Autumn eggplant pollution-free cultivation techniques

First, choose a suitable area. The most suitable area for pollution-free autumn eggplant cultivation is the average temperature of 16-18°C in July; the suitable area is the average temperature of 18-20°C in July. The average temperature in October is not lower than 9.5°C. The planting area should be selected from the production areas that are not affected by pollution sources or whose pollutant content is within the allowable range. At the same time, fertile soil, deep soil, loose texture, and good drainage and irrigation should be selected.

Second, suitable varieties. According to the consumption habits of the main sales market, select the varieties that are marketable, high-quality and high-yield, more resistant to M. blight, brown-spot disease, and verticillium wilt. Such as the 黔 黔 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 3 黔 黔 黔 黔 黔 黔 黔 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。.

Third, nurturing strong seedlings.

1, suitable sowing date. According to tests, the suitable sowing date for the regions with an average temperature of 16-18°C in July is 10-17 May; the suitable sowing period for the regions with an average temperature of 18-20°C in July is 20-27 May; the average temperature for July The suitable sowing period for 20-21°C is May 30th - June 7th.

2, sowing the whole bed. Select soils that have not been planted with potatoes, flue-cured tobacco and solanaceous fruit crops for more than 4 years to be used as seedbeds. Before sowing, add 30% of fully decomposed human and animal urine as base fertilizer, and sprinkle a layer of grass ash. When sowing seeds and soil, 7 g/m2 Bacterial seedlings should be planted after mixing well and the seedlings should be planted in an amount of 30-35 g/mu. After sowing, they should be covered with shade nets or shade sheds to facilitate emergence.

3. Strengthen seedling management. Two to three seedlings were planted at seedling stage to remove too dense and weak seedlings. The nursery period coincides with the rainy season and the humidity is high. Special attention should be paid to the prevention of damping-off and blight, and watering should be avoided. The diseased seedlings should be removed immediately after the disease occurs, and appropriate amount of plant ash should be controlled to spread. In addition, avoid stubborn roots and seedlings. Seedling seedlings grow well under conditions of 1-2 times light human urine, age 35-40 days, selected sunny evening or cloudy days.

Fourth, the whole compartment, fertilization, planting. Eggplants are afraid of crickets, taboos, and should not be densely planted. They are poorly ventilated under the shade of each other, are susceptible to disease, and have poor quality and low yields. It is better to plant in deep-gutter and narrow-gauge cars with a width of 83 cm, a height of 18-25 cm, a ditch width of 40 cm, and planting of 2 rows. Line spacing 50 cm 43 cm, 2100 plants / acre is appropriate. Eggplant harvesting period is long, need more nutrients, combined with weak root regeneration ability, should pay attention to deep plow basal fertilizer, hole application or ditch decomposed organic fertilizer 2500-3500 kg / acre, compound fertilizer 50 kg / acre or superphosphate 40 Kilograms/mu, grass ash 50 kg/mu, banned urban waste fertilizer.

Fifth, Daejeon Management.

1, scientific fertilizer. Eggplant grows for a long period of time. Reasonable top-dressing is one of the main measures for high-quality and high-yield production. The application of standard nitrogen fertilizer should not exceed 20 kg/mu. After the colonization and survival, it was applied 1 times of decomposing and lightening of human and animal urine; when the root eggplant cherries were large, the second fertilizer was applied, and 20% of livestock and manure water or urea applied 6-8 kg/mu, potassium chloride 7 kg/mu; When the eggplant is 5-8 cm long, the third fertilizer is reused, and 30% of the animal manure water or urea 8-10 kg/mu is used; after the eggplant is harvested, the 4th fertilizer is applied topically, and 30% of the manure is used. Urine or application of 6-8 kg/mu urea; the results of the later visual growth, topdressing with manure urine, or with potassium dihydrogen phosphate 600 times sprayed 1-2 times, to promote the late prosperous .

2, pick leaves. After the plants are sealed, old leaves, diseased leaves, and yellow leaves are removed in time to facilitate ventilation and light transmission to reduce the spread of pests and diseases.

3, cultivator soil. The early cultivator should be deep and shallow in the later period. When the height of the plant is about 40 centimeters, soil should be cultivated to prevent lodging.

4, irrigation and drainage. Eggplant leaf area is larger, more water evaporates, the soil needs to maintain sufficient water, in order to produce high quality and excellent quality. Especially in the drought-suppressing period, it is a time when the autumn eggplant fruits are growing. The water requirement is the most. Watering must be done in time to meet the needs. When there is too much rain, it is necessary to promptly clear the drainage of the ditch, reduce the humidity in the field, and reduce the occurrence of diseases.

Sixth, comprehensive prevention and control of pests and diseases. Autumn eggplant cultivation, Daejeon's diseases mainly include M. blight, Brownie disease, Verticillium wilt; Insect pests mainly include eggplant macular pupa, tea scutellaria root, and agricultural control measures and pharmaceuticals should be used for comprehensive prevention and control.

1. Comprehensive prevention and control of agriculture. Seed disinfection: soaking for 2 hours with 500 times solution of carbendazim, soaking for 6-8 hours with 2000 times thiophanate solution of about 55°C, washing with clean water, drying, or using 80% Fumei double dressing ( Dosage amount 0.2%). Use resistant varieties. With 3-5 years of rotation for non-solanum crops. Deeply turn the land, strengthen management, pay attention to trench drainage, timely cultivating, weeding, earth-cultivation, rational fertilization, watering, prevent plant growth during fruit period; timely removal of old leaves, pests and leaves, over dense leaves and rotten eggplant, timely Dispose of sick plants, do a good job in idyllic cleansing and reduce the source of pests and diseases.

2, pharmaceutical control. The timely and appropriate use of high-efficiency, low-toxicity, low-residue pesticides, seizing the key period of prevention and control, minimize the use of pesticides and the number of times.

Blight and brown sphagnum were sprayed with 500% 65% foumoxane or 1:1:150 Bordeaux mixture at the seedling stage; the result was 75% chlorothalonil wettable powder 600 times, or thiophanate-methyl 600 Times, mancozeb 500 times two doses, or 1:1:100 times Bordeaux mixture, continuous control 2-3 times.

Verticillium wilt was treated with 50% carbendazim WP 2 kg before planting, transplanted with 150 T. hirsutum roots and then transplanted, and then treated with 30% DT suspension 350 times to irrigate the roots. 50% carbendazim, or thiophanate 500 times Irrigation.

Solanum macularis, administered before 10 o'clock in the larval stage, was sprayed with 20% cypermethrin 2000 times, or 10% chrysanthemum cream 1500 times, or 50% phoxim EC 1000-1200 times. The focus is on tender stems, shoots, buds and fruits. At the same time combined with manual killing.

Astragalus membranaceus uses 73% Creutine EC 1500-2000 times solution, or 20% chloric mitochondrial EC 1000 times, or 25% chlorfenone WP 1500 times, also available 50% sulfur suspension 200-300 times. Pay attention to the alternating use of pesticides, focusing on the prevention of heart leaves, tender stems, leaves, flowers and young fruit. Pay attention to the spray table.

Seven, timely picking. Candelaria generally picks 23-25 ​​days after flowering. The best time is in the morning or evening. The collection is too early, the yield is low, the harvest is too late, and the pulp is rough, which affects the later yield. The pesticide safety interval is strictly enforced during harvesting.
