The role and application methods of wheat straw and wheat chaff mulching
Wheat straw and wheat chaff mulching is the even scattering of wheat straw or wheat chaff around autumn crops or between rows to form a certain mulch layer, with an appropriate amount of soil pressed over it in spots so as to cover and preserve soil moisture. For wheat straw and wheat chaff mulching, it is necessary to properly grasp the principles of timing, mulching amount, and rational application of chemical fertilizers, etc. 1. Timing. The relatively suitable mulching time is from late June to early and mid-July. Too early makes it easy to press down the seedlings, while too late means the crop plants are tall and not easy to work with. After mulching, if there is no rain or the rainfall is insufficient, it will affect the rotting and decomposition of the straw, and the effect will be poor, so timely watering is needed. It is also possible to water at the first topdressing at the end of June.

Key Technical Points for No-Till Planting with Rice Straw Return
No-till technology with rice straw return refers to a simple planting method in which, after the rice harvest, the rice straw is spread evenly over the field, no plowing is done, and only chemical weed control is carried out before wheat can be sown. This technology was successfully developed in May 2000 through dedicated experimental research by the Chengdu Second Institute of Agricultural Sciences. The no-till wheat planting technology with rice straw return fully combines the advantages of straw return, no-till, and broadcasting, and scientifically assembles them into a complete new technology package, which has not yet been formally reported at home or abroad. Experimental research shows that this comprehensive supporting technology not only increases

Correct Methods and Technical Key Points for Returning Wheat Straw Compost to the Field
Choose a flat spot at the edge or corner of a field close to a water source, and firm the ground. Chop the wheat straw short, soak it with water, and then build the pile. First spread a layer of wheat straw about 25 cm thick, press it firm, then pour on human and livestock manure and urine, or for every 100 kg of dry wheat straw add 0.5 kg of urea and 2 kg of superphosphate, and spread a layer of pond mud 10 cm thick on top. Then spread another layer of straw, pour on fertilizer, and cover with pond mud. Build up layer by layer in this way until the pile reaches 1.5-2 m high. Finally seal the pile with thin mud. After 30 days, turn the pile and add an appropriate amount of water. After 2 months in summer, or 3-4 months in winter, it will be

Detailed Explanation of the Technical Key Points for Returning the Full Amount of Wheat Straw to the Field
Crop straw is an important by-product of crops. It is also an important production resource for agriculture and industrial production. Returning crop straw to the field not only avoids the environmental pollution problems caused by rotting and burning, and achieves feeding the land with the land itself, but also consolidates the foundation of soil fertility for greatly increasing soil organic matter content, improving soil structure, building up soil fertility, strengthening the quality construction of cultivated land, and raising crop yield and quality. In every agriculturally developed country in the world, great attention is paid to the scientific rationality of the fertilization structure and the

Strawflower, wax flower, and everlasting flower all refer to the same flower
Scientific name: Helichrysum bracteatum. Type: perennial herbaceous flower, often grown as a 1-2 year plant. Family and genus: Asteraceae, Helichrysum genus. Aliases: wax flower, everlasting flower. Introduction: The strawflower is an annual herbaceous perennial flower; because its flowers do not wither after drying and look as if made of wax, it is an excellent material for making dried flowers, a unique natural "handicraft" of the natural world. Species in the same genus include Helichrysum arenarium, Helichrysum umbellatum, and others. Many

Detailed Explanation of the Processing Flow for Frozen Raw Peeled Shrimp
Production Method 1. Raw material selection: The requirements for raw shrimp are fresh quality, with no spoilage and no off-odor in the shrimp body. 2. Thawing: When using frozen shrimp as the raw material to process peeled shrimp, thawing must be done first. Place the frozen shrimp in a thawing bamboo basket and rinse with water. The water volume should be large to speed up thawing. Once the shrimp bodies separate from the frozen block, stop thawing. The amount thawed should be determined according to the peeling capacity, so that there is neither a gap in production nor excessive backlog, to prevent spoilage. 3. Peeling: Hold the shrimp body in the left hand with the tail and belly facing up, gently remove the shrimp head with the right hand, and carefully peel off the shrimp
