I. Wheat standardized seeding technology
Standardized seeding techniques for wheat include tilling, soil preparation, ploughing, or rolling after rotavating. Suitable for lyrical and pre-planting stalks. Special attention should be paid to watering and hoeing or repression in solid soil, and dressing with seed dressing or coating agent should be appropriate. Seeding, guarantee sowing quality, suppression after sowing and so on. Applicable to Huanghuai winter wheat area and northern winter wheat area.
Second, semi-finished sowing high-yield cultivation techniques
The technology is in the wheat field with good soil fertility, fertilizer and water, and appropriate reduction of basic seedlings. Semi-finished seeding requires 130,000-180,000 basic seedlings per acre to build a reasonable population, promote individual development, and make spikelets, spikes, and grain weights. To achieve high-yield, stable production, low-cost technology system. Suitable wheat areas can determine the number of semi-finished seedlings based on local ecology and soil conditions to avoid large seedings.
Third, soil testing and fertilizer application
The technology is based on a field soil test and fertilizer field trials based on a fertilizer management technology. Mainly based on the total amount of fertilizer needed to achieve the target yield of wheat, the required fertilizer rules and fertilizer effects at different fertility stages, based on the rational application of organic fertilizer, put forward the application amount of fertilizer (mainly nitrogen, phosphorus and potassium fertilizer) and fertilization period. And application methods.
IV. Nitrogen fertilizer post-shift high-yield and high-quality cultivation techniques
The technology is a technical system that combines the proportion of winter wheat at the end of topdressing, the shift of N fertilizer in spring, and the appropriate amount of N fertilizer. It is mainly applicable to the Huanghuai winter wheat region and the northern winter wheat region in the north latitude 35-38.
V. Water-saving and high-yield cultivation techniques
This technology is used to select water-saving and drought-resistant varieties, suitable for late sowing, basic seedlings, enough planting of feet, application of phosphate fertilizers, and re-application of base fertilizers to adjust soil water storage, reduce the number of irrigations, and increase irrigation volume. High-yield cultivation techniques for water use efficiency. Applicable to Huanghuai winter wheat area and northern winter wheat area. Sixth, late sowing wheat strain high yield cultivation techniques
The technique is to increase the quality of the sowing seedlings and increase the quality of the sowing seed, supplement the sowing amount lately, supplement the fertilizers lately, increase the fertilizing material, and supplement the fertilizer by using fertilizers in the case that the sowing date of wheat is postponed. Scientifically managing and cultivating seedlings with multiple seedlings and Other techniques of "four supplements and one promotion" to achieve a high-yielding cultivation technology system for wheat.
Seven, wheat antifreeze high-yield cultivation techniques
Wheat anti-freezing high-yielding cultivation techniques are mainly strain techniques for preventing and remedying wheat freeze injury. The types of frost damage in wheat production in China mainly include freezing injury in winter, freezing injury in early spring (cold spring), and low-temperature chilling injury. The techniques for preventing freezing injury include the use of appropriate winter and spring varieties, proper sowing and improved sowing quality, and cultivation of strong seedlings. The strain-remediation techniques for remediating wheat freeze injury include watering and topdressing nitrogen fertilizer immediately after freezing.
