Shed cucumber in spring, because of high yield, good efficiency, large planting area. However, in production, due to the large growth of cucumber plants, often caused by early seedlings, seedlings idling idle land, late planting leaves flourishing, so that the air ventilation and poor light, resulting in plant growth, premature aging, resulting in a large number of melon and reduce production. In order to solve this problem, the author adopted a high, dense, thin, and falling cultivation method and solved this problem better. The specific cultivation techniques are described as follows: 1. Gaochun Site Preparation. Take sorghum coated land preparation measures. Before the site preparation, 5 tons of high-quality farmyard fertilizer per acre, 15-20 kg of diammonium and 100 kg of potassium carbonate were used for 130 cm. The width of the surface was 80 cm. The width of the ravine was 50 cm. The width was 25 cm. The height was high. 25-30 centimeters, a ditch with an upper width of 30 centimeters, a width of 15 centimeters, and a depth of 8-15 centimeters shall be provided on the raft. The raft shall be covered with a plastic film to increase the temperature, cool the temperature, and protect the raft. 2, rational close planting. In the sorghum covered with plastic film, the dark irrigation ditch is planted at a spacing of 15-20 cm on both sides, and 5000-6700 strains of mu will be planted. This is a key technical measure to increase early production and increase total production. 3, thin seedlings and sparse planting. (1) introduction of vines on the shelves: can be used to hang the vine on the tear film, tear the upper end of the film out of 30-50 cm, in preparation for later use. The method of putting on the shelves is to keep two strains of one strain on the shelf and one strain on the other. (2) Tossing and sparse seedlings; for those not standing on the shelves, when they have 10-12 leaves, they will pick their hearts and promote their fruiting. This strain can produce 4-5 melons, all of which are early yields, can increase early production by more than 50%, and pick melons after picking. When the last plant grows to a height of 120-150 cm, according to the market conditions, one of them will be picked up and promoted to go on the market, stabilizing the mid-term yield, and pulling the pods after the melons are harvested. After two times of sparse seedlings, the spacing of the reserved plants can reach 45-60 cm, which enhances the ventilation and light transmission capacity of the field, and inhibits the occurrence of pests and diseases. 4, falling vine management. During the middle and late stages of cucumber growth, the lower leaves of the plants were yellowed and lost their photosynthetic capacity due to a variety of factors such as pests and insects. Plant upper ceiling. In order to allow the plants to continue growing the melons, the vines are dropped, that is, the plants are allowed to fall as a whole. The upper part of the plants has an extension space to continue to grow the melons, and the lower part of the melons is pressed around the roots. When falling, the plants maintain 12-15 functional leaves, and at the same time keep the vine from the shed membrane about 40 cm. This method can effectively prolong the growth period of cucumber, and the total yield of cucumber can be increased by more than 30%. 5, water and fertilizer management. Irrigation and fertilization were performed in the subcavernal irrigated ditch. This method can effectively reduce the air humidity in the shed and inhibit the occurrence of diseases. Top dressing consists of decomposing thin manure or thin cakes with fertilizer, combined with chemical fertilizers, combined with watering, and applied with water. Other management, such as nursery, pruning, pest control, etc., are the same as conventional cultivation. Pest control adheres to the principles of biological control, physical control, and chemical control. Pharmaceutics control dust method instead of spray method, do ground observation, early detection, early medication, timely prevention and treatment.
