The semi-finished sowing high-yielding cultivation technology is in the wheat field with good soil fertility, fertilizer and water, appropriate reduction of basic seedlings (13 to 200,000), promotes individual development, makes spikes, spikes, and grain weights, and achieves high yield, stable yield, and low yield. Consumption technology system.
Winter Wheat Winter Wheat Watering in Huanghuai Sea This technique is to irrigate wheat before it enters the wintering period to increase the soil moisture content, collapse the soil in the plough layer, promote root growth, and increase the ability of wheat to resist drought and cold. It is an important measure to cultivate strong seedlings. The time for winter irrigation in a region should be controlled at a daily average temperature of 3°C to 5°C, and the soil in the wheat field should end at night when it freezes and disappears. The water per mu is about 40 cubic meters. After irrigating, it is suitable to loosen the soil and close the cracks in the soil.
Water-saving and high-yield cultivation Through the application of water-saving and drought-resistant varieties, proper late planting, and the addition of basic seedlings, the high-yielding cultivation techniques of adjusting soil water storage, reducing the number of irrigations and irrigation volume, and improving the water use efficiency by using the bottom drowning water.
High-yielding cultivation of dry buckwheat is based on proper sowing and cultivating pre-winter seedlings, which requires semi-precision sowing, using 50% to 60% of nitrogen fertilizer as the base fertilizer, and 40% to 50% of nitrogen fertilizer to move up to The technical system of topdressing during jointing.
Less no-tillage rice buckwheat mainly includes seeding methods such as less-tillage tillage, sowing and sowing, paddy-field sowing and sowing, as well as supporting techniques such as trenching, straw covering, chemical removal and control.
The film coverage of dryland wheat is mainly through the surface cover film, save water and improve the ground temperature, so that the dryland wheat can obtain high yield and stable yield, and it can be divided into two types: the inter-membrane cultivation of the mulching film and the whole film covering the soil.
Straw mulching is a cultivation technique that covers crops and returns them to the surface to protect water, fertility, and fertility. It is applicable to the northwest region of Huanghuai winter wheat area and north winter wheat area, including dryland wheat fields in Shaanxi and Shanxi provinces.
In the case of late-seeding wheat strain high-yield cultivation under the condition that the sowing date of wheat is postponed, the quality of the sowing seedlings should be improved by adopting improved varieties and supplementing the seeds at night so as to make up for the night, increase the sowing amount appropriately, supplement it lately, increase fertilizer application, and use fertilizer. To supplement the night, scientifically manage and strengthen the “four supplements and one promote†technology, such as seedlings, etc., to achieve a high-yielding cultivation technology system for wheat.
Antifreeze high-yield cultivation is mainly a strain technique for preventing and remedying wheat freeze injury. The types of freezing injury mainly include winter freezing injury, early spring freezing injury 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 technology for remediating wheat freeze injury is timely watered after being frozen.
POCT system is a diagnostic system that using fluorescence immunoassay to quantify analysts
with high sensitivity by measuring laser-induced epifluorescence of test cartridges. It can be
used to screen lifestyle-related diseases from cardiac diseases, cancers, diabetes, infectious
diseases and hormonal disorder.
