The most High-yielding cultivation techniques of New Zealand Flowers

Broccoli is also called broccoli, tender cauliflower, broccoli, with its tender flowers, buds composed of emerald green flower ball for food, not only tender, delicious, nutritious, and adaptable, easy to cultivate, is a very promising nutritional health care high-grade vegetables.

culture season

Green cauliflower can be cultivated in spring and autumn. Spring planting is more than sunny bed seedling in mid-late January, seedling period is 50 to 60 days, open field planting in mid-late March, harvest in mid-late May; autumn planting is sown in mid-July, open field planting in mid-August, harvest in mid-late October.

Soil preparation, fertilization and planting

Green cauliflower growth potential is strong, need fertilizer quantity is big, must combine soil preparation to apply sufficient base fertilizer.

General mu of high-quality fertilizer 5000 kg, decomposed manure 500 to 1000 kg, calcium superphosphate 30 to 40 kg, plant ash 50 kg. After base fertilizer application, deep ploughing and fine harrowing are carried out, followed by leveling to form flat beds 1.3 to 1.5 m wide. When the green cauliflower seedlings grow to 5 to 6 true leaves, they are generally planted in 2 rows per plot, the plant spacing is 30 to 40 cm, and the planting density is about 2500 plants per mu.

Early-maturing varieties can be properly planted, with about 3000 plants per mu is appropriate.

fertilizer and water management

Green cauliflower is fond of fertilizer and water, and the key to high quality and high yield is to apply fertilizer and water in due time by stages. Nitrogen fertilizer is the main type of topdressing, and phosphorus and potassium fertilizer should be applied appropriately to promote the rapid growth of flower bulb when entering the flower bulb formation period; the top flower bulb and side flower bulb of green cauliflower should be harvested for many times, and topdressing should be applied in time after each harvest to promote the growth of side flower bulb. Green cauliflower needs a large amount of water, in the rosette period and flower ball formation period to timely watering, keep the soil moist; rainy areas or seasons, timely drainage, prevent ponding retting roots.

recovery

Green cauliflower in the top of the plant bulb fully expanded, bud has not yet opened when the harvest is good; harvest too late easy to cause loose bulb and flowering. Harvest time, the lower part of the bulb with flower stems about 10 cm cut off together. After the top flower bulb is harvested, the axillary bud of the plant germinates and quickly grows lateral branches, and the top of the stem lateral branches forms a flower bulb, namely a lateral flower bulb; when the lateral flower bulb grows to a certain size and the flower bud has not yet opened, it can be harvested again. In this way, it is generally possible to harvest 2 to 3 times in succession.
