I. Objective To improve the production capacity of vegetables in our town, increase production and economic benefits by promoting new varieties of lettuce and pollution-free high-yielding cultivation techniques, pest control, and formula fertilization.
Second, the type
(I) Promotion and standardized cultivation of improved varieties
(II) Formula Fertilization, Diseases and Weeds Control 3. Main Contents (I) Implementation Location, Scope, Scale, Crop Types: The implementation site is the Baoguan Formation of Pufeng Village Committee of Sanchuan Town, involving 5 households with an area of ​​5 mu. The introduction and promotion of new varieties such as Chundu No.1, No.2 and No.8.
(B) High-yield cultivation techniques
1, nursery
(1) Seed treatment is soaked in warm water of 50-55°C for 10 minutes, and then soaked in clean water for 12-14 hours. Remove and wrap it in a wet towel or sandcloth and moisturize under the condition of 15-20°C. Wash with water once a day, 80% of seeds can be sown.
(2) Seedbed preparation The sand loam soil with convenient drainage and irrigation, loose soil and high fertility is selected as the seedbed. The area of ​​the seedbed is transplanted with an acre of 10 hectares of seedlings in an area of ​​10 hectares, which is conducive to the cultivation of strong seedlings. When the whole seedbed is cultivated, the 10m2 seedbed is applied to a fully rotted high quality farmhouse. Fertilizer 50 kg, seedlings with 70% thiophanate-methyl or 50% carbendazim 8-10 g/10m2 mixed fine soil 15-30 kg, evenly spread in the seedbed for disinfection, so that the fine leveling can be sown.
(3) sowing 1 sowing time: harvesting in autumn and winter, high yield and good quality;
2 Seeding rate: Seedlings for seedbed use 20-30 grams per acre, and the seeding rate per square meter seedbed is 1.5-2 grams;
3 sowing method: before planting foot sowing water, so that after soaking in the water after sowing, in order to spread the seeds evenly, can be mixed with appropriate amount of fine sand for sowing, after sowing covered 0.5 cm of fine soil.
4 seedling management: timely watering to keep the soil moist, pay attention to pest control, do a good job of manual weeding, to the seedlings grow to 5-6 true leaves, timely transplanting.
2. Transplanting (1) Fertilization for soil preparation: Transplanting the field requires intensive cultivation, combined with 2000-3,000 kilograms of fertile and mature farmyard fertilizer per acre, 50 kilograms of compound fertilizer, and 100 kilograms of normal calcium as base fertilizer. It is required to open the car for planting. Generally, the car width is 1.2 meters (planting 4 lines) or 1.6 meters (planting 5 lines), and the ditch width is 0.4 meters. The winter transplanting can be covered with a plastic film. The car width is determined according to the width of the plastic film.
(2) Transplanting and density: When the seedlings are 10-15 cm in height, 5-6 leaves can be transplanted, and as far as possible, the plants are transplanted on cloudy days and evenings with mud. The spacing of transplanting lines is 33 40 cm per mu. Planting 5000-5500 strains.
3. Field management (1) Irrigation: Immediately after transplanting, root water shall be poured and water shall be poured continuously for several times until the watering is stopped and watering is stopped for one week to carry out seedlings. Water and fertilizer management shall be strengthened after the end of seedlings. Lettuce tissue is soft, afraid of dry taboos, keep hydrated in the early stage of vegetative growth, and promote the growth of roots and rosette leaves. The stem swell period should be fully water supply, can not be affected by drought, but can not gnaw, uneven dry and wet and easy to crack, mining Before the harvest, irrigation should be stopped.
(2) Top-dressing: seedlings combined with irrigation, applying 10 kg of urea per acre to raise seedlings, followed by two stages of rosette and stem enlargement, 25 kg per mu for compound fertilizer or compound fertilizer, and dihydrogen phosphate Potassium concentration 0.2% for foliar spray 2-3 times. One month before the harvesting of lettuce, combined irrigation with 100 kg of ammonium bicarbonate per acre for flushing.
(3) Pest control: Less is used for insect pests, generally locusts and spotted lilies, 50% anti-influx WP 2000 times, 70% ciprofloxacin 8000x spray control; the disease is mainly downy mildew, available 50 % carbendazim WP 800 times or 58% metalaxyl MnZn WP 500 times or 50% diacyl morpholine WP 500 times, or 75% chlorothalonil wettable powder 600 times spray control, Once in 7 days, use it alternately, even for 3 times.
4. Timely harvest When the lettuce leaf and the outer leaf are at the same time, the harvest can be harvested. If the harvest is not timely, the growing point will continue to grow bolting, thereby reducing the value of the commodity. The roots and the lower outer leaves are cut off to retain the upper leaves when harvesting. Can be listed for sale.
