Abstract
A permeating irrigation method features that the straw and stalks of crops are buried into ground by a certain depth and the hidden pipeline embedded underground is used for permeating irrigation. Its advantages include saving water increasing organic substance of soil for higher yield,and improving soil.
Description
The present invention relates to the also method of field infiltrating irrigation of a kind of crop stalk, be mainly used in conserve water resource and crop genetic resource aspect.
China's crop stalk quantity is big, it is wide to distribute, be the by product of agricultural production, also be important living resources, it mainly is that straw is pulverized that the existing utilization of China is returned crop stocks to the field, and ploughs and covers underground, but such method curing time is long, and is influential to the crops of plantation.Also having a kind ofly is " crossing also field of abdomen ", utilizes exactly that grain, straw are raised pigs, cowboying, pig manure, cow dung field also then, and this method is a kind of effectively field method also indirectly, weak point is that crop stalk can not direct returning to farmland.
The water resource utilization of China is along with the development of the development of the national economy more and more seems important, and now a large amount of water conservancy constructions play great role in the water resource utilization.Water seeks its own level, the thinking that stores rainwater is often established reservoir at the hypsography low-lying place now, and then water is flooded with power, carry and irrigate use, China's western mountainous areas particularly, great lot of water resources is taken advantage of a situation and is flow to the east, flow into the sea then, cause the great lot of water resources waste, also can cause disasters such as mountain torrents, floods, and the mountain area people are poor because of lack of water.Allow water resource keep its high potential energy position is the new starting point that we build water conservancy projects as far as possible, rain falls from the sky, own resources dewater, energy resource also should use as far as possible, keeps the high as far as possible potential of water resource, does not allow it run off, to mountain area, desertization area particular importance, do not allow its run off on the ground, undergroundly do not allow its run off yet, make it be in position and the height that needs as far as possible.
The present invention be directed to the weak point that prior art exists, also field and afflux utilize natural rainwater to carry out the method for infiltrating irrigation to invent a kind of crop stalk.
The present invention finishes the work like this: water conservancy construction is carried out in the farmland, store the dark water channel (also can claim underground reservoir) or the ground kiln of natural rainwater according to landform design afflux, the specus of these storing natural rainwater or ground kiln all are located at the high relatively place of physical features, these underground dark water channels or ground kiln are connected with the sub-irrigation closed conduit of crop stalk formation under being embedded in the farmland, be provided with gate at interface, the control infiltrating irrigation water yield and the afflux water yield.Be embedded in the closed conduit that the underground crop stalk in farmland forms, be provided with main closed conduit and prop up closed conduit, infiltrating irrigation face formation infiltrating irrigation system according to different demands, they have two effects, the one, arrive farmland every nook and cranny by this infiltrating irrigation system with the water infiltrating irrigation with the rainwater of afflux or the water of irrigation dry days, the 2nd, the rainy day also can be flowed back to dark water channel or ground kiln with the superfluous water in the soil by these infiltrating irrigation systems, natural rainwater is stored, and not allowing natural rainwater run off wastes, and drains flooded fields.Kanat or ground kiln are equipped with the overflow siphunculus and communicate with one another, and unnecessary water is discharged in surface reservoir or the lake goes, and the amount of capacity of underground dark water channel or ground kiln designs according to the scope and the infiltrating irrigation water consumption of institute's infiltrating irrigation, reaches economical rationality as far as possible.
Crop stalk is imbedded the underground degree of depth and can be designed according to being planted in the ground crops root system growth degree of depth, can reach the closed conduit road that crop stalk forms with root system before being planted in ground crops maturation, the nutrition that can absorb rotten crop stalk formation fertilizer is standard, being embedded in underground crop stalk can tie bundled also can loosing and bury, the diameter of bundle is according to the infiltrating irrigation water yield, area, the infiltrating irrigation time is designed, infiltrating irrigation system is made up of main closed conduit and a closed conduit and infiltrating irrigation face, at a closed conduit end, can bury crop stalk according to demand and form infiltrating irrigation face, can increase like this and use the also quantity in field of crop stalk.It is big more to be embedded in underground crop stalk amount, and infiltrating irrigation speed is fast more, and it is many more that the back soil that rots in the future includes fertilizer, but labour cost will be higher relatively.According to experiment, the straw of wheat is embedded in and just can rots into fertilizer in underground about three months.At this moment farming also needs a large amount of fertilizer, promotes ripe fructufy, so the base manure that the crop stalk of burying is equivalent to bury.The back sub-irrigation closed conduit infiltrating irrigation speed of rotting diminishes, but crops when ripe the water yield of required infiltrating irrigation relatively also littler.When following stubble is planted for the second time the crop stalk of burying for the first time ploughed under surface soil, increase soil organic fertilizer content.Be embedded in underground crop stalk winter and can also keep ground temperature.
In order to make soil obtain equal permanent nutrient, the crop stalk composition of burying is selected, after imbedding underground rotting, the composition of can effectively improving the soil, the nutrient component in soil can be controlled, in brief, crop stalk also field can be divided into common also field and control also field, common also field is exactly that just can to imbed underground at once be the infiltrating irrigation closed conduit for crop stalk behind the results crops, control also field is exactly different with plantation crops or crop demand according to the difference of soil composition, add some nutrient components or contain the crop stalk of these nutritions, trees or other plant are imbedded underground formation infiltrating irrigation closed conduit, thereby reach the requirement of improving the soil and increasing production.
The present invention compared with prior art has following advantage: the present invention uses also field of crop stalk in a large number.Increase the development and use of crop genetic resource greatly, according to data, the every mu of also field crop stalk 300-500 kilogram of ploughing.Can produce more food more than 25 kilograms, return crop stocks to the field in continuous 3 years, then can increase soil organic matter 0.2-0.4 percentage point.Also have data to show, crop stalk is gone back 1000 kilograms in field for every mu, and the back soil that rots is equivalent to increase by 24 kilograms in nitrogen, 21.4 kilograms in phosphorus, 18 kilograms in potassium.The present invention is used for infiltrating irrigation closed conduit road because of the crop stalk of going back the field, saved the cost of infiltrating irrigation, quicken the rotten time of crop stalk, the crop of smooth then basically crop stalk, the plantation same period down just can be used the fertilizer net of the crop stalk formation after rotten.Can reach the purpose of volume increase, can also keep ground temperature winter, grows up in order to crops.
Infiltrating irrigation is present up-to-date a kind of irrigation method, big flood irrigation water consumption reaches more than 1000 cubic metre for every mu, more than 500 cubic metre of the every mu of water consumption of spraying, the drip-irrigation water amount is also wanted more than 700 cubic metre for every mu, infiltrating irrigation is the minimum and the most effective a kind of irrigation method of water consumption, there is high gesture position in the present invention with natural rainwater, can form the gravity flow infiltrating irrigation, the conserve water resource, labor savings and fund, reduce agricultural cost, treasure sky and fall a fresh water, keep this potential energy that drips as far as possible, allow sky fall each rainwater and benefit for the mankind.
