First, the technical measures adopted for planting Shatang orange on the slope
Irrigation
The most important feature of slope land is that it is not conducive to the conservation of water and soil. Therefore, the first problem to be solved in realizing the cultivation of sand and oranges on slopes is to use existing water sources to ensure the growth of sand oranges. At present, the more popular irrigation technologies are flood irrigation, pipe irrigation, and drip irrigation. We can learn from the successful experience of the successful promotion of cotton drip irrigation technology in China, and try to use it in the cultivation of sand oranges on the slopes. Drip irrigation technology is a new type of irrigation technology. It is mainly through the drippers on the trunk pipe, branch pipe, and capillary tube. Under the effect of low pressure, water is often dripped slowly, and the filtered water, fertilizer, and other chemicals are directly supplied to the soil. An irrigation system. Compared with the traditional irrigation method, it does not need to spray water or ditches. It only lets water seep out under the effect of gravity. It passes through the capillary into the soil and drops into the water near the root of the crop to keep the soil in the root of the crop. Optimum humidity. Due to the small drip flow and slow infiltration, it is the most efficient water-saving irrigation method.
2. Water retention
As the fruit fields are mostly distributed on hilly slopes with large slopes, the slopes are relatively large. Local farmers have not done any sort of processing along the slopes. Some of them have treated the slopes a bit and have treated them with narrower terraces for cultivation. Not enough, the width of the terrace is not only insufficient, but there is still a certain degree of slope, farming is difficult, and soil erosion is easily caused. In order to solve this problem, it is necessary to plan the construction of the terraces and plant the contoured crops on the ladders so as to reinforce the soil.
2.1 Creating a Biohazard
Planting crops on the slopes of the orchard to form a fence. According to the orchard slope, a biological fence can be planted every 5 to 15 meters. Each biological fence is about one meter wide and can be planted in one to two rows. Two types of hedges can be created, one is to grow an economic hedge, and the crop itself has a certain economic value. It can also reinforce the soil. For example, day lily is a good choice. The day lily has a dense root system with strong perennial roots. Strong solid earth function. Another type of hedge is the use of local wild mango grasses, which are dwarf herbs that are perennial, can adapt to harsh natural environments without input, and have a solid-soil retention effect.
2.2 orchard cover grass
After the straw-mulching, the soil moisture evaporation of the orange orchard was significantly reduced, the effect of water conservation and drought resistance was obvious, and runoff rarely occurred in the event of heavy rain, which greatly reduced the water and soil loss. The thickness of the orange orchard cover grass is 15-20 cm, so that the whole park can be covered with 1000-1500 kg of grass per mu. Where there is insufficient grass source, only the tree plate can be covered, but the thickness must meet the requirements, otherwise it is not conducive to water conservation. Before covering, it is best to plow and expand the hole. Dig a 60-100 cm deep ditch under the edge of the canopy, bury a certain amount of grass and apply a certain amount of human waste water, water it properly, and then cover the grass.
3. Water and fertilizer integration technology
The technology of water and fertilizer integration is a new type of agricultural technology in recent years. Its working principle is: Dissolving solid or liquid fertilizer in water at a certain proportion. Under the action of pressure system, water irrigation and fertilization will be combined. For one. Compared with traditional methods of irrigation and fertilization, fertilizer and water are prepared according to a certain proportion, and the needs of nutrients are different in different stages of crop growth. Water and fertilizer integration can be reasonably proportioned to this situation. Thus, both Can save fertilizer, but also make the crop grow vigorously. The water and fertilizer integration technology is based on drip irrigation technology. Only on the basis of drip irrigation technology, coupled with the use of soluble fertilizer, this technology has higher requirements for fertilizers, preferably liquid fertilizers. If it is a solid fertilizer, it must have high water solubility.
Second, the prospects for the development of sloping land sugar sand orange
Although shatangjue has good adaptability, it is difficult to cultivate shatangjue for irrigation and soil without fertile land, and the technology of diverting the slopes into terraces, drip irrigation technology, and integrated management of water and fertilizer can solve this problem. To improve the conservation of soil and water and meet the growing demand for shatangju citrus, the planting area of ​​shatangjue will expand. Because Shatangju has a good prospect of planting, and it can introduce technologies such as changing the slopes into terraces, drip irrigation technology, and integrated management of water and fertilizers, it can meet the conditions for growing shatangju citrus, so large-scale cultivation of shatangju can be realized. It will bring about the development of a series of industries, such as the tourism industry and the product processing industry, so as to broaden the sales channels for Shatang oranges and increase the sales volume of shatangju in order to continuously promote the continuous development of shatangju.
