High-yield Cultivation Management Techniques of Greenhouse Watermelon in Early Spring Facilities

Amaranth is actually a spinach that we often eat, and it tastes delicious. Today, Huinong.com has a chat with you about the technology of high-yield management of the early-season facilities, from the perspective of variety selection, greenhouse management, and seed screening.

1 variety selection

For the selection of early spring greenhouse rot variety, two varieties are generally preferred, one is bamboo leaf water spinach and the other is willow water spinach, because these two kinds of water spinach have strong ability to resist drought and cold. The water spinach of the willow leaves is greenish white, the leaves are willow-like and dark green, and the most prominent features are soft texture, less fiber and sweet taste. In addition, it grows rapidly, is resistant to cockroaches, heat, and does not climb, and is suitable for cultivation in various parts of China. Bamboo leaf spinach, originally introduced from Thailand, is strong in summer and suitable for high-density cultivation. It is most suitable for planting in spring and summer in the southern towns and towns. It is characterized by strong flavor and crisp taste.

2 seed screening and seedling

First of all, the seeds of the spinach should be processed before planting, because the typical characteristics of the seeds are that the texture of the skin is relatively thick and too hard, which will cause the germination process to be relatively long. It is necessary to soak the spinach seeds with moderate warm water, and also have strict requirements on the air humidity. If the humidity is too high, the spinach seeds will rot, and then they will be placed in the germination box to "pull the seedlings". Furthermore, seedlings provide loose and fertile soil for the growth of spinach seeds, then spread the seeds at appropriate intervals, watering them regularly, giving enough light, and then turning the soil in the later stages of the seedlings, according to the different conditions of the seedlings. Fertilize and spray nutrient solution.

3 greenhouse management

High-yield cultivation of water spinach is achieved by means of greenhouse management. The management of greenhouses is to place brackets on a certain area of ​​land, and to build up the steel members, which are in the shape of a parabola. After the steel frames are fixed, they are coated. The so-called filming process is to lay a plastic film with a thermal insulation effect. In the early spring, the temperature of the weather is gradually warming up. The management of the greenhouse is to ventilate the air at a fixed time every morning. Water should be properly watered every day. The thermometer should be used to measure the temperature in the greenhouse. If the temperature is unstable or high, the temperature will be unstable. Measures should be taken to control and make photosynthesis work better with the help of greenhouses. It can be seen that the management of greenhouses can provide the necessary conditions for the high-yield cultivation of water spinach, which should attract extensive attention and attention.

4 Fertilization and water management

For the high-yield cultivation of greenhouse rotins in early spring, strict fertilizer management should be implemented. The harvesting of the spinach is not completed in one time, but the topdressing is carried out after the fertilizer is applied. Fertilizers and moisture have different requirements at different stages. For fertilization, in the early stage of high-yield cultivation of water spinach, it is necessary to dilute less than 15% of the fertilizer and nutrient solution; in the middle stage of the spinach seedlings, 20% urea and 40% compound fertilizer should be applied. For water, the characteristic of water spinach is that the water demand is very large, but after pouring an appropriate amount of water in the early stage, the watering in the middle period is less, so as to avoid the production being reduced due to too moist. Therefore, it is necessary to properly control the requirements of fertilizer and water for high-yield cultivation of greenhouse vegetables in early spring.

5 Temperature and humidity management

For the high-yield cultivation of greenhouse rotins in early spring, there are also very strict requirements on temperature and humidity. The management of temperature and humidity is generally inextricably linked with the overall situation of the weather. The temperature of the spinach during the germination should be constant at 23 ~ 30 ° C, the higher temperature in the early stage is conducive to the growth of the spinach, the intermediate temperature should be appropriately reduced, generally the most suitable temperature is 25 ° C, which refers to the daytime temperature. The nighttime temperature must not be lower than 3 °C. In terms of humidity, the spinach is not a wet vegetable variety. The spinach is most likely to grow in a humid and low temperature environment, which requires that the humidity should not be too large. Moreover, the growth of the spinach in the greenhouse must be ventilated from the greenhouse from time to time, which is conducive to the evaporation of water vapor, thereby ensuring the reasonable humidity required for the growth of the spinach.

6 pest control

In the high-yield cultivation management process of greenhouse rotins in early spring, the most important link is to control the pests and diseases that invade the water spinach. For diseases, the most common ones are stem rot (which causes the rot of the spinach) and squatting (which causes the wind spinach to resist wind and weak pressure). For pests, the most threatening to the spinach is the red spider and the mites. For pests and diseases that endanger the water spinach, pesticides must be sprayed, but it should be noted that the pesticides need to be diluted. After all, the spinach is for human consumption, so the concentration of pesticides for controlling pests and diseases should not be too high. If the pesticide content in the spinach is too high, it will eventually threaten the health and safety of human life. Therefore, the prevention and control of pests and diseases should be implemented in all stages of the growth of water spinach, paying close attention to the growth of spinach.

7 harvesting

Harvesting is the last step in the cultivation of water spinach. Usually, the life cycle of the greenhouse in early spring is about 30 days, and the height of the spinach is usually about 35cm. Because the stem of the spinach is slender and fragile, do not break it from the middle of the stem when harvesting. In addition, the harvesting of the spinach should take into account the nutritional status and the length of the growth cycle, pay attention to the rationality of the time allocation, and resolutely avoid the phenomenon that the longevity causes the rotation of the spinach. When harvesting, it is necessary to formulate a scientific and reasonable plan in advance, and collect it in time and in batches to ensure that the water spinach is more fresh, green and nutritious after high-yield cultivation in the early spring greenhouse.

8 High-yield cultivation suggestions for greenhouse rotins in early spring

In recent years, China has made breakthroughs in the research on high-yield cultivation techniques of greenhouse vegetables in early spring. Based on the theoretical knowledge and practical work experience that I have been learning over the years, the author proposes the following planting suggestions: 1. Promote the high-yield cultivation techniques of early spring greenhouse vegetables to promote people's deep understanding of this technology, which is conducive to the development of other new technologies; Continue to increase the optimization and upgrading of pollution-free vegetable technology, and gradually cultivate more varieties, higher nutritional value, healthier and safer vegetables; 3 because the health and safety of vegetables is directly related to people's life and health, so we must strictly monitor vegetables. The growth process uses advanced and scientific techniques to grow excellent vegetable varieties. 4 Establish a high-yield cultivation base for early-season greenhouse vegetables of appropriate scale. Regularly organize primary and secondary school students and local residents to visit these high-yield cultivation bases for early spring greenhouses and deepen the green The understanding of vegetables and the promotion of sustainable economic development are conducive to the construction of ecological civilization.

9 Conclusion

In the current era, the innovative development of science and technology has made high-yield cultivation techniques for greenhouse vegetables in early spring.
