How to water the dragon fruit?

How to water the dragon fruit? What should I pay attention to when watering dragon fruit? Netizens who have experience in dragon fruit planting are also invited to help introduce that dragon fruit has strong drought resistance and drought tolerance, but it does not mean that dragon fruit does not need watering, so the planting network has sorted out the watering methods and matters needing attention. The following detailed list is for netizens' reference. First, the importance of water to plants: water is the lifeblood of plant growth and an indispensable component of all organ activities. In the life activities of fruit trees, water plays a role in maintaining cell swelling and pressure, ensuring stomatal opening and carbon dioxide entry. All chemical changes in the body can only be carried out in the presence of water. The nutrients in the soil can only be absorbed and utilized when they are dissolved in water. More importantly, water is the necessary raw material for photosynthesis and the basis for the formation of yield. In addition, only under the condition of water can we maintain the transpiration of fruit trees, adjust the tree temperature, and ensure the transport of photosynthates and mineral nutrients. Therefore, in the cultivation of fruit trees, timely watering is an important measure to ensure premature, high yield and high quality. Second, the watering period of dragon fruit: before the fruit tree is affected by the lack of water, the watering period of dragon fruit should not be watered when the fruit tree has already had drought (such as wilting, fruit shrinkage). Judging whether it needs watering or not mainly depends on the soil moisture. Generally speaking, 60%-80% of the maximum soil water holding capacity is the most suitable for the growth and development of fruit trees. Dragon fruit grows in desert areas for a long time and has a strong tolerance for water shortage. In foreign countries, measuring instruments are generally used to measure soil moisture to guide irrigation. The irrigation period is determined not only according to the soil moisture, but also the climatic conditions and the growth and development stage of the fruit tree itself. Third, the role of watering dragon fruit in each period: 1. If there is enough water in the soil before and after germination to flowering, it can strengthen the growth of new shoots, increase leaf area, enhance photosynthesis, and make flowering and fruit setting normal, laying the foundation for high yield in the same year. In spring drought areas, this irrigation is particularly important. 2. The period of new shoot growth and young fruit expansion is often called the critical period of water requirement of fruit trees. At this time, the physiological function of the fruit tree is the most prosperous, such as the lack of water, the leaves take away the moisture of the young fruit, making the young fruit shrink and fall off. 3. During the period of rapid fruit expansion, this watering can meet the requirements of fertilizer and water for fruit expansion. But it is necessary to master the amount of water this time. 4. Before and after fruit picking and dormant period are in the arid area of autumn and winter, irrigation at this time can store enough water in the soil, contribute to the decomposition of fertilizer, and promote the growth and development of fruit trees in the next spring. After the last batch of dragon fruit is harvested in autumn and winter, it enters the dormant period, at this time, if there is proper irrigation, it can promote the growth of the plant and promote the branches to become fruiting branches as soon as possible. Third, the watering method and water quantity of dragon fruit: 1. Flood irrigation in areas with rich water sources and flat terrain, the whole garden is often irrigated. However, this method has a certain degree of damage to the soil structure, labor-consuming and time-consuming, and uneconomical, so it has been gradually reduced. 2. Border irrigation repairs the tree plate with the plant as a unit, or forms a long bed along the tree line, and diverts water into the tree plate or border when irrigation. This method saves water, is easy to manage, and is widely used. However, it will also damage the soil structure of the tree bed, resulting in the death of absorbing roots. 3. Hole irrigation when there is a lack of water source, 12 holes with a diameter of about 30 cm can be opened on the outer edge of the crown dripping line. The depth of the hole is appropriate not to hurt the root. Water is injected into the hole and filled after infiltration. 4. Furrow irrigation ditches are opened at a certain distance between two rows of trees, with a depth of 20ml / 30cm and a width of about 50cm. Generally open 2 per row, dwarf dense planting garden can also open one, the water into the ditch, gradually infiltrate into the soil. This method not only saves water, but also destroys soil structure less, so it should be advocated. 5. Drip irrigation is an advanced irrigation technology of mechanization and automation developed in recent years, which is a method of slowly applying water droplets or small water flow to the plant root region. Now it is gradually adopted in production. Drip irrigation has many advantages: for example, drip irrigation only moistens the soil layer and topsoil near the roots of crops, greatly reducing water evaporation; this system can be fully automated and minimize labor. Moreover, it can often supply water to the soil in the root zone, maintain the soil moist evenly, make it not too moist and too dry, and keep the soil in the root zone well ventilated at the same time, such as drip irrigation combined with fertilization, it can continuously supply root nutrients, which is most conducive to the growth and development of fruit trees and kill two birds with one stone. According to foreign reports, drip irrigation can increase the yield of fruit trees by 20% to 50%. However, the drip irrigation system needs more pipes, a large investment, a water tower and filtration system with a certain pressure, and the introduction of water into the main and branch pipes of the orchard, as well as the capillaries and emitters around the tree. And pipes and emitters are easy to clog, strict requirements of good filtration equipment. No matter which irrigation method is adopted, the amount of primary irrigation should not be too large or too little, and it is appropriate to soak through the soil of the main root distribution layer. In order to determine the amount of irrigation, the soil quality, the growth and development period of fruit trees, fertilization and meteorological conditions should be taken into account. It is generally believed that the minimum irrigation capacity is 60% of the maximum soil moisture capacity, and the ideal water capacity is 80% of the maximum water holding capacity. In addition, according to the long-term experience of fruit growers and technicians, it is considered that the irrigation is thoroughly, which is actually the most suitable amount of irrigation. Fourth, the drainage of the dragon orchard: the root of the dragon fruit is most afraid of anoxia, avoiding stagnant water, too much soil moisture, weakening air permeability, hindering the breathing of the root, seriously suffocating the active part, causing fruit drop, reducing fruit flavor, and even causing plant death. Therefore, in addition to water conservation and timely irrigation, we should also do a good job in flood control and other drainage work, build drainage ditches and floodways, and prepare for flood control and drainage in rainy seasons. The number and size of drainage ditches in the orchard should be determined according to the local rainfall, the strength of soil water retention and the level of groundwater level. In general, the drainage ditch in the dragon fruit orchard is about 1 meter deep. What environment is suitable for planting dragon fruit planting technology video
