The object of the present invention is to provide a kind of flat film irrigation method, not only simple to operate, to pour water evenly, the water yield is controlled easily, and water-saving result is obvious, and it is few to expend man-hour, and can be in conjunction with irrigation fertilization, and the assurance crops later stage is fertilizer deficiency not.
The present invention is achieved in that a kind of flat film irrigation method, directly utilizes the existing channel diversion in irrigated area, the steps include: 1, rebuilds the field face, makes its maintenance level, and it is in 0.8 ‰ that error is controlled at the gradient; 2, covering film on the face of field with four limit perks of mulch film, is imbedded the low bank of earth between fields, forms the embanked field, and sows and beat uniform infiltration hole simultaneously; When 3, pouring water, water is introduced on the mulch film in embanked field by channel, according to the water requirement of crops, formed corresponding grade for profundal zone in the embanked field, when the water depth before the ridge, embanked field reaches the requirement degree of depth, water inlet is sealed, water is by infiltration hole infiltrating irrigation in soil.
This invention is owing to be trimmed to horizontal field face to the embanked field of covering film, in the embanked field sowing and beat the hole of seeping water after, when pouring water, easy and simple to handle, the embanked field is gone in diversion, on the face of embanked field according to profundal zones such as crop water requirement formation, only need to observe the water depth before the furrow ridge, need not to monitor the situation of pouring water of furrow tail, need not to control flow of inlet water, the depth of water reaches the requirement degree of depth, and the water inlet on the furrow ridge can seal.Both can save man hour of labour, and be not easy again to metal run out, because the infiltration hole that rationally distributes, make that ground moistening is even on the embanked field everywhere, water-saving result is remarkable, because of irrigation quantity does not run off, can be beneficial to the growth of crops in conjunction with irrigation fertilization, the present invention is applicable to the irrigation of various dry field farming things.
Fig. 1 is for planting the vertical view of the unit of pouring water in the furrow of the present invention, Fig. 2 is for planting the vertical view of the unit of pouring water on the ridge of the present invention, Fig. 3 is the pour water A-cutaway view of unit of the present invention, and Fig. 4 is the unit B-B cutaway views of pouring water of plantation in the furrow of the present invention, and Fig. 5 is the unit C-C cutaway view of pouring water of plantation on the ridge of the present invention.Below in conjunction with accompanying drawing the present invention is further described, a kind of method of flat film irrigation, can directly utilize the existing channel diversion in irrigated area, the steps include: 1, trimming field face, make its maintenance level, it is in 0.8 ‰ that error is controlled at the gradient, 2,2. 6. covering film with mulch film four limit perks 6., imbed the low bank of earth between fields on the face of field, form the embanked field 1., and sowing simultaneously, the dense planting crops are as the wheat class, the broomcorn millet cereal broadcast the embanked field 1. in, wide capable crops such as cotton, corn, Chinese sorghums etc. are broadcast on the furrow ridge and 2. go up, 6. beat uniform infiltration hole 4. at mulch film on, simultaneously, 1. also set up uniform additional infiltration hole 5. on the field face of afterbody in the embanked field, 3, when pouring water, water is introduced the embanked field, deliver to mulch film very soon with big flow and 6. go up, form the corresponding profundal zone that waits according to the water requirements of crops is temporary transient in 1. in the embanked field, water inlet can be sealed, water by the infiltration hole 4. with the seedling hole 3. and additional infiltration 5. infiltrating irrigation in soil of hole.
Embodiment: the method for irrigation on plastic membrance water and the method for flat film irrigation are relatively.
On the farmland under the equal clay fertilizer condition, carry out the contrast experiment:
1, the method for irrigation on plastic membrance water: use the method for irrigation on plastic membrance water on 300 mu of bar fields, the bar field gradient is 4 ‰, and film is built the ridge on face upper berth, field, form the embanked field, and sowing simultaneously, pour water needs 8 people at every turn, work and just can finish in two days, when pouring water, the head and the tail in embanked field all need the people to monitor, when pouring water layer forward when the embanked field afterbody also has a segment distance, just seal water inlet, make that remaining current continue to flow forward in the embanked field, up to the embanked field afterbody, but just occurring surplus water slightly accidentally overflows from ridge.400 cubic metres of every mu of ground irrigating water quota average out to are owing to can not cause crops later stage fertilizer deficiency in conjunction with irrigation fertilization.
