If you want to grow wheat, you must master the water-saving technology in planting.
As an important food crop in China, wheat can not only solve people's food and clothing problems, but also play a great role in improving people's living standards. The north is China's main wheat producing area, but the agricultural irrigation water in the region is very lacking, and the groundwater level is also declining year by year. Under such circumstances, we must grow wheat and develop the wheat economy. We must study the water-saving technologies in planting.
I. Planting of northern wheat
In the northern part of China, wheat has a long history of planting, and the planting area is large and concentrated. Especially in the northeast region, fertile black land provides good conditions for spring wheat and winter wheat planting. The advantage of the plain region is in the development of modern agriculture. Stand out, the mechanized planting of wheat not only reduces production costs, but also increases planting yields and totals. The northern region has become a veritable wheat producing area in the country, and is in a leading position in the economic development of wheat. However, the drought in the northern region has been plaguing the cultivation and development of wheat. According to relevant information, in the spring and winter season agricultural planting in the northern region, even if 80% of the irrigation water in the region is concentrated in the wheat base, it will still not be able to meet the planting. Water demand. This lack of water not only restricts the yield of wheat, but also dampens the enthusiasm of the growers. In the exploration of how to solve this problem, in addition to the construction of water diversion works, the most effective way is to use advanced wheat planting and water-saving technology to solve the problem of water shortage on the spot.
Second, water-saving technology in wheat planting
There is an overall shortage of available water resources in the world, and the distribution of water resources in China is also less in the south and more in the north. Since ancient times, the southern region has been dominated by water-demanding crops, while the northern region has been dominated by drought-tolerant crops. However, it is often subject to water shortages. Therefore, in the process of modern agriculture, water-saving technologies It has always been an important part of modern planting technology, and its research and application are very extensive. Wheat cultivation in the northern regions often uses water-saving technologies, and has achieved certain benefits through long-term production practices. According to the current technical conditions, the technical measures that can play a role in water saving mainly include the following aspects:
(1) Planning and designing planting land
In the modern wheat planting base, planning and designing the planting land can not only effectively save water, but also facilitate later growth management. According to the water-saving technology of wheat planting land, when planning the construction of plots, the best size is about 60 square meters; the slope of the wheat field is about one-fifth to two thousandth. The wheat field thus designed has the least loss in irrigation water consumption, and is most beneficial to the absorption and utilization of wheat seedlings in terms of water flow. The normal evaporation is also much less than that of other wheat fields. In addition, when transporting irrigation water remotely, try to choose pipeline transportation, which not only can reduce the loss in the middle, but also increase the transportation efficiency, which is very beneficial to the water conservation of wheat planting.
(2) Strengthening the rationality of planting density
In the cultivation of wheat, by adjusting the planting density, not only can the wheat seedlings have the best growth space, but also can significantly reduce the unfavorable transpiration of the plants, and also reduce the inefficient evaporation of water in the wheat fields. From the regulation of water-saving experiments in the northern region, the most favorable planting density for wheat water saving in the region is 450,000 plants per mu. When the amount is above or below this, the transpiration of seedlings increases, and the average soil content in wheat fields The decrease in water volume is not conducive to the water-saving growth of wheat. Therefore, for small wheat field growers in the northern region, wheat seedling cultivation can be carried out according to this density to ensure the realization of water saving targets; for large commercial wheat planting bases, it can be determined by standard field experiments according to specific wheat field conditions and planting conditions. The density of the most suitable water-saving wheat seedlings in the base is then applied to the production, so that science can guarantee the effectiveness of the technology.
(3) R&D and promotion of water-saving wheat varieties
In the water-saving technical measures of wheat, in addition to the above-mentioned planting environment change measures and density adjustment measures, the irrigation water consumption can also be reduced through the selection of wheat varieties. In general, planting different wheat varieties in the same area presents different water needs. Therefore, in the case of relatively tight irrigation water, it is possible to consider the use of water-saving varieties with relatively low water requirements. This will not only achieve the high-quality and high-yield goal of wheat planting, but also reduce production water consumption and capital investment. From the results of water-saving studies of wheat varieties, under the same conditions of yield and quality, the water-splitting performance of the wheat-heavy heavy-duty varieties with more panicle-type varieties is better, that is, the water use of the panicle-heavy wheat varieties. The conversion rate is higher and the amount of water used for irrigation is relatively small. Therefore, in the wheat cultivation in the northern region, if the irrigation water in the wheat field is relatively tight, the wheat varieties with heavy panicles should be given priority, the seeds suitable for planting in the region should be selected, and the accurate normal irrigation water consumption should be gradually summarized according to the production practice, and Through the rotation of multiple spike heavy wheat varieties, the varieties with the best water-saving performance and the highest comprehensive benefits were screened. This not only solves the problem of shortage of production water resources, but also ensures the planting efficiency.
In short, water shortage is a global problem. China is a big agricultural country. The area of ​​cultivated land that needs irrigation water is huge, but the clean water resources that can be used are very tight. The completion of the South-to-North Water Transfer Project supplements the water available in the north to some extent. However, it is not yet fully beneficial to the field of production and planting. In the northern wheat planting, in addition to the above-mentioned water-saving technology, it is also possible to solve the shortage of production water by improving the water diversion irrigation system in the region and adopting advanced irrigation systems and covering planting. On the other hand, in the future wheat planting, we must not only further improve and develop advanced water-saving technologies and products, but also improve the wheat field water conservancy projects in the region, ensure the smooth flow of agricultural irrigation water systems, and make the modern agricultural economy as active as water currents. It will continue to promote the growth of the wheat economy and achieve the goal of high-quality, high-yield and high-quality wheat economy.
