(I) Characteristics Green broccoli is the main ball-type hybrid, and its growth potential is particularly strong and its heat resistance is strong. Planting at temperatures above 30°C can still harvest compact flower bulbs. In the summer and autumn, the whole growth period is 80 days. The plant height is 65 cm and the development degree is about 55 cm. It is suitable for dense planting. The number of outer leaves is 16-17 pieces. The leaves are light green in colour with silty leaves and lanceolate leaves. The main ball is nearly hemispherical, with a diameter of about 13 centimeters and a tight ball with a weight of 280 grams. The buds are coarse and neat, the balls are green, suitable for cultivation in the summer and autumn, and exported fresh. Flower bulbs grow faster and colonize until harvesting for about 50 days. More resistant to root rot, downy mildew.
(b) Cultivation points
1. Broadcasting whole seedlings and cultivating young seedlings Green broccoli is mainly cultivated in the Yangtze River basin in summer and autumn, and generally sowed in mid-late July. At this time, it is at high temperatures and rain, the seedlings are extremely prolonged, and there are many insect pests, and all seedlings are cultivated. Strong seedlings are the key to ensuring successful cultivation.
(1)Nutrition block nursery: Select the plots with loose soil and the former to be non-cruciferous crops for the seedbed, 15 acres of field seedbed with about 400 square meters, apply 500 kg of decomposed organic fertilizer before planting Mix the phoxim with the soil, build a 1.2-meter-wide, 20-cm-high file after making fine, and after making water, make a nutrient block with a diameter of 6-8 cm, and then apply it to the bottom water. One seed was sown in the block and then covered with 1 cm of sieved fine soil.
(2) Cooling and protecting the seedlings to promote seedling emergence: Immediately after sowing, cover one layer of plastic film to protect the soil, otherwise it is not easy to emerge. After the film is covered with straw curtain or 90% of the shade net cooling (grass curtain effect is better than the shade net), the temperature is controlled at about 25 °C to promote emergence. After 2-3 days sowing, the seedlings were checked. When 80% of the seedlings emerged, the mulch and shading were removed in the evening. At the same time, a 80 cm high shady shed was placed on the seedling bed. The shading net was cooled from 10 am to 3 pm. Days are not covered. Cover the membranes to shelter from the rain before the storm.
(3) Seed management: Broccoli does not water before breaking the heart to prevent high hypocotyls from forming high-legged seedlings; when the topsoil of the nursery bed becomes white, it is poured with water once. Generally, it will not be poured or poured, but will be poured thoroughly. Seedling watering 2-3 times, can be applied topdressing thin human waste. Weeds should be removed manually in time. The seedling period should not exceed 30 days, otherwise it will affect the size of the flower ball.
2. Apply base fertilizer and reasonably close planting. Choose sandy loam with good drainage and irrigation conditions as the planting field. Before planting, 2000-3000 kg of organic fertilizer is applied per mu, 30 kg of high-concentration compound fertilizer, and 1 kg of boron fertilizer (without the application of boron, the bulbs are easy to be hollow, and 10-12 leaves may also be used for spraying.) . Then cultivating and turning hoeing, using high ridge double row, 1 meter 1 combination, plant spacing 40 centimeters, planting 3333 acres. Immediately after planting, root water was poured to shorten the seedling period.
3. Field management (1) Fertilizer management: In the premise of applying basic fertilizer, 3 times of top dressing is applied, that is, 1 to 10 days after planting to recover 1 seedling, Mushi 5 kg of urea and 100% of thin and decomposed human excreta. 10-12 leaves when Shifafei, Mushi urea 15 kg, high-concentration compound fertilizer 10 kg; flower buds have the size of table tennis, chase after the application of fertilizer, Mushi urea 5 kg.
(2) Moisture management: Moisture management shall be conducted in a timely manner according to soil moisture in the field. In summer and autumn, high temperature irrigation should be carried out when the water is cool and cool, and horse water is generally irrigated after the evening. In the second day, water should not be left in the fields. After the rain, pay attention to timely drainage and cultivator, soil, in order to increase the permeability of the soil and promote root development.
(3) Prevention of pests and diseases: Diseases should be prevented mainly. In addition to strengthening water management, the lower diseased leaves should be stripped at the late growth stage to improve the ventilation and light transmission conditions. After 15 days of colonization, downy mildew can be controlled with 72.2% of Propazine 600 times, or 75% of chlorothalonil 500 times, or 40% diethylaluminophosphate 200 times every 10-15 days; 72% of available agricultural use Streptomycin 3000 times, or 77% can kill WP 1500 times and other agents used alternately 2-3 times to prevent root rot. The pests mainly include cabbage caterpillar, diamondback moth, aphid, etc., which can be used to control Pieris rapae, Plutella xylostella at 2.5% vegetable hi 1000 times, or 5% fipronil 1500 times, or 0.3% matrine 3000 times; 2% imidacloprid 2000 times, or 50% anti-influx 2000-3000 times and other control aphids.
4. When harvesting and maintaining the flowers, the ball should be harvested in batches in time, and one harvest should be matured. Generally, harvesting ends before and after 9am. When harvesting, it shall be cut along with the tender stems with a length of about 15 centimeters under the ball, and retain the 2-3 leaflets around the flower ball, remove the remaining leaves, and put it into a special box for transportation and sales. When packing, it must be discharged neatly and cannot be squeezed. Avoid collecting too long after harvest to prevent flower yellowing and water loss. After the harvest, the product is slightly trimmed, immediately pre-cooled (soaked in cold water at 0°C), stored in a low-temperature, high-humidity environment at 0°C and relative humidity of 95%-100%, and it can be stored for 8-10 days.
