Abstract
The invention relates to a method for planting a crop, in particular to saline soil water-free region water supply salt-leaching high-efficiency crop planting method. A pressure alkali water supply method by utilizing a plant to supply water and an all-film to cover storage water is adopted. Shortage of water resource is the biggest barrier that the saline-alkali soil can not be improved or utilized, the method in the invention starts with the key of solving a water source for high-efficiency crop planting, salt-tolerant and sea water-tolerant plants such as samphire and suaeda heteroptera are utilized to absorb moisture in soil in a no-water source region, transpiration principle of a plant is utilized to realize all-layer plastic membrane mulching, a mulching film is utilized to seal sea water-durable plants, rising gas hydrate is cooled to supply water to the root of the plant, meanwhile all-layer plastic membrane mulching is utilized, no water is leaked, and 80% of rainwater can be stored, when a crop is in drought, water is supplied in a drop irrigation way, the problem of water supply of the plants in the water-free saline soil is solved, and an innovation is provided for the water-free saline soil planting technology.
Description
One, technical field: the present invention relates to a method of planting crops, the crops method is efficiently planted in the anhydrous regional water supply desalinization of soil by flooding or leaching of especially a kind of solonchak.
Two, background technology: the plant growth of present anti-heavy saline is a global problem, so far not success, let alone be efficiently to plant crops, improvement at northern China border on the sea solonchak, basically all be the engineering improvement, popular is to ooze plumber's journey to change construction method, the improvement time is long, generally need the time more than 3 years, not only investment is big, and can't use in the area at no water source, China's border on the sea solonchak at present also not have the key reason that develops, mainly is the water supply problem that does not solve the saline land.
Three, summary of the invention: purpose of the present invention just provides the anhydrous regional water supply desalinization of soil by flooding or leaching of a kind of solonchak and efficiently plants the crops method.Traditional improvement kind method for planting mainly is that salt falls in row's alkali, what the present invention adopted is to utilize plant to provide water and full film to cover the pressure alkali method of supplying water of retaining, the shortage at water source is the biggest obstacle that utilization can't be improved in the saline land, the present invention starts with from the key that the present invention plants efficient crops from the solution water source, utilize salt tolerant sea water resistance plant sea covering at anhydrous source area, seawater Suaed heteropteras etc. absorb the moisture in the soil, utilize the rising principle of plant to carry out the holostrome plastic mulching, utilize ground membrane closure sea water resistance plant, cool off rising gas water, supply water to plant root, utilize the holostrome plastic mulching simultaneously, do not seep water and 80% of rainwater can be stored,, supply water with the mode of drip irrigation in crop when arid, having solved the water supply difficult problem of anhydrous salt soil district plant, is an innovation of anhydrous salt soil species planting technology.
Four, embodiment: spring is in the low-lying place of landform, by digging a cistern at 1: 20, height direction ditching, ridging by landform, before trench digging, spread plastic film earlier, space consuming half, soil in the ditch is placed on the plastic film, do the ridge, such purpose is to prevent that underground salinity from rising, plantation seawater Suaed heteroptera in the ditch, the sea covering, the rice grass, carrying out holostrome then covers, combine the water supply desalinization of soil by flooding or leaching with rainwater through plant transpiration water like this, progressively desalination, salt content is dropped to below 0.3%, at the end of May to July, can plant various non-salt tolerant crop vegetables, utilize full film to cover impermeable advantage simultaneously, just can begin to store rainwater after May, the normal time just can held water in enough whole year by the end of June, like this seedling stage crop need water period seldom, utilize rising water supply of salt tolerant sea water resistance plant corpus just can satisfy the needs of moisture in seedling stage fully, be in rainy season when the water demand of crop is big, the rainwater of available storage supplies water, by the combination of two kinds of water systems, thoroughly solved the desalinization of soil by flooding or leaching water supply difficult problem of the efficient crops of the anhydrous area plantation of strongly salined soil like this.
Claims (1)
1. the crops method is efficiently planted in the anhydrous regional water supply desalinization of soil by flooding or leaching of solonchak, it is characterized in that: be to select the water system of salt-tolerant plant for use as non-salt-tolerant plant, rainwater stores to supply water irrigates the irrigation new method that forms a whole set of, spring is in the low-lying place of landform, by digging a cistern at 1: 20, height direction ditching, ridging by landform, before trench digging, spread plastic film earlier, space consuming half, soil in the ditch is placed on the plastic film, do the ridge, such purpose is to prevent that underground salinity from rising, plantation seawater Suaed heteroptera in the ditch, the sea covering, the rice grass, carrying out holostrome then covers, combine the water supply desalinization of soil by flooding or leaching with rainwater through plant transpiration water like this, progressively desalination, salt content is dropped to below 0.3%, at the end of May to July, can plant various non-salt tolerant crop vegetables, utilize full film to cover impermeable advantage simultaneously, after May, just can begin to store rainwater, the normal time just can held water in enough whole year by the end of June, like this seedling stage crop need water period seldom, utilize rising water supply of salt tolerant sea water resistance plant corpus just can satisfy the needs of moisture in seedling stage fully, when the water demand of crop is big, be in rainy season, the rainwater of available storage supplies water, and like this by the combination of two kinds of water systems, has thoroughly solved the desalinization of soil by flooding or leaching water supply difficult problem of the efficient crops of the anhydrous area plantation of strongly salined soil.
