The end of October and early November are the prime time for wheat planting. In 2011, Renshou County of Xiaochun County enjoyed a bumper harvest, of which the highest wheat output reached 370.6 kg. How to lay the foundation for the 2012 wheat harvest? Sowing is absolutely critical. Then, how can the majority of farmers' friends master the most advanced and practical sowing techniques? This reporter interviewed Renshou County's relevant agricultural experts.
The best sowing date for wheat is November 1-5. After the sowing of plots is selected, preliminary preparations should begin in early October. Firstly, the two crops need to be drained and drained. If the humidity is too high in the field, it will seriously affect the normal sowing, emergence and growth of wheat. The impact of wet damage on the yield of wheat is huge, and farmers' friends must pay great attention to it. There is also stress on dehumidification, and it is necessary to determine the location of the three trenches in each field. Requirements: To open 8 to 10 inches deep from the side of the field at a distance of 1 meter, to open a 6 to 7 inch depth of the car's groove at a depth of about 4 meters, and 10 to 12 inches deep through the heart; the bottom groove should be flat and the groove should be connected. , eliminate waterlogging.
Weeding: One-day application of the first-hand (isoammonium salt containing glufosinate), a fire, grams of trace, oxaphosphoryl and other herbicides to control a variety of grass damage.
Sowing: Aphid seeding, dense planting of sparse plants, and precision seeding: In accordance with the seeding specifications of 9-inch large-scale, 5-inch small-sized, and 3-inch-exit, axillary nests are planted in advance. Mechanical sowing can be used on the surface of the flats in the two quarters. The preliminary preparation work includes draining the surface of the car and filling the surface of the car, removing the high-altitude valley piles and residual film, cooling the soil surface, and adjusting the sowing specifications. Good machinery.
Fertilization: Use one of the following three fertilization methods: (1) Base fertilizer: Apply 70 kg of compound fertilizer or 40 kg of ammonium bicarbonate and 40 kg of phosphate fertilizer in two seasons; (2) Top dressing: three times of application, that is, 3 kg of urea per mu when 2.5-3 leaves are used for tillering, and 4 kg of mu is used for jointing fertilizer in mid-January. The combination of ear and grain fertilizers in the early stage of wheat earing and combining will be used to prevent and control scab. Potassium dihydrogen phosphate 0.5 kg plus urea (appropriate use according to the growth of wheat) Spraying 50 kg of water for foliar application can increase grain weight and seed setting rate.
Straw cover: Covering the straw after wheat sowing has the advantages of fertilizing the soil, heat and moisturizing, controlling weeds, and increasing the rate of emergence. After sowing wheat, the straw is cut into 5-6 inch long covering wheat fields. The cooked straw can be cut.
Scientific and timely application of prevention and treatment: Triadimefon or Rickett rust prevention and treatment of stripe rust, powdery mildew, carbendazim or zeocin to prevent scab, dimethoate control aphids, krypton to control red spider.
