1 variety selection
Variety selection of baby food sown in spring: Choose the anti-seizure varieties with better cold resistance, such as Gao Liyu dolls, mini stars and so on.
Variety selection of baby food sown in summer: Select disease-resistant varieties with better heat resistance and early packaging, such as Libebe and heat-resistant 55 varieties.
Variety selection of baby foods planted in the fall: The variety requirements are not very strict, but no matter which season you plant baby food, you must choose the species that suits the needs of the local market. At the same time, you should pay more attention to the variety of fast-growing, well-proportioned, up-down, etc. Crude, disease resistance and other points.
2 temperature requirements
The baby food belongs to a semi-cold vegetable plant, the suitable growth temperature is 5-25 degrees, the suitable temperature for seed germination is 25 degrees, the suitable temperature for the growth of leaves and leaf bulbs is 15-20 degrees, when the temperature is 10 degrees, the growth is slow, when Temperatures below 5 degrees are susceptible to freezing injury, while temperatures above 25 degrees are susceptible to viral disease.
3 Fertilization
In the cultivation of baby food, at the same time as applying basal fertilizer, 10-15 kg of compound fertilizer should be applied as the base fertilizer per acre, and 15 kg of superphosphate should be added to the calcium-deficient or partial alkali soil. This is beneficial to the baby food plant. Absorption of calcium. During the whole growth period of the baby food, the top dressing is combined with irrigation, and a small amount of topdressing nitrogen fertilizer is used as the seedling fertilizer at the seedling stage. When the plants enter the continuous cropping period, more fertilizer is needed. Topdressing urea and potassium sulfate is 10kg per mu. Or ternary compound fertilizer 20kg a total of 12 times, while spraying 0.2% potassium dihydrogen phosphate two times, the baby-bearing plant after the ball needs to be based on the specific growth conditions of the plant fertilizer.
4 watering
When the seedlings are dry, they need to be watered with little water. At other times, water is generally not used to keep the soil moist. In the early stage of the baby food, the lotus seedlings should be properly controlled, and the water should be timely irrigated after the seedlings are finished, so as to avoid the influence of drought on the water requirement of the vegetable growth. The continuous cropping period of the baby food is the peak period of the plant water requirement, which requires a small amount of water to be poured, so that the ridge surface does not see water, the root system does not lack water, and it is necessary to pay attention to the fact that the water cannot be flooded and the plants are prevented from growing in length, making the air humidity excessive and taking place. Some diseases. Stop watering the baby dish one week before harvesting.
5 Pest control
5.1 Disease
Although the growth period of the baby food is short, it is prone to diseases due to improper management. Common diseases include anthrax, downy mildew, and soft rot. Anthracnose and downy mildew can be treated with zesin zinc and anthraquinone omeprazole wettable powder; soft rot can be used for agricultural streptomycin, antiviral control, dose concentration are used according to instructions, 7d spray 1 time, even spray 2~3 times .
The common diseases of baby food are anthracnose, downy mildew, and soft rot. For anthracnose and downy mildew, it can be controlled with dexamethasone and anthraquinone omeprazole wettable powder; soft rot can be treated with agricultural streptomycin, antiviral rot. ,Spray spraying once every 7 days for 2-3 consecutive days. It should be noted that the concentration of the drug should be used according to the instructions. Do not increase the concentration of the drug.
5.2 Insect pests
The common diseases of the baby food are diamondback moth and aphids. For the diamondback moth, it can be used to prevent and control the young larvae of the diamondback moth at the beginning of spring with 25% to 3,000 times of 1.8% avermectin EC, and 1000 to 1500 times of 5% pyrethrin EC. Use wolfberry net smoke agent 350g/mu fumigation, or use 20% cypermethrin EC 2000~3000 times liquid, 10% imidacloprid wettable powder 1000~2000 times liquid alternately spray control.
