Irrigation method for orchard

Abstract

The invention relates to an irrigation method for an orchard, which comprises the following steps: (1) ditching an irrigation ditch along the direction of planted fruit trees, wherein a distance between the irrigation ditch and sapling trunk is 50-80 centimeters or a distance between the irrigation ditch and grown tree trunk is 100-140 centimeters, the width of the irrigation ditch is 20-40 centimeters, the depth of the irrigation ditch is 25-35 centimeters and the length of the irrigation ditch is 50-100 centimeters, and (2) while irrigating the orchard at each time, injecting water into the irrigation ditch through a grassland filtering land, wherein water is fully filled at each time, thereby ensuring the effective water requirement of the fruit trees, preventing flourishing growth of the fruit trees in later period caused by excessive water, and being beneficial to promoting blooming and resulting rate of the fruit trees. The grassland filtering land can be used for filtering and accumulating the pollutants in the irrigation water, degrading and absorbing pesticides and heavy metal, purifying the irrigation water and protecting ecological environment of the orchard.

Description

1. Technical field [0001] The invention relates to an irrigation method for orchards, in particular to an irrigation method suitable for apple, pear, peach and grape orchards in northern arid regions. 2. Background technology [0002] Fruit trees need water during the growth period, so the irrigation method used in orchards is an important forestry production method; there is a certain limit to the water demand of fruit trees, too much or too little is not good. Soil is a complex of water, fertilizer, air, and heat. For good soil, each element of the soil has an appropriate ratio. If there is too much water, it will inevitably affect the other three aspects. If there is too much water, the air permeability of the soil will decrease. It will become worse, and the root system of the fruit tree will have poor breathing, and in severe cases, the root system will die; when there is too much water, it is difficult to increase the soil temperature, and the lower temperature is not ...

AI Technical Summary

Problems solved by technology

[0004] 1. Flood irrigation is common, resulting in waste of water resources; while drip irrigation and sprinkler irrigation require a large investment, it is still difficult for orchard farmers to implement. 2. Most orchards are managed with clear tillage on the ground, which causes soil erosion during the flood irrigation process, resulting in water and soil loss in orchards. 3 , A large number of pesticides and chemical fertilizers are used, resulting in the pollution of shallow groundwater and surface water in the orchard, which seriously damages the orchard ecology and leads to the accumulation of harmful substances, causing fruit quality and safety.
