Description

Foggara

Technical field

The utility model relates to a kind of foggara being used for irrigating crops.

Background technology

Crop growth needs moisture, does not have water just can not grow, and must water when rain lacks arid.Present drought resisting, what generally adopt is traditional surface irrigation method, have sprinkling irrigation, also has purling, allows water flow along ridge exactly.There is following disadvantage in these irrigation methods: 1. water on the ground, and inevitably shone by sunlight and shine, moisture evaporation causes waste; 2. if hillside fields is irrigated, water is poured on eminence, and water is low-lying by flowing to rapidly, and at this moment the moisture that obtains of eminence is little, and the water at low-lying place is have more than is needed.The part that crops do not absorb, has two whereabouts, and one is that sunlight evaporates according to shining, and two is the depths that permeate the ground.

Summary of the invention

The purpose of this utility model to adopt foggara, make water neither by sunlight according to shining, do not allow it flow to rapidly low-lying yet, also do not allow the depths that permeates the ground that it is too much.For this reason, the utility model adopts foggara flood irrigation, exactly water pipe is embedded in below ground, the degree of depth at the root system position of crops, by the soil of proportion of crop planting on water pipe.Before pipe laying, first beat on water pipe and make many apertures, allow water slowly ooze out from aperture, absorbed by crops.Described water pipe can be laid on immediately below crops, and each ridge crops can lay a water pipe, also can lay 1-100 root, and every root 1-100 rice is long.Described water pipe also can be laid on the below ground between two ridge crops, namely in the oblique below of crops.Aperture on described water pipe can be circumferentially 2,3,4,6 rows at water pipe, and also can be 1-20 row, be 5-50 centimetre in the distance in length of pipe direction between Kong Yukong.On a water pipe, all aperture area sums can not exceed water pipe internal diameter cross-sectional area.

Water can be delivered to the root of crops by the utility model easily, because at below ground, so can accomplish not shone by sunlight to shine, again because be aperture infiltration, it can not flow to rapidly low-lying, also because the aperture gross area is less than water pipe internal diameter cross-sectional area, so the crops of eminence also can be irrigated preferably, also because be aperture flood irrigation, so the water yield being seeped into deep under ground greatly reduces.Like this, both decreased the waste of the water yield, the crops of Shi Gao Gang Chu have been got back effective irrigation, also improve irrigation efficiency.Although laying foggara will increase some costs, lays a water pipe, be not only use 1 year, can use 2-5, it is not high that average calculation carrys out cost.

Embodiment

As shown in Figures 1 to 4, a kind of foggara of irrigate crops, be mainly laid on by the water pipe 3 with aperture 4 immediately below crops 8 or oblique below, the degree of depth of water pipe 3 is at the root system position 6 of the crops 8 on ground less than 7.The head end of water pipe 3 is connected to the funnel 1 being convenient to pour water in water pipe, and the tail end of water pipe 3 has the stopper 5 of the jam-pack mouth of pipe.Water pipe can be laid on immediately below crops 8, or 1, or 1-100 root, every root 1-100 rice is long.Water pipe also can be laid on the ground less than 7 between two ridge crops 8.Aperture 4 on described water pipe 3, can along water pipe circumferentially, or beat and make 2,3,4,5,6 rounds, or beat and do 1-20 round, is being 5-50 centimetre along the distance on length of pipe direction between Kong Yukong.Its internal diameter cross-sectional area of described water pipe 3 must be greater than the summation of all aperture 4 areas on water pipe.

As shown in Figure 1, water pipe 3 is laid on immediately below crops 8, and a water pipe is laid on a ridge, and 10 meters long, and water pipe head end is connected on funnel 1, is positioned on tripod 2,50 centimetres above ground level, tail end stopper 5 jam-pack of water pipe.Water pipe is in along the circumferential direction four sides punching, and every face one is arranged, and is being 25 centimetres along the distance in length of pipe direction between Kong Yukong.The internal diameter cross-sectional area of water pipe is greater than the summation of all aperture area on water pipe.The degree of depth of water pipe 3 is at the root system position of ground less than 7 crops 8.

