The problems that in the severe drought field surface cracked ground, flooding irrigation water is seriously lost, the normal growth requirement of the rice cannot be met, and the effective utilization rate of the irrigation water is low are solved by utilizing the impounding reservoir and adopting a micro irrigation method such as point irrigation and sprinkling irrigation, the micro irrigation method is adopted to enable the irrigation water to be fully infiltrated into soil, draining of the irrigation water is greatly reduced, the utilization rate of the irrigation water is improved, rice growth is promoted, yield losses are reduced, the minimum precise irrigation in the rice drought period can be achieved, irrigation can be completed at one time, the utilization rate of water resources is improved, the limited water resources are used for solving the influence of the seasonal drought on the rice yield, a certain amount of water soluble fertilizer can be poured into the impounding reservoir and evenly stirred, the water soluble fertilizer and the irrigation water are jointly applied to the soil, and the utilization rate of the fertilizer is improved.
Description
Technical field
The present invention relates to agricultural irrigation technology, is a kind of paddy rice seasonal drought irrigation method specifically.
Background technology
China's Water Consumption in Agriculture accounts for 70% of national total water amount, more than reaching 4,000 hundred million m3, and China's Farmland Water availability and water use efficiency are all lower, wherein farmland irrigating water's availability is only on average 40%～45%, farmland irrigating water's production efficiency only has 1.0kg/m3 left and right, well below developed country 70%～80% and level more than 2.0kg/m3.And the paddy rice main cereal crops that are China, plant widely distributed, the about 2867hm2 of sowing area throughout the year, paddy annual production approximately 1.8 hundred million t, account for respectively China's cereal crops sowing area 29% and total grain output 40%, and in Rice Production process, water consumption is huge, accounts for 70% of agricultural water, even the south China paddy rice main producing region of relatively enriching in water resource, water resource to the restriction of Rice Production also clearly.And during paddy growth, rainfall and water resource spatial and temporal distributions are very irregular, distribute asynchronous with evaporation discharge, approximately 50% concentrate on for 4～June throughout the year, high temperature and little rainfall between Xia Qiu, 7～9 monthly evaporating capacities approach annual half, often occur seasonal drought, and some times, regional Rice Production seasonal drought are serious, in recent years, South Rice Region of China seasonal drought takes place frequently and retransmits rising.Arid has become the Major Natural Disasters that causes study of grain yield fluctuation, directly threatens national food safety.
Paddy rice is to irrigate rice as main, and paddy growth needs to irrigate season, and existing irrigation method is mainly to utilize the flood irrigation of irrigation canals and ditches ground.Under paddy soil does not have Cracking Condition, adopt the tillage pan of ground flood irrigation due to rice field densification, rice field leaks little with water percolating capacity.But there is seasonal drought during Rice Production time, rice field cracking, crack penetrates tillage pan, and while adopting ground flood irrigation, a large amount of irrigation waters flow out from tillage pan, and irrigation water availability is very low, drought resisting poor effect.Paddy growth is more responsive to lack of water, and lack of water mainly causes growth period duration of rice shortening, plant to diminish, and ripening rate reduces, thousand kernel weight declines, biomass declines, and causes the paddy rice underproduction even to be had no harvest.Irrigation method intermittent irrigation in Rice Production, moistening irrigation, semiarid cultivation etc. at present, these irrigation practices play a significantly greater role to saving Rice Production water, but all irrigation methods are all to pass through irrigation canals and ditches, enter land for growing field crops, adopt ground flood irrigation, irrigation efficiency of water application is low, and need to have the supporting of sufficient water source and irrigation canals and ditches just can carry out.Seasonal drought phase water source is difficult to guarantee, and irrigation canals and ditches engineering aging, one meets arid, without source of irrigation water, field face lack of water causes dry and cracked, especially severe drought causes field facial cleft seam to increase intensification, crack penetrates tillage pan, even if having rainfall or pour water, all can directly run off in a large number by crack in the later stage, cannot meet paddy growth demand, and irrigation efficiency of water application is very low, can cause the paddy rice underproduction even to be had no harvest in the serious region of seasonal drought at all, therefore, need new irrigation method to solve that flood irrigation efficiency of water application in ground is very low, the problem of drought resisting weak effect.
Summary of the invention
The present invention is mainly for problem low, drought resisting weak effect for Rice irrigation water conservancy during Rice Production seasonal drought, adopt the micro-irrigation methods such as drip irrigation and spray irrigation, allow irrigation water be penetrated into soil, effectively absorbed and rice in utilization by soil, significantly reduce the loss of irrigation water, improve irrigation water utilization ratio, reach and irrigate drought resisting object, the final effect increasing income that realizes.
For achieving the above object, the technical solution used in the present invention is: a kind of paddy rice seasonal drought irrigation method, comprises the steps:
1) build cistern, in the middle of every 10～20 mu of paddy fields, set up the height 10m of 30～40 cubic metres, the cistern that length and width are 2m × 2m, bottom and surrounding at cistern are set up active filters net, and connect several water-supply-pipes at cistern sidewall by the punching of 10cm place, bottom;
2) pipe laying, water-supply-pipe is routed to every plot of paddy field, and water meter and valve are set simultaneously on the water-supply-pipe of every plot of paddy field; Press between paddy rice row distance and lay an irrigate band or spray irrigation bands every 4 row, on dropper band or spray irrigation band, every 4～6 strain paddy rice, a dropper head or shower nozzle are set, between water-supply-pipe and irrigate band or spray irrigation band, be communicated with by three-way pipe;
3) between the seasonal dry season of paddy rice, be open at the conduit pipe valve on limit, rice field, start to drip and irrigate.
In the present invention, cistern utilization collection rain device utilizes rainfall retaining to greatest extent, also can fetch water from water source.
The present invention can install water pump on water-supply-pipe, for increasing the hydraulic pressure on dropper head, realizes sprinkling irrigation.
Useful technique effect of the present invention is:
(1) utilize cistern, adopt the micro-irrigation methods such as some fillings, sprinkling irrigation, solve the face cracking ground flood irrigation of severe drought field, irrigation water loss seriously, can not meet the problems such as paddy rice normal growth needs, irrigation application efficiency are low; Allow irrigation moisture be penetrated into soil, significantly reduce the loss of irrigation water, improve irrigation water utilization ratio, promote the loss of paddy growth and minimizing output, realize paddy rice and arid minimum flow Precision Irrigation, once complete irrigation, improve water utilization rate, solving arid by limited water resource affects Rice Production.
(2) the present invention also can, according to the fertilizer demand of paddy growth, pour a certain amount of water soluble fertilizer into cistern, stirs well evenly, is manured into soil together by irrigation water, dissolves and carries out irrigate band drip irrigation or spray irrigation band sprinkling irrigation by irrigating pond, improves utilization rate of fertilizer.
