Understand the cultivation techniques of edible fungi and the selection of water-saving irrigation techniques in flower production.

The demonstration area of water-saving irrigation project in flower base is an efficient agricultural project built by saving water resources, promoting the sustainable development of agriculture and improving the basic production conditions of agriculture. Only by developing water-saving irrigation technology and taking the road of high efficiency and water saving can we achieve the goal of improving the utilization and output rate of water resources and increasing farmers' income.

According to the topographic and economic conditions of the project base, as well as the varieties and management methods of flowers planted, many kinds of water-saving irrigation projects can be selected, such as fixed sprinkler irrigation, semi-fixed sprinkler irrigation, reel mobile sprinkler irrigation, low-pressure pipeline irrigation, shed automatic micro-sprinkler irrigation, micro-irrigation belt irrigation and so on. For large-scale planting with many varieties of flowers and frequent irrigation, fixed and semi-fixed sprinkler irrigation should be selected. The conditions are relatively poor, the areas dominated by seedling cultivation can be irrigated by low-pressure water pipes, and the main pipes can be designed according to sprinkler irrigation conditions for future transformation. For the flower base managed by the company, due to the lack of manpower and centralized production, the reel sprinkler equipment can be used for irrigation. The use of protected cultivation, greenhouse planting and maintenance of flowers, micro-spray irrigation can be used. Some advanced irrigation model demonstration areas have been formed according to local conditions.

Take the flower base as an example, there are many kinds of flowers, and different irrigation modes are adopted as follows:

1. Fixed sprinkler irrigation

The fixed sprinkler irrigation mode is adopted on both sides of the flower corridor, which is also the main promotion form of the project area, which is suitable for large-scale planting and concentrated areas, and there are mainly low-stem flowers in the 200-meter area of the flower corridor.

2. Semi-fixed sprinkler irrigation

This is a kind of irrigation mode with less investment compared with the fixed sprinkler irrigation mode, which is mainly used in continuous planting areas, with decentralized management, diversified planting structure and relatively less investment.

3. Irrigation by buried low pressure pipeline.

Buried low-pressure pipeline irrigation is a traditional form of irrigation. first of all, its water delivery pressure is low, there is no high requirement for water quality, because the outlet flow is large, it is not easy to block, and the project cost is low. Because the branch pipe of this irrigation mode is convenient to move, it can meet the scattered flowers and meet the water requirements of different varieties. It is welcomed because of the low cost of the project, and its water-saving effect is not very high, but when the PVC pipe is buried, the pressure of the main pipe can be improved to prepare for the upgrading of the system to sprinkler irrigation system when economic conditions permit.

4. Micro-spray irrigation

This kind of irrigation form can be used in the low-pressure pipeline area, which makes up for the defect that the outlet of the low-pressure water pipe does not save water. Micro-sprinkler irrigation has the advantages of uniform spraying, good water-saving effect, wide promotion, and the seedlings of high and low bars can be used, and its advantage is less investment. but the recovery is relatively labor-consuming, and the service life is not long. However, micro-sprinkler irrigation is welcomed by small-scale planting and family horticulture, and the promotion effect is also relatively good.

5. Reel mobile sprinkler irrigation

The reel sprinkler irrigation machine with high degree of mechanization can adapt to the irrigation of different kinds of flowers. it is easy to operate and easy to move, and the sprinkler irrigation intensity and droplet diameter can be adjusted, so it is suitable for large-scale base production and saves time.

6. Automatic micro-irrigation in greenhouse

Medium and high-grade flowers generally choose to be carried out in the greenhouse, so the automatic micro-irrigation suitable for the greenhouse is selected here. This form of irrigation is suitable for a variety of medium and high-grade flowers and bonsai, seedlings, water-saving efficiency is high, but the investment is relatively large, but its high automation can save labor costs. The automatic micro-spraying is uniform and the atomization effect is good, and the application effect is good in several greenhouse demonstration areas in Qianling.

7. Telescopic sprinkler irrigation

Telescopic sprinkler irrigation is a new sprinkler irrigation technology, which has the characteristics of high spraying uniformity, convenient management, water saving and labor saving.
