Description
Technical Field
The invention relates to an agricultural planting technology, in particular to a method for improving the yield and planting benefit of crops suitable for growing in heavy saline-alkali soil.
Background
About 9.54 hundred million hm is currently around the world2The saline-alkali soil occupies 10 percent of the land area and 7 percent of the cultivated land area, and the cultivated land area is about 1 to 2 million hm every year2The vegetation is difficult to grow in saline-alkali soil. In arid and semiarid coastal sea areas in the north of China, the heavy saline-alkali land and the treatable beach area are about 70 ten thousand hm2Is an important reserve arable land resource. The underground salt water resources in the regions are rich, the underground water level is buried between 1m and 2m throughout the year, and the mineralization degree of underground water in winter and spring seasons is as high as more than 10 g/L. The seasonal salt return of soil is caused by a dry, windy and strong-wind seasonal climate, so that the salt content of a plough layer of 0-30cm of soil in spring is up to 0.5-2%, most plants cannot grow, and only a few wild plants with extremely high salt tolerance, such as reed, suaeda glauca and the like, can grow sporadically. These heavy salt basesThe spring landscape of the land usually presents the 'alkali crust' of the white flowers, which is quite inhospitable. Therefore, local water and soil resources are utilized to fertilizer the thin salt to improve the soil fertility; the saline water is used for washing salt, the high-salt environment of soil is relieved, the technologies of losing weight, increasing efficiency, reducing salt and increasing yield and being suitable for the high-efficiency planting of crops are researched and developed, and the saline-alkali soil.
The oil sunflower is an oil sunflower, has the characteristics of short growth period, wide adaptability, strong stress resistance, high temperature resistance, low temperature resistance, drought resistance, barren resistance, easy management, high oil yield and low planting cost, and is an important oil crop planted in the obstructive barren soil. The cotton has the characteristic of saline-alkali resistance, can be planted in a large area in light and medium saline-alkali areas with the salt content of less than 0.28 percent, and creates an environment suitable for cotton seed emergence and seedling growth by scientific salt reduction measures for heavy saline-alkali soil. For this reason, techniques of applying fertilizer in winter and irrigating and freezing by using local underground saline water have been proposed to achieve desalting of the upper layer of soil. However, the method has the problems of large fertilizing amount, too early fertilizing time, application of only nitrogenous fertilizer and phosphatic fertilizer, no application of potash fertilizer and the like. The fertilizing amount not only wastes resources, but also aggravates soil salinization; too early fertilization time to match the nutrient demand of crops in the growing period also causes fertilizer waste and environmental problems;
due to the limitation of crops which can be planted in the heavy saline-alkali soil, pioneer plants which are extremely salt-tolerant are few and few, if any one of the crops is singly planted for more than three years, the yield is sharply reduced, and soil-borne diseases can occur. Therefore, exploring the crop rotation of the suitable crops in the heavy saline-alkali soil, together with a suitable soil conditioner and a weight-reducing synergistic technology is an important way for improving the barren heavy saline-alkali soil and improving the planting benefit of the suitable crops in the saline-alkali soil.

In addition, the invention fully utilizes natural light, heat, rainfall, underground saline water, saline-alkali soil and other climatic and natural resources, avoids the trend of benefiting, and realizes the green development and ecological safety of the barren saline-alkali soil.
Detailed Description
The method is suitable for coastal heavy saline-alkali land areas, is specific to coastal heavy saline-alkali land areas, and is characterized in that fresh water resources are deficient, the salt content of soil is more than 0.3%, no agricultural cultivation history is available for at least 50 years, and the temperature in winter is averagely lower than-3 ℃. And (3) extracting local underground salt water when the surface temperature is stabilized at-4 ℃ in winter in the last year before sowing, performing flood irrigation or spray irrigation on the surface, wherein the irrigation amount is 180-186mm, and the irrigated salt water is frozen quickly due to low-temperature freezing. And (3) immediately covering a film after the salt water ice melts and infiltrates in the spring of the next year, reducing the phenomenon that soil salt migrates upward along with water evaporation and surface accumulation, desalting and leaching the soil in the barren severe saline-alkali soil once, wherein the soil condition for sowing and seedling emergence of most crops cannot be met in spring, and pioneer crops such as oil sunflower suitable for short date can be sown only after rainwater is leached and desalted again when rainy season comes.
The fertilizer applied by the invention needs to strictly control the fertilizing amount, and the fertilizer variety selects the loss control fertilizer (such as 'heart-to-heart' loss control fertilizer) mixed with attapulgite, so that the fertilizer loss can be reduced, the fertilizer utilization rate can be improved and the fertilizer effect is long-lasting while the nutrient supply of cotton in the whole growth period is ensured; the secondary salinization of the soil is prevented, and the soil nutrient environment of the saline-alkali soil is improved. The inventionThe method breaks through the traditional method of not applying potash fertilizer in heavy saline-alkali soil, and reasonably matches the available nutrient N-P2O5-K2The proportion of O, and the application amount of the fertilizer is strictly controlled. Experiments show that the K/Na ratio of soil can be improved by applying a proper amount of potash fertilizer, and the K/Na ratio of crops to K can be promoted+Absorbing and reducing high content Na of plant to soil+Thereby reducing salt damage and improving the yield of the suitable crops. In addition, the fertilizing method of the invention is only to apply base fertilizer once before sowing, and no additional fertilizer is applied during the growth period of crops. The fertilizer is difficult to transport and absorb in the dry farming soil of the heavy saline-alkali soil compared with the water irrigation, the topdressing operation must be performed before the rain or in the rain, otherwise, the fertilizer loss rate is high, the topdressing effect is poor, and the rain-dispelling operation is unrealistic for farmers who lack the green and strong labor at present; secondly, the labor cost and the operation intensity are increased and the economic benefit is reduced no matter the soil is ploughed and disturbed for dressing or the surface is broadcast for application; the topdressing can also cause physical damage to the mulching film, and the high temperature in summer can cause soil salinity to quickly go upwards along with water evaporation, thereby increasing the salinity of a soil plough layer.
