The broccoli can also be called fist vegetables, Nanchong cuisine, and baby vegetables. The seedlings grow to a certain stage, and the buds growing from the leaf stalks continue to expand, so that they are replaced by swollen buds, each bud 100-200 grams, each The plant has 15-20 buds and is very beautiful. The children's food is rich in various nutrients, the quality is tender, the taste is delicious, stir-fried, fried, fried, simmered, cold-mixed, made into soup, marinated, can be a delicious meal on the banquet table, the following follows the footsteps of Xiaobian Take a look at the vegetable growing techniques.
First, seeding technology
1, choose a variety
The disease resistance, appearance, maturity, yield and quality of different varieties of vegetables are different. Early-maturing varieties include Jizaowa and Zaowa No.1, and mid-late maturity varieties are Duofi No.1. These varieties have a dish shape. The advantages of beauty, high yield and good disease resistance are only the difference between the length of the growth period and the early and late harvest period.
2, seedbed
The seedbed chooses the shady zone, and the soil selects loam or sandy loam with deep soil layer, fertile soil, convenient drainage and irrigation, and no pests and diseases. In August, the soil was turned over, and 15 to 25 kilograms of lime per acre was disinfected to adjust the pH of the soil. At the same time, the manure and manure were added to the manure, and the trace elements such as phosphoric acid cover and plant ash, and boron, magnesium and zinc were added as base fertilizer, and mixed with the seedbed soil. The car is about 1.7 meters wide and spare.
3, sowing
The sowing date is too early, the temperature is too high, and the moss is easy to be cast into a stick shape, forming a high foot; the sowing period is too small or small, and the pineapple shape is not easy to grow into an empty plant, and the yield is low, so according to local planting conditions, Choose the appropriate sowing date.
Second, seedbed seedlings
1, sowing
The germination of colza seeds is suitable for 20 to 28 degrees. Before planting, the fertilized manure is poured to make the surface moist. When sowing, it is ensured to spread evenly. After sowing, it covers 0.5 cm thick fine sand. When 75% of the seedlings are flattened, the straw or shade net is removed in the evening to prevent the seedlings from growing up, and the sunshade nets are used to shelter from the summer.
2, seedlings
During the whole seedling period, the seedlings are 2 to 3 times, and the light manure is applied 2 to 3 times. When the seedlings have 4 true leaves, the soil is removed from the seedbed and planted at a distance of 10 * 15 cm, and the thin manure is poured. Roots, fake plants can be planted after 15 to 20 days to form old and strong seedlings.
3, strong seedlings
The seedlings sowed before September 10 must be replanted by the fake planting seedlings and cultivated strong seedlings, and the late seedlings can be cultivated for 30 days or so.
Third, field management
1, colonization
The sand layer soil or the land block or greenhouse in which the soil layer is deep, sheltered from the wind, sun, water, and irrigation is convenient.
2, soil preparation
20 days before transplanting, the field will be ploughed, 50-80 kg of compound fertilizer and organic fertilizer will be applied per acre before the tillage, and the bottom fertilizer will be turned over 30 cm. After the land is leveled, the box will be opened according to 1.8 m, and the hole will be opened 10 days before planting. 3 lines of the compartment, with the fermented compost and the calcium phosphate mixed soil, the bottom nest is covered with fertilizer, and the herbicide is sprayed against the grass after the soil is covered.
3, transplant
After 10 days, choose soil transplanting on sunny days or sunny days, and watering the roots in time after planting; after planting and living, chase the manure and fertilizer for 1 or 2 times; after 35 to 40 days after planting, re-apply the fertilizer before and after the winter, and apply the livestock per acre. Excreta 2500 ~ 3000 kg + plus urea 20 ~ 30 kg + plus superphosphate 20 kg + add potassium sulfate 15 kg + a small amount of phosphate fertilizer, boron fertilizer or compound fertilizer, open a small hole 15 cm from the plant, the fertilizer water is applied And cover the soil and protect the root; 60 days after the planting, the vegetable is rapidly inflated at the beginning, and the human and animal manure and sewage biogas slurry is added with urea.
Fourth, pest control
1. After sowing the seedlings in the seedbed, spray 40-800 times of pesticides such as dimethoate, sputum, aktai, and oxaloin on the surface of the carton and nearby to kill aphids and ant pests.
2, can be used in the mildew, sputum, sputum, 300-500 times liquid soaking seeds, prevention and control of seedlings in the seedling stage.
3. Spraying 14% solution of 14% nitrogen and copper water, 72% of streptomycin sulfate 2000 times (500 mg/kg), or 3% of bacteriocin WP 1000 times, etc. .
4, viral disease prevention and treatment: the initial stage of the disease can be sprayed 5% plant disease 300 times liquid, or 5% bacteria poison clear wet powder 400 times liquid, or poisonous bacteria stop 500 ~ 800 times liquid and other prevention and treatment.
5, downy mildew: with frost epidemic, Park frost 500 ~ 800 times liquid, or 58% Redolmer or 70% Paterson 500 ~ 700 times liquid spray control.
6, Flea: use 50 ~ 80% dichlorvos EC 8 ~ 1000 times liquid, 50% phoxim EC 1500 times liquid, 40% inulin milk 2000 times liquid, etc. in the young armor spray prevention.
7, mantle: with 50% of sulphur phosphorus 600 ~ 800 times liquid a spoonful of root irrigation.
8, aphids: spray imidacloprid, compound cockroach insecticide 1000 times liquid or with a yellow plate to trap.
