Broccoli Double Ball Cultivation Technique

First, the choice of species. Has been successful in the excellent, green male 90 and other varieties.

Second, sowing in advance. Because picking up will cause a growth pause, the harvest period may be postponed by 8-10 days. This will require sowing about 6 days in advance to harvest at the same time.

Third, topping method. In order not to affect the growth, the first three days before picking, apply a thin fertilizer and apply 45% compound fertilizer 0.5 kg per acre seedbed.

At the seedling stage, 4 true leaves were picked and two true leaves were left. Two lateral shoots were planted in each seedling, and two flower balls could be formed per plant after transplantation. Tossing should be carried out on a sunny day to prevent infection; according to the size of the seedlings, the topping should be carried out in batches. Other nursery management techniques are the same as conventional ones.

Fourth, in addition to Meng. In order to ensure the development of double balls, the buds before the mid growth period must be removed in time. The seedbeds were degerminated one time before colonization, and degerminated on the 15th and 30th days after colonization.

Fifth, the density of colonization. According to experiments, under double-ball processing conditions, as the density increases, the single ball weight drops sharply, the flower ball diameter also becomes smaller, and the flower ball thickness becomes thinner. At a density of 2200, the single ball becomes very small. Basically lost the commodity.

The double-ball cultivation density is suitable for planting 1800-2000 plants per acre.

Six, fertilizer and water management. Under the double-ball treatment conditions, it is necessary to increase the amount of fertilization by about 20% compared with ordinary cultivation, which can ensure good growth and development. Other fertilizer management is the same as conventional.

Seven, increase production effect. Generally, the double ball rate can reach more than 90%, and 700-900 flower balls are added per acre, with a growth rate of about 80%. At the same time, the flower ball has a better color and a round shape, which is suitable for fresh export.

Eight, application prospects. Double-ball cultivation adds a certain amount of labor cost to the topping and de-emergence, and increases the amount of fertilization, but it can save a certain amount of seeds. The total cost of producing the field per acre is about 50 yuan, but it can increase the economic efficiency by more than 600 yuan, and the input-output ratio can reach 1:12, which has very significant economic significance.

Garlic depressed-globose or short conical, with gray or light brown membranous scales skin outside, there were 6 ~ 10 cloves of garlic after peeling leaves, the clove was born around the stem, in a woody stem base discoid, with most of the fibrous root.
