Wheat, spinach, wax gourd, corn, and celery are cultivated five years a year. While ensuring food production, the planting area of ​​vegetables is increased, the multiple cropping index is increased, and the light and heat resources are fully utilized. Significant. This model can receive 350 to 400 kg of wheat per mu, 800 to 1,000 kg of spinach, 3,500 to 4,000 kg of wax gourd, 550 to 650 kg of corn, 5,000 kg of celery, and 6,000 yuan per mu.
First, mouthwash and specifications
After the autumn crops were harvested, they were promptly exterminated, the foot pods were made, the fine soil preparation was repeated, the basal fertilizers were reused, and the fertilization was balanced. Generally 5000 mu of high-quality organic fertilizer per acre, 50-60 kg of ammonium bicarbonate, 30 kg of diammonium phosphate, 20 kg of potassium sulfate, appropriate amount of zinc, boron, manganese, magnesium and other micro-fertilizers and organic fertilizer or diammonium, potassium sulfate mixed Evenly, spread. After the fine soil preparation, press 160 cm to make it flat. Six rows of wheat are planted on one side of the flat, occupying an area of ​​about 100 cm. The spinach was sown on the other side and sowed on the loquat. The spinach was harvested before wintering or after returning green. In early March, the wax gourd was fed with the Yangshuo nutrient pod. In mid-April, the mulching was used to cover the original spinach planting line, and the single row was planted. , spacing 40 cm. Before the harvest of wheat, one row of corn was sowed on both sides of the plant. Before the harvest, celery was grown between the big corn rows in early August and harvested at the end of November.
Second, the main cultivation techniques
1. Wheat. The selected varieties such as Jimai 21, Jimai 22, Lianmai 18, and Dwarf-resistance 58 were used, and the planting density should not be too large. Other fertilizer and water management and wheat pest and disease control were planted in the same field.
2. Spinach. The Japanese large-leaved spinach was used. The seeding rate was 3 kg per mu, and appropriate seedlings were planted after emergence to maintain a spacing of 3 cm square. According to growth and market conditions before the winter can be properly harvested. Harvested before the winter can be applied in the 3 to 4 leaves of ammonium bicarbonate, 50 kg per mu; return to the green harvest, should be poured in winter antifreeze well, appropriate coverage of cold (optional cattle cattle manure or broken straw ), After the return to the green, it will be cleared in time, covered with plastic film, and top-dressed and watered according to soil moisture, and finished in the middle and late March of the following year.
3. Melon. After the spinach was harvested, the sluice fertilizer was applied in a timely manner, 2000 kg of soil-fertilizer was applied per mu, and 15 kg of diammonium phosphate was applied. Melon selection of small melon varieties, such as Beijing early maturing melon, a string bell melon, single fruit weight in the 2 to 3 kg variety. In early March, Yangshuo was used to raise seedlings and was covered with plastic film in mid-April. Each row was planted with a spacing of 35 cm and water was planted by watering the hole. Three vines were used for pruning, leaving one main vine and two side vines per plant. After removing all the remaining branches, the first female flower of each vine was removed after the female flower was opened, and the second female flower was selected to sit on the melon, leaving 3-4 melons per plant. Wheat grouting water and wheat yellow water were combined with melon water and swelling melon water. When swelled melon water, quick-acting nitrogen fertilizer was applied. During the growth period, it can prevent and cure the dynamics of bacterial wilt, anthracnose, and powdery mildew. It can be used to prevent and cure large quantities of drugs such as Dasheng, Anthraquinium, Anthraquinone and Mancozeb. Control of aphids, whitefly can use imidacloprid, perfluthrin and other compound pesticides. After sitting on the melon, combined with disease prevention and pest control for foliar application, 0.3% of potassium dihydrogen phosphate and 0.5% of urea can be used. Immediately after the plants are thrown, the autumn vines will be rushed to the wheat husks without pressure, so that the tendrils can freely grasp the wheat hulls. After sitting on the melon, the young melons are under the grass, avoiding direct contact with the ground. The first batch of melons grows to 1.5 to 2 kg in time to facilitate the growth of young melons.
4. Maize. 7 to 10 days before the harvest, wheat was planted on both sides of a row of corn, with a spacing of 25 cm, a small row spacing of about 30 cm, and a large row spacing of about 130 cm. The rows were planted with good ventilation and light transmission. The varieties used were Zhengdan 958, Yandan 20, Yongyan No. 4, Zhongke 11 and other early maturing varieties. Immediately after wheat was harvested, an imidacloprid or acetamiprid was sprayed once in a timely manner to eradicate aphids, as well as locusts and leafhoppers. The corn plants were sprayed with an antiviral agent plus 0.3% potassium permanganate to prevent the disease. When the corn matures, the straw is timely harvested and pared, adding light to the celery. Other field management works with field cultivation.
5. Celery. After the winter melons were harvested, they were rotted in the field in Renqiman and Maijing. They cleared the field in late July and sprayed a fungicide to prevent the disease. Apply 20 kg of diammonium phosphate per mu. Conditionally apply 2,000 kg of high-quality soil-fertilizer per acre. After squating 15 cm, grow celery. 5 days before sowing, celery is soaked with germination, soaked in warm water and rubbed several times, soaked for 12 hours, then drained, drained, placed in a cool place with wet gauze, germinated, and turned several times during pregermination, until 50% of the seed begins to bloom. Watering after sowing, spraying herbicide before sowing, spraying near the ground, try not to spray on the corn leaf. Keep the ground moist before emergence. Appropriately stop the water after emergence. Intermittent seedlings 2 or 3 times. The final seedling spacing is 3 cm or so. (For example, planting celery, because the plants are larger, the fertile seedlings can be transplanted, and planted in rows of 15 cm and 10 cm or Seedlings spaced 15 centimeters apart and 8 to 10 centimeters apart, planting seedlings for 10 to 15 days after planting, when the roots are in large numbers and the plant leaves start to grow upright, the seedlings are completed. Topdressing watering, always keeping the ground moist. Plants 25 cm high At the beginning, foliar spray of 50 mg/kg gibberellin and 0.3% potassium dihydrogen phosphate and 0.5% urea were mixed and sprayed for 2 to 3 times for 10 to 15 days at a time, and the top dressing was stopped 7 to 10 days before harvesting. And watering.
Third, the advantages of the model
Wheat and corn have good ventilation and light transmission, and the disease is reduced. The edge has obvious advantages. The wax gourd does not need to be pressed to save time and labor. The autumn vines and young larvae do not touch the ground, which reduces the pests and diseases; the celery grows in the early corn shading and in the hot summer. Can grow well; various crops require different fertilizer laws, can give full play to the role of soil fertility increase production. In summary, this model is an excellent planting pattern.
Anti oxidation, has the function of delaying aging and resisting fatigue, Astaxanthin can significantly reduce the ROS and NMP on the dermal layer of collagen, elastin damage, to ensure the normal metabolism of the skin, Ginkgo biloba extract can directly eliminate lipid free radicals, lipid peroxidation free radicals and alkyl radicals, and terminate the free radical chain reaction chain.Panax ginseng can be formulated into freckle, reduce wrinkles, activate skin cells, enhance skin elasticity of cosmetics.
