Is planting cucumber a simple insert, tied vine, pruning and tipping? No, let's learn about the cultivation techniques of cucumber together with Huinong.com.
Variety selection
First of all, cucumber varieties should choose high-quality varieties with high disease resistance and high yield. For example, Zhongnongda No. 11, Bomei 4, Zhongnong 12, etc.
2. Nursery
The seedling age is about 35 days. The seedlings are standard: the cotyledons are intact, there are 3-5 true leaves, the internodes are shorter, the petiole and the main vine are at an angle of 45 degrees, the leaves are dark green, the leaves are thick, the stems are thick, and the roots are developed. , no pests and diseases.
3. Fertilize and do 畦
Soil preparation, fertilization of decomposed organic fertilizer 5 cubic meters, 25-30 kg of superphosphate or 10-15 kg of diammonium phosphate. Tillage tillage before planting, 畦 wide 1.2 m, height 15 cm or more, and covered with plastic film.
4. Colonization
4.1 Determination of the planting period
Colonization is carried out as soon as possible after ensuring that it is not frozen after planting. Chengde is generally planted at the end of April and early May. Temperature index requirements: the lowest night temperature is higher than 5 °C, and the soil temperature is higher than 12 °C at 0-10 cm. The autumn dew cucumber is delivered by live broadcast.
4.2 Planting density
4000-4500 plants/mu, the size is fixed, the small row spacing is 40 cm, the large row spacing is 80 cm, the plant spacing is 25-30 cm, and it is legally planted with dark water.
5. Insert
After planting, insert the rack early, windproof seedlings, insert frame can use flower stand or herringbone frame, about 8-10 cm from the root.
6. Tied up

In the morning, the stems and vines are easy to break. The tightness of the tied vines should be weak and weak, and the plants with strong growth potential should be tightly tied tightly and the growth points should be consistent.
7. Pruning and tipping
The main vine should be removed from all the side branches, and the side vines should leave one or two leaf tips behind the squash and knock off all the tendrils. When the stem exceeds the head of the rack, it is necessary to promptly pick up the tip to promote the growth of the lower melon. It is also possible to suppress the growth of the upper part by twisting the tip.
8. Fertilizer management
Timely watering and cultivating, the amount and frequency of water depends on the weather and growth period. The slow seedling water is poured 5 to 7 days after planting; the water is controlled before the melon, the cultivating, the seedling; the root melon is 10~12cm long when the melon water is poured; the result is watered every 5-7 days. The principle of top dressing is that the front is light and heavy, and a small amount is repeated. The melon fertilizer is applied after the root melon is sitting, and the melon fertilizer is harvested after the root melon is harvested. Advocate the use of organic fertilizer for topdressing.
The above is the cultivation method of cucumber, I hope to help farmers friends, what kind of knowledge do you want to know about cucumber cultivation, pest control, water and fertilizer management, etc.
