The seed price and planting method of the most New Zealand flower

Broccoli, also known as broccoli, etc., is a cruciferous brassica-biennial herb, originating from the eastern Mediterranean coast, introduced into China at the end of the 19th century, first planted in Taiwan Province, then cultivated in Guangdong, Fujian, Yunnan, Beijing, Shanghai and other places, now widely cultivated in the north and south of China, let's take a look at broccoli seed prices and planting methods!

How much is a gram of broccoli seeds?

The price of broccoli seeds is about 12~20 yuan a gram, but the price varies greatly due to the quality, variety, origin and market of seeds. In the production of broccoli, we should select varieties with strong plant growth potential, dark green flower buds, few scorched buds, round flower bulbs, few lateral buds, small buds, large flower bulbs, disease resistance, heat resistance, cold resistance and wide adaptability, such as excellent, dragon green, landscape, jade crown, oriental green treasure, Wanlu, green show and other varieties, but they must meet the national secondary seed standard before they can be used.

What kinds of broccoli are there?

1. Excellent: early maturity variety, mushroom shaped top prominent, dark green color, single ball weight 350~400 grams, tight flower ball, fine flower bud, good commodity, less lateral branches, suitable for early spring and autumn cultivation.

2. Future: Early maturity variety, erect variety suitable for dense planting, mushroom shaped flower ball, dark green color, full shape, good commodity quality, suitable for autumn cultivation.

3. Landscape: medium-mature variety, vigorous growth, large development degree, single ball weight of about 500 grams, semicircular, tight flower ball, fine bud, blue-green, poor cold resistance, but strong resistance.

4. Green belt: medium-mature variety, single ball weight about 500 grams, vigorous growth, good quality, semicircular shape, both main and side flower balls, easy to hollow when fertilizer and water are abundant, high temperature and rainy, easy to appear pansky, frost and purple.

5. Holy Green: Mid-late maturing variety, vigorous growth, cold tolerance, single ball weight of about 500 grams, semicircular, fine bud, thick green, not easy to hollow.

Growing conditions for broccoli

1, light: broccoli likes sufficient light, light enough when the plant grows strong, can form a strong vegetative body, conducive to photosynthesis and nutrient accumulation, so that the ball compact dense, bright green color quality is good, but the summer sun is too strong is not conducive to growth and development.

2, temperature: broccoli has a strong cold and heat resistance, in the range of 5~20℃, the higher the temperature, the faster the growth and development, germination temperature 20~25℃, seedling stage temperature 15~20℃, rosette stage temperature 20~22℃, bulb development temperature 15~18℃.

3, water: broccoli growth process in the water demand is large, especially the vigorous growth of leaves and flower bulb formation period can not be water shortage, but the seedling rainy or high soil moisture is easy to cause black rot, black spot disease, etc., flower bulb formation period soil moisture field water capacity 70~80%.

4. Soil: Broccoli is suitable for planting on loam and sandy loam with good irrigation, deep tillage layer, loose and fertile soil and strong water and soil conservation fertility. PH range is 5.5~8, with 6 as the best. The ratio of N, P and K in the whole growth process is 14:5:8.

How to sow broccoli

1. Sowing time: The sowing time of broccoli double mulching cultivation in autumn is early July, winter cultivation in solar greenhouse is from late July to August, early spring cultivation in solar greenhouse is from early September to early October, early spring cultivation in plastic greenhouse and small arch shed is November, and spring plastic film cultivation is January.

2, soaking treatment: broccoli seeds with 33℃ warm water soaking for 15 minutes and keep stirring, until the water temperature drops to 20℃ stop, continue to soak with warm water for 4 hours, wash clean with water after germination.

3, seed germination: broccoli soaked seeds wrapped with wet cotton gauze, at 30℃ temperature for germination. Wash with clean water once a day and sow when 60% of seeds are white.

4, seedbed selection: broccoli seedling is short, seedbed selection in the terrain, convenient irrigation, soil rich in organic matter, two years did not plant cruciferous vegetables or rice before the field, seedbed direction to the north and south is appropriate.

5. Apply enough basal fertilizer: deep ploughing 15~20 days before broccoli sowing, applying ternary compound fertilizer 15 kg plus calcium superphosphate 5 kg or pouring 2500 kg decomposed human excrement in the first 7~10 days, digging and raking the ground, making a seeding bed about 1.2 meters wide, and the seedling field ratio is 1:20~30.

6. Mixing and sowing: Before sowing broccoli, irrigate the seedbed once with permeable water and apply 1000 times phoxim and other chemicals. When sowing, mix the seeds with appropriate amount of sand and spread them evenly in the seedbed. After sowing, use a shovel to suppress them, and then sprinkle a layer of medicinal soil mixed with 0.1% carbendazim and dexone.

7. Sunshade and heat preservation: after broccoli is sown in summer, a layer of sunshade net is laid on the seedbed, a small arch shed is set up, and then a layer of sunshade net is covered to carry out double-layer sunshade, moisture preservation and cooling seedling raising. In winter and spring, a layer of plastic film and a layer of shed film are used to carry out double-film covering and heat preservation seedling raising.

How to grow broccoli

1. Soil preparation and fertilization: The root system of broccoli is relatively shallow, so it is required to be planted in fertile soil, water and fertilizer conservation plot. Generally, 100kg organic fertilizer, 10kg urea, 25kg compound fertilizer and 2kg borax are used as base fertilizer per mu, and the cultivated land is raked and ditched for fertilization.

2. Reasonable planting: When the broccoli seedlings grow to 6 leaves and one heart, the temperature of the soil layer of 10 cm should be stabilized above 10℃, and the seedling age can be transplanted for 30~35 days. The transplanted seedlings should be sealed or sealed in the soil without exceeding the cotyledon mark, and the growth point should not be buried. After transplanting, water should be poured thoroughly.

3. Cultivation management: check and replenish seedlings in time within 2 days after broccoli transplanting, give sufficient nutrients and water, loosen soil more, keep the lower soil moist, cultivate properly, eradicate weeds, generally cultivate once, deeply loosen and topdressing once, and remove artificial weeds twice.

4. Topdressing method: 5 kg urea and 10 kg potassium sulfate per mu in 7~10 days after broccoli planting, 25 kg compound fertilizer and 10 kg potassium sulfate per mu in 15~20 days, potassium dihydrogen phosphate, boron treasure or 0.05~0.10% borax and ammonium molybdate solution shall be sprayed once at the initial stage of flower bulb formation.

5, irrigation methods: broccoli needs a little more water than other crops, in addition to the seedling stage should be properly controlled soil moisture, other growth and development stages should ensure sufficient water, generally with artificial furrow irrigation or mechanical sprinkler irrigation, it is best to use advanced sprinkler irrigation equipment.

6. Remove the lateral branches: Broccoli top bulb is a special variety, so the lateral branches should be removed before the flower bulb appears. The lateral branches of the top and lateral flower bulb dual-purpose varieties are more, and 1~2 healthy lateral branches are generally left at the upper part to remove the rest, so as to reduce nutrient consumption.

7. Temperature management: The normal temperature of broccoli at the beginning of flower bulb formation is about 25℃, and the high temperature of 30℃ in the field cannot exceed three consecutive days. Temperature control measures should be taken for more than three days. Artificial leaf covering or covering, artificial rainfall and other methods can be used.

8, pest control: broccoli is prone to a variety of diseases and insect pests, after transplantation should be timely investigated to prevent the occurrence of diseases and insect pests, spray internal suction agent as a preventive agent, fumigation, contact kill as a prevention agent, to use green, pollution-free pesticides for prevention and control.
