It is suitable for rice, wheat, and wheat fields in the middle and lower reaches of the Yangtze River in the winter wheat region and in the southwestern winter wheat region, including rice, wheat, and wheat fields in Jiangsu, Anhui, Henan, Hubei, Sichuan, and Chongqing.
Semi-finished sowing high-yielding cultivation techniques
The technology is in the wheat field with good soil fertility, fertilizer and water, appropriate reduction of basic seedlings, semi-finished seeding requires 130,000 to 180,000 basic seedlings per mu, so as to build a reasonable population, promote individual development, make ear, spike, grain weight 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. The technology is applicable to the main producing wheat areas in the middle and lower reaches of the Yangtze River, the winter wheat region of Huanghuai, and the winter wheat region in the north, including most of Shandong, Hebei, Henan, Jiangsu, Anhui and Hubei provinces and Shanxi, Shaanxi, and Xinjiang. High yield wheat field.
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. Applicable to all wheat areas in the country.
High-yield and High-quality Cultivation Techniques of Nitrogen Fertilizer
The technology is a technical system that combines the proportion of winter wheat at the end of the topdressing process, the time of the spring nitrogen topdressing stage and the appropriate amount of nitrogen application. It is mainly applicable to winter wheat fields in Huanghuai area and northern North China with latitude 35 degrees to 38 degrees north latitude, including strong gluten and medium-strength wheat fields with better irrigated conditions and fertility in the middle and northern parts of Henan, Shandong, Hebei, Shanxi, Shaanxi, and Xinjiang.
Water-saving and high-yielding 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. It is applicable to winter wheat fields in Huanghuai and northern winter wheat areas, including wheat fields in north-central Henan, most of Shandong and Hebei, and relatively scarce water resources such as Shanxi, Shaanxi and Ningxia, Inner Mongolia Hetao irrigation areas.
High-yielding cultivation techniques of dry buckwheat
This technology is based on proper sowing and cultivating pre-winter seedlings, requires semi-precision sowing, will use 50%-60% of nitrogen fertilizer as the base fertilizer, and 40%-50% of nitrogen fertilizer will move to the jointing period. Top-down technical system. Applicable to latitudes of 30 degrees to 35 degrees north latitude, including Jiangsu, Anhui, Hubei, Sichuan, Chongqing and Henan in addition to rice, buckwheat, wheat and other drought and wheat.
Non-tillage, no-till and rice straw-covered cultivation techniques for rice and buckwheat
Less no-tillage cultivation techniques for rice and buckwheat mainly include seeding methods such as seedling-free seeding, seedling sowing and paddy sowing, as well as supporting techniques such as trenching, straw covering, chemical control and nitrogen fertilizer transfer. Applicable to latitudes of 30 degrees to 35 degrees north latitude, including Jiangsu, Anhui, Henan, Hubei, Sichuan, Chongqing and Shandong. The rice straw mulching and straw mulching cultivation technology is based on the no-tillage and close-grained planting techniques. Mechanical exposition and straw mulching are the core contents, and the four aspects of yield increase, efficiency improvement, fertility improvement and environment improvement are harmoniously developed. . When rice is harvested, rice stubble is left shallow, irrigation is performed by trenching, and chemical weeding is conducted 7 to 10 days before sowing, sowing with 2BJ-2 simple human planter, with 150,000 to 200,000 basic seedlings per acre and covering 200 to 300 kg of rice straw. Applicable to the southwestern winter wheat area, including Sichuan, Chongqing and western Hubei, northern Hebei, northern Hebei, southern Shaanxi and other places.
Dryland wheat mulching and straw mulching
The dryland wheat mulching technology mainly covers the land cover film, saves water and saves water, and raises the ground temperature, so that the dryland wheat can obtain high yield and stable yield, and it can be divided into two types for the cultivation of film-mulching ridge and furrow sowing and film-mulching. Straw mulching technology is a cultivation technique that covers crops and returns them to the surface to protect water, fertility and fertility. It is applicable to the northwestern region of Huanghuai winter wheat region and northern winter wheat region, including dry wheat fields in Weibei of Shaanxi Province, dryland wheat fields in Yan'an region, and dry-land wheat fields without watering conditions in Shanxi Jinnan, Jindongnan, Jinxi drought, Gansu and other provinces. . Hebei, Shandong, and Henan can also be used for reference.
Late-seeding wheat strain high-yielding 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. Scientific management, and the promotion of seedlings, etc., are all four techniques to promote technology, so as to achieve a high-yielding cultivation technology system for wheat. Applicable to late winter wheat fields in various winter wheat regions.
Wheat antifreeze high-yielding 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 in time and topdressing nitrogen fertilizers after freezing. Suitable for all winter wheat areas.
