Greenhouse cucumber management after planting

In order to grow good vegetables and fruits, high-quality management is very important. Now that most of the overwintering and picking cucumbers have been planted for a period of time, the cultivation of strong trees is the key point of management. What are the management measures after the cultivation of greenhouse cucumbers? ?

Robust plants are the guarantee of high yields of vegetables, especially for overwintering glutinous vegetables growing during the low-temperature and high-humidity season, and Zhuangshu is also a guarantee for enhancing plant resistance to cold and disease, and increasing yield and income. What are the problems that farmers should pay attention to in management?

First, temperature management

1. Colonization to the sowing period: The facilities are basically not ventilated for about 3 days after colonization, and are maintained at 25 to 28°C during the day and 15°C at night.

2. Rehabilitate seedlings to harvesting: After easing seedlings, it is advisable to use no more than 25°C during sunny daytime and 10-12°C during the night; about 20°C during cloudy daytime and 8～10°C during nighttime. Try to keep the temperature difference between day and night at 8°C. the above. The weather should be removed in time on sunny days and covered in the afternoon when the indoor temperature drops to 18-20°C. If the room temperature exceeds 30°C, ventilate immediately. If the room continuously falls below 5°C, auxiliary heating measures should be taken.

3. Harvesting period: After entering the harvesting period, keeping the daytime temperature no lower than 20°C, the cucumber fruit grows fastest when it is 25～30°C.

Second, fertilizer management

1. Planting to harvest: After planting, topdressing 1 to 2 times depending on the plant growth. The first time can be applied 7 to 10 days after planting, and apply 4 to 5 kg of urea per 667 square meters for the second time. In the ranch to flowering, apply urea 5 to 10 kilograms per 667 square meters to promote flowering results.

2. Harvesting period: After entering the harvesting period, the fertilizer and water should master the principles of light pouring and ground pouring. The amount of fertilizer should be light and heavy. Depending on the plant growth and harvest conditions, it is gradually increased from 5 kg of ternary compound fertilizer to 5 kg per 667 m2. It is recommended to use the golden babe microbial fertilizer (increased yield, increased fertility, enhanced stress resistance, early maturing and high yield, cost reduction and efficiency increase)

Third, water management

Cucumbers require large amounts of water but are impatient. The water requirement at the seedling stage is small. At this time, the soil moisture is too high and it easily causes rot. After entering the fruiting period, the water requirement is large. If the water supply or water supply is not sufficient in time, it will seriously affect the fruit growth and impair the ability of the results. Therefore, we must maintain soil moisture in the field management, timely irrigation when drought, you can use irrigation, drip irrigation, furrow irrigation, etc., to avoid emergency irrigation, irrigation and flood irrigation, furrow irrigation should promptly remove the trench water, so as not to cause rot.

Fourth, other measures

1. Frame, tie the vines, go to the side branches, pick up the heart and put it in time after the cucumbers are pumped. Take the “person” type frame or parallel frame, and you can also use the rope to pull; The vines were planted at a height of 30-35 cm, and each vine was tied once every 3 to 4 knots. Tying vines is usually done in the afternoon to avoid breaking vines. When the main frame is full, it will be picked up in time to prompt the vines and look back. The side branches were removed in time, and all the side branches below 10 nodes were removed. Others could leave 2 leaves topping.

2. Weeding: Weeding field weeds 1 times before weaving, then weeding 1 or 2 times depending on weed growth to ensure that there is no weed damage in the field.

3, removal of diseased leaves, disease melon: Into the harvest period after the timely removal of diseased melons, malformed melons, late growth should also promptly remove the following diseased leaves, increase ventilation and light.
