Green energy mountain dry agriculture new irrigation system diagram

Process: water source (reservoir water/road rainwater collection/well water) → photovoltaic pumping station → upper water pipe → high anti-evaporation reservoir → field water distribution network → ground outlet pile → water distribution soft belt → drip irrigation belt under the film

One of the core technologies: zero water charge water extraction (photovoltaic power generation pumping)

1, system composition: photovoltaic array, photovoltaic water pump, pump special inverter, water pipe.

2, principle: absorb solar radiation energy, the photovoltaic array output direct current into alternating current, drive the pump pumping, so that it is ready to use.

3. Features:

Zero water charges for irrigation, a veritable green agriculture;

There is no need to set up high voltage lines and install transformers, which provides a model for supplementary irrigation of dry cropping in mountainous areas without grid coverage.

By using the APP programming software, the operation of the pump station can be controlled remotely by the mobile phone, so that the operation is unattended and the automation in the agricultural production process can be fully realized.

Modular structure, short construction period, small investment, low operating costs.

Core technology 2: Large open anti-evaporation reservoir (suitable for supplementary irrigation of small grains in dry farming)

The water storage capacity of the reservoir is large, which is suitable for regulating water storage in arid areas across seasons, so as to achieve "autumn water and spring water, abundant water and drought water", watering the seedling water, life-saving water and yield-increasing water of small cereals and other dry crops;

Reservoir combination mode:

Sedimentation tank + reservoir: collect rainwater from roads and courtyards, and then flow into the reservoir for storage;

Reservoir: the source of water is diverse, can be dam water, road water or well water, and the evaporation can be reduced by about 85% after the installation of floating and falling evaporation prevention system;

According to the location, it can be divided into high cisterns and field cisterns, and the irrigation water can be stored in the field of the irrigation area as far as possible, so that the water does not panic to the field and improves the irrigation guarantee rate.

Core technology 3: Prefabricated scalable PE reservoir (suitable for mountain terrace fruit tree irrigation)

The prefabricated expandable reservoir is a combination of finished PE water storage tanks buried under the frozen soil layer. It is a kind of irrigation storage equipment specially customized for the irrigation of fruit trees in mountain terraces. According to its function, it can be divided into two types: high level pool and decompression pool.

The project cost is low, which is about 40% of the cost of concrete reservoir;

Modular structure, short construction period, is one tenth of the construction period of concrete reservoir;

Food grade polyethylene is used as raw material of water storage tank, non-toxic and harmless, and the stored water can be used as drinking water for humans and animals;

No construction waste, green environmental protection, reusable;

According to the irrigation area, the water tanks can be connected in series or in parallel, and the reservoir volume can be expanded in the later stage.

In the northern Shaanxi mountains, the mountain gully is deep, the terrain is steep, the construction of concrete cistern, the material needs to be reversed twice, the need to build temporary construction roads, and the assembly cistern installation is simple, the construction of the mechanical equipment required less types.

Practical technology: Popularization of inadequate irrigation technology

The core of the theory of inadequate irrigation is that the irrigation water cannot fully meet the water demand of the whole process of crop growth and development, and only irrigates the key water in the critical period of the crop, does not pursue the highest yield per unit area, allows a certain limit of yield reduction, and strives to maximize the irrigated area and have an ideal total yield. In drought and water shortage areas, it is necessary to extend agricultural irrigation and apply inadequate irrigation technology.

Special fruit tree irrigator irrigation (suitable for mountain apple plant by plant hole irrigation) :

Under the condition of incomplete irrigation, the key water was only irrigated twice during the whole growth period of the fruit trees, that is, 45 liters of post-flowering water per tree and 50 liters of fruit expansion water per tree.

Features: Irrigator large diameter, not easy to plug; There is clear water flowing out, in line with the traditional irrigation habits of farmers; The moist area was large, and the capillary roots absorbed a wide range. It is not easy to produce surface runoff and deep leakage; Simple operation, convenient management; The fertilization process is simple and uniform, which can save a lot of fertilizer and inhibit the breeding of weeds between fruit trees.

Dry small grain (millet) drip irrigation:

In general drought years, under drip irrigation conditions, the key water is usually irrigated 2-3 times. The first time is the seedling water sown in early May every year, and the irrigation water per mu is about 3-5m³. The second is the booting water in mid-July every year, and the irrigation amount of mu is about 10m³. In the case of abundant irrigation water, the irrigation water of grain grouting water is about 10m³ per mu.

Drip irrigation technology in Yulin area has been promoted for many years, the technology is mature, favored by farmers.
