Fertilizing technology of cauliflower

Cauliflower is also known as cauliflower, brassica brassica, suitable for sowing in the warm areas in the south, is one of the specialty vegetables in the south of China.It is suitable for sandy loam or loam which is rich in organic matter and convenient for irrigation and drainage.So what is the principle of applying fertilizer to cauliflower?I would like to share with you the techniques of vegetable manure.
I. principle of applying fertilizer to cauliflower
It is suitable to grow in sandy loam or loam soil which is rich in organic matter and convenient for drainage and irrigation.The absorption of mineral nutrients in cauliflower was the highest, followed by potassium, the lowest phosphate, and the proportion of nitrogen, phosphorus and potassium was 3.5.1?3.4;For each 1000kg of vegetable hearts, it takes 2.2-3.6kg of ammonia (N), 0.6-1.0kg of phosphorus and 1.1-3.8kg of potassium.
For nitrogen absorption of cauliflower plants, seedling period accounted for 22.3%-33.3% of total absorption, leaf growth period for 11.6%-26.8%, and budding to harvest for 39.9%-62%.For potassium absorption, seedling stage accounted for 21.2% to 30.2% of total absorption, leaf growth stage accounted for 19%-25%, and bud to harvest accounted for 44.8% to 59.8%.The total uptake of phosphorus was 17.6%-33.3% in seedling stage, 17.5%-26.4% in leaf growing period, and 42.9%-65% in bud harvesting.
Cauliflower heart in time to complete the furrow, soil deep tillage sunning, foot fertilizer.Generally 1.2-1.5m wide, 20-30cm high, the back of the tortoise.
2. Fertilizing technology of cauliflower
1. Base fertilizer: as a quick growth vegetable with shallow root, short growing period and high planting density, it is necessary to apply base fertilizer.Generally, 80 to 100kg of organic fertilizer (4% of biohumic acid fertilizer or self-fermenting organic fertilizer) was applied on an acre.
2. According to
1) seedling stage: apply hoxin dynamic cream fertilizer rich in fulvic acid (35% high-nitrogen type) and rinse it with water 800 times, every 3 to 5 days, twice in total.
2) growing period of leaves: apply fluxin dynamic cream fertilizer rich in xanthic acid (35% high-nitrogen type) and rinse it once with 300 times of water added.
3) late growth stage: apply fluxin dynamic cream fertilizer rich in xanthic acid (35% high potassium type) and rinse it once with 300 times of water added.
