Eight-step cultivation of water-saving and high-yielding wheat in dryland farming

First, choose the soil with deep soil, high fertility, and the output index is 400-500 kg per acre of dry-land wheat fields with water-free conditions. Rational rotation can maintain the soil nutrient balance, adjust the accumulation and consumption of various nutrients, restore and improve soil fertility. Peas, lentils, canola and other crop rotations can be used to fertilize fertility.

Second, deep plowing Deep plowing to deepen the tillage layer, increase the amount of plough layer precipitation in the rainy season in the coming year, and expand the absorption range of the root system, the depth of the till 25-30 cm is appropriate.

Third, basal wheat dryland wheat water-free conditions, seedling growth is weak, lack of roots and tillers, the main direction of attack should focus on the ground to increase the growth and increase the ear, underground promote deep root development. Therefore, the characteristics of early and deep development of fertilizers should be highlighted, and the emphasis should be placed on organic fertilizers, inorganic fertilizers, and NPK combined application. General application of organic fertilizer per acre 3000 to 5000 kg, 10 to 12 kg of pure nitrogen, phosphorus (P2O5) 6
~ 8 kg, potassium (K2O) 5 ~ 8 kg, zinc sulfate 1 kg, borax 0.5 ~ 1 kg. The fertilized material was applied to the soil in combination with a deep ploughing basal fertilizer to promote the vegetative growth and tillering of winter wheat seedlings and increase the panicle number.

Fourth, selection and selection of high-yield and high-quality drought-resistant wheat varieties. 15-30 days before sowing, dressing with Triadimefon can inhibit the occurrence of diseases such as wheat rust and powdery mildew. Use 2 grams of triadimefon per kilogram of wheat seedlings, mix thoroughly with a seed-sterilizer, and keep for 1 to 2 days.

Fifth, strong seedlings can not be used ridge, row spacing (20 ~ 22 cm) sowing. Cultivate strong seedlings, create a reasonable group structure, timely planting, require basic seedlings 120,000 to 160,000, 6 to 7 main leaf blades before winter, 700,000 to 800,000 total pre-winter months, 800,000 total springs ~ 1 million, about 500,000 spikes per acre.

6. The use of hoe and pressure for cultivating and suppressing droughts by cultivating and suppressing the soil shall require timely retrenchment of the soil after raining and returning to the soil in early spring. In particular, early spring should use a combination of maggots and pressure to squash after the first repression.

VII. In the later period of the top-dressing, if there is a phenomenon of de-fertilization, it is necessary to perform extra-root fertilizer or borrow fertilizer according to the conditions.

VIII. The suitable harvest period for harvesting wheat is the late wax ripening period. In order to reduce losses, in addition to selecting varieties that are precocious and resistant to sprouting, they should also seize the opportunity to harvest, thresh, and store in time.

Large Mesh Belt Drying Machine

The Large Mesh Belt Drying Machine equipment is mainly used for the batch continuous drying of materials, which has the advantages of fast drying speed, high evaporation intensity and good product quality. It is widely used in the drying operations of flake, strip and granule with good air permeability, such as traditional Chinese medicine, fruits and vegetables, aquatic products, native products, feed and chemical raw materials.
