1. Variety selection should choose high yield, strong disease resistance, good commercial quality, suitable for spring cultivated varieties, Jinchun No. 4 and Jinlu No. 4; suitable varieties for cultivation in autumn, there are Jinchun No. 4 and Jinyou. No. 4, Tangshan autumn melon and so on.
2. The seedling age is about 35 days. The seedling standard: the cotyledon is intact, there are 3-5 true leaves, the internodes are shorter, the angle between the petiole and the main vine is 45 degrees, the leaves are dark green, the leaves are thick, and the stems are strong. The root system is developed without pests and diseases.
3, fertilization to do soil preparation, fertilization of organic fertilizer 5 cubic meters, 25-30 kg of superphosphate or 10-15 kg of diammonium phosphate. Before planting, plow tillage, hoe width 1.2 meters, height 15 cm or more, and mulching.
4. Colonization (1) The determination of the colonization period is to ensure colonization as soon as possible after the planting is ensured, and Chengde District is generally planted at the end of April and early May. Temperature requirements: Minimum night temperature above 5°C, soil temperature above 0°C at 12°C. The cucumber in the autumn dew adopts the live broadcast method.
(2) Density of colonization
4000-4500 strains/acre, planted in small and large rows, 40 cm apart, 80 cm wide spacing, 25-30 cm spacing, legally planted in dark water.
(3) Field Management
A. Insert the rack early after the planting, windproof pumping seedlings, plug racks can use flower stand or herringbone frame, about 8-10 cm from the root.
B, tied vines using "8" method tied vines, prevention of abrasions stems and vine sag. Every 2-3 knots should be tied once in the afternoon. In the morning, the stems and branches are easy to break. The tightness of the bound vines should be strong and weak. The plants with strong growth potential should be tied tightly and the growth points should be the same.
C, pruning and pods should be removed from all the side branches, side vines leave one to two tips after the melon, and remove all the tendrils. When the stem exceeds the head, it must be tipped promptly to promote the growth of the lower part of the melon, and it can also be used to suppress the growth of the upper part by twisting the tip.
D, fertilizer and water management timely watering and cultivator, the amount of water and the number of times and depending on the weather, growth period may be. Seedlings of water are poured 5 to 7 days after planting; water, cultivator, and seedlings are planted before sitting on the melons; watering of the melons is performed when the roots are 10 to 12cm long; watering is poured every 5 to 7 days. The principle of top-dressing is to lightly weigh and lightly weight, and a small number of times, so that the melon fertilizer will be applied after the root melon sat, and the melon fertilizer will be taken after the root melon is harvested. Promote the use of organic fertilizer topdressing.
