Master orchid seedling technology, broccoli fertilization technology

Broccoli is a kind of vegetable that many friends like, and proper fertilization is needed in the process of growing broccoli, so how is broccoli fertilized? Next, I would like to introduce the fertilization technology of broccoli.

How to fertilize broccoli

Ploughing, weeding and soil cultivation. The slow seedling of broccoli was planted for the first time, which was removed deeply from the seedling and shallowly removed near the seedling to prevent root damage, while cultivating soil at the base of the seedling to prevent seedling inversion. In the future, combined with topdressing and watering, and then ploughing and cultivating the soil twice, but it is necessary to ensure that the roots will not be hurt.

Broccoli under fertilizer and water management is a vegetable that needs more fertilizer, especially the top flower, side flower and mid-late ripening varieties. during the growth period, many times of topdressing is needed to make the plant grow healthily and obtain higher flower head yield. generally slow seedling for 10-15 days, topdressing the first fertilizer, urea 10 kg per mu, diammonium phosphate 15 kg, potassium sulfate 7.5 kg per mu Spraying 0.05% Mel 0.1% borax solution and 0.05% Mel 0.1% ammonium molybdate solution on leaves during the bulb expansion period can improve the quality of flower buds and reduce the occurrence of yellow buds and coke buds. Thin fertilizer can be applied once after the top flower head is harvested to increase the yield of the lateral flower head and prolong the harvest period. However, excessive application of nitrogen fertilizer should not be applied in the late growth stage to avoid decay.

Fertilization techniques of broccoli

Broccoli likes to be moist and not resistant to drought, and needs more water in the whole growth process. In case of autumn drought, broccoli should be watered every 5-7 days after planting to ensure that the soil is often in a moist state, and should be watered in time after each topdressing, so that the roots can absorb nutrients. Broccoli like wet and afraid of waterlogging, watering avoid flooding, in case of heavy rain should be timely exclusion of stagnant water in the field, after the rosette period, appropriate control of watering to prevent plant overgrowth. After forming a small flower ball, water it in time after the diameter of the flower ball reaches 2-3 cm to promote rapid expansion. To remove the special species of lateral branch and apical corm, lateral buds should be removed before harvest, and there are more lateral branches. Generally, only 4-5 strong lateral branches are left, and thin and weak lateral branches are erased, which can reduce nutrient consumption. When the average temperature of the day is below 10 ℃, in order to concentrate nutrients for the main corm, lateral branches should also be wiped off as soon as possible.

The above is the introduction of broccoli fertilization technology, broccoli planting friends, according to the actual planting situation, reference to the above fertilization technology, reasonable fertilization.