As shown in Figure 2, water pipe 3 is laid on immediately below crops 8, and 20 water pipes are laid on every bar ridge, and every root 20 meters is long.The head end of water pipe 3 all connects funnel 1, is positioned on tripod 2,100 centimetres above ground level.The tail end of water pipe all uses stopper 5 jam-pack, does not allow water flow out from pipe ends.Water pipe 3 along the circumferential direction four sides punching, every face one is arranged, and is being 25 centimetres along pitch-row on length of pipe direction.The water pipe degree of depth is at the root system position of crops in underground.The internal diameter cross-sectional area of water pipe is greater than the summation of all aperture area on water pipe.

As shown in Figure 3, water pipe is laid on the centre on two crops ridges, and in the oblique below of crops, the degree of depth is at the root system position of below ground.10 water pipes are laid on every bar ridge, and every root 25 meters is long, and the head end of water pipe 3 connects funnel 1, by tripod 2, and 100 centimetres above ground level.Tail end stopper 5 jam-pack of water pipe.Water pipe evenly makes a call to 6 rounds in a circumferential direction, and between Kong Yukong, on length of pipe direction, distance is 30 centimetres, and the internal diameter cross-sectional area of water pipe is greater than the summation of all aperture area on water pipe.We calculate the length of a downcomer 3 now: the interior diameter 24 millimeters supposing water pipe, radius 12 millimeters, hole diameter 1 millimeter, radius 0.5 millimeter, then water pipe internal diameter cross-sectional area=π r ²=π × 12 ²=144 π, aperture area=π r ²=π × 0.5 ²=0.25 π, water pipe cross-sectional area is divided by π ÷ 0.25 π=576, aperture area=144, and namely water pipe cross-sectional area is 576 times of aperture area, water pipe can spile less than 576.The punching of 6, this water pipe, every face one round apart from being 30 centimetres in the longitudinal direction, one section of water pipe of 30 centimeter length exactly has 6 apertures, 576 ÷ 6=96 (segment).30 cm x 96=2880 centimetres=28.8 meters, leave surplus and get 25 meters.Namely interior diameter be 24 millimeters thick, the water pipe of 25 meters long can keep supplying the aperture infiltration that 500 diameters are 1 millimeter, can irrigate the proportion of crop planting ridge of 25 meters long.

As shown in Figure 4, irrigate acclive farmland with water pipe, water pipe is laid on immediately below crops, and the degree of depth is at the root system position of subsurface crops.Article one, a water pipe is laid on ridge, and the head end of water pipe 3 connects funnel 1, by tripod 2,50 centimetres above ground level, is placed on one end that physical features is higher.For making eminence and lower water balance, water pipe is in physical features lower ground section two sides punching, namely a circumference makes a call to two rounds, in four sides, the location punching that physical features is higher, namely a circumference makes a call to four rounds, and the punching of three, middle location, makes a call to three rounds, and Kong Yukong is 25 centimetres in the distance of length direction, be equal.Because the pressure in lower water pipe is large, water outlet is fast, and eminence pressure is little, and water outlet is slow, so will reduce the apopore of lower, makes the water yield of high lower obtain equilibrium.The internal diameter area of water pipe is greater than the summation of all aperture area on water pipe.

During operation, before Planting Crops, first in the place of laying water pipe, open the ditch that arrives crop root position, water pipe is layered in ditch, bassets in the one end connecing funnel, first the mouth of pipe is wrapped, do not enter soil when not connecing funnel.Other end stopper jam-pack, is embedded in soil.For ensure aperture infiltration, first fill out one deck sand grains during pipe laying, 2-3 cm thick, after fill out fine earth, do not allow large clod that water pipe is flattened.To planting season, Crop Species on top.

During use, the one end of basseting at water pipe connects funnel, and by tripod, 30-200 centimetre above ground level, just can pour water in bucket in the past.Irrigate 1 time or 1-2 day or 3-5 day, be finished rear stopper and the mouth of pipe is stoppered.

In sum, the narrow meshed foggara of the utility model, water directly can be delivered to the root of below ground crops, for crop absorption, effectively preventing evaporating according to shining of sunlight, having stopped surface, hillside fields irrigation water and having flowed to rapidly low-lying phenomenon generation, by the control to aperture quantity on water pipe, the water yield at farmland height Gang Chu and low-lying place is made to obtain equilibrium, again because be aperture flood irrigation, so also do not have the too much water yield to permeate the ground depths.In a word, the utility model, both saved with water, turn improving efficiency, even if increase some costs, is also to one's profit.
