, duckweed and other rice field weeds.
