Exploring the method of integrated cultivation of cucumber water and fertilizer
The cultivation technology of water and fertilizer integration is now common in many areas of China. Some farmers have mastered the integrated cultivation technology of water and fertilizer. The following is mainly to bring about the integrated cultivation method of cucumber water and fertilizer. Variety selection The integrated cultivation method of water and fertilizer has certain requirements for cucumber varieties in application. Therefore, in the application of integrated water and fertilizer cultivation methods, it is necessary to select suitable cucumber varieties first, and it is required to have certain characteristics of disease resistance, drought resistance and high yield. In order to maximize the efficiency of integrated water and fertilizer cultivation. 2. Seeding and seedling 2.1 sowing In the cultivation, it is necessary to select the most suitable cucumber sowing time for sowing. Generally, the cucumber is planted in the period from January to March or June to August. Before sowing, the seeds should be soaked and germinated, but the specific sowing time is required. According to the actual weather conditions in the local area, it is generally required to reach an average temperature of 18 degrees Celsius or more to ensure that the seeds can germinate and grow normally. The method of soaking and germination is to soak the seeds with 0.1% potassium permanganate solution for 10 min, rinse with water for 3~4 times, then soak for 4~5 h with warm water of about 25 °C, drain and wrap it in a damp cloth at 25~30 °C. In the environment, germination; when 60% to 70% of the seeds are exposed, the germination ends. 2.2 nursery Cucumber should be made into a nursery bed before breeding. It needs to be made into a high ridge, 10-15 cm high and 40 cm wide. The middle and low sides of the ridge are high. Then, when raising seedlings, it is necessary to use a variety of materials to make a nursery bed. Mixing and mixing some of the fermented organic fertilizer, diammonium phosphate and urea to ensure that the seedling bed can provide sufficient growth nutrients for the cucumber seedlings and promote the growth and development of the seedlings. 3. Water and fertilizer work Before the customization of cucumber seedlings, the land should be managed to provide sufficient water and fertilizer conditions for the growth of seedlings. In the irrigation aspect, try to use the drip irrigation system, pump water from the water source, add some fertilizer suitable for the growth of cucumber seedlings in the water, and transport it together with water to the seedlings, so that the fertilizer can be directly applied during the pumping and pressurization. The water and fertilizer are sent to the main pipe to be evenly transported to the root soil of the seedling at the dripper. This process can greatly reduce the waste of water and fertilizer, and the way of drip irrigation can also effectively improve the efficiency and effectiveness of irrigation, which is very beneficial for the growth of cucumber seedlings. Through drip irrigation, the water pressure can also be adjusted to allow water to be poured into the root soil of the crop in a point-wise manner to improve irrigation quality. 4. Colonization After the cucumber seedlings are cultivated to a certain stage, they can be colonized. The selection of the general planting date is determined according to the average temperature. For cucumbers, it is necessary to ensure that the surrounding average temperature reaches 18 °C. Colonization, try to choose sunny days when planting, pay attention to the plant spacing between seedlings during planting, control the density of seedlings, and prevent obstruction after late growth. The indoor temperature of 5~10cm deep soil is stable above 10°C, the row spacing is about 100cm, the plant spacing is 20~25cm, and the planting density is 3000~4000/667m2. 5. Management after colonization 5.1 top dressing Cucumber seedlings should be topdressed several times after successful customization. Cucumber needs attention when topdressing, right, the reasonable ratio of NPK, the scientific ratio is 1.2:1:1.5, strictly follow the scientific proportion in topdressing , supplemented by three major elements, which is very beneficial for the growth of cucumber seedlings. In the top dressing, it is also necessary to supplement the different elements according to the various growth stages of the cucumber seedlings. Generally, in the early stage of planting, the demand for nitrogen is large, and in the growing season, the demand for phosphorus is relatively large, while the potassium is cucumber. The elements that are always needed during the growth process. 5.2 Temperature Management After cucumber planting, temperature management is needed, because the average temperature of cucumber is not high, and the weather conditions are easy to repeat. Therefore, it is necessary to protect the cucumber seedlings from cold and heat, and the temperature and humidity have a great influence on the pests and diseases of cucumber. Therefore, in the daily management work, in addition to doing the insulation work of cucumber seedlings, it is necessary to strengthen the illumination of the seedlings, increase the illumination time, and do a good job of ventilation. 5.3 Plant adjustment The adjustment of the plant is mainly to observe the cucumber plants, adjust the plants according to their different growth cycles, and timely carry out the truss, tie vines and pruning forks to prevent the cucumber plants from lodging, in the process of their growth. The yellow leaves and old leaves should be removed in time. 6 pest control In the cultivation process of cucumber, the prevention and control of pests and diseases is very important. It is of great significance for the healthy growth of cucumber plants. Therefore, after planting, the cucumber plants need to do the relevant pest control work. When planting, choose to grow. The age-appropriate seedlings with good condition are carefully cultivated; in addition, the relevant pest control agents should be prepared, and timely treatment should be carried out in the event of pests and diseases. In modern agricultural production, the integrated cultivation method of water and fertilizer has a significant impact on the growth and yield of crops. In the process of planting cucumbers, the integrated cultivation method of water and fertilizer has great advantages, so in modern agricultural production, Cucumber can be integrated with water and fertilizer when planting. It can prevent some medicine or blood from splashing on the face, thus protecting the eyes. This kind of glasses is generally used in conjunction with masks and surgical caps to fully protect the doctor's head.
4. The breathability must be good, generally there are vents

1. Prevent blood, potion and other liquids that cause damage to the skin from causing unpredictable damage to the eyes.
2. It can prevent the impact of objects on the eyes during close surgery.
3. The inner space of the eye mask is large enough for doctors who wear myopia glasses.
