In the middle and late September, 18 rows of garlic are planted in a 3.6-meter wide loquat, with a smoked row spacing of 18.5 centimeters or 25 centimeters (corn intercropping 25 centimeters), 8 centimeters of plant spacing, and 40,000 plants per mu. Harvesting garlic sprouts in early May of the next year and harvesting garlic in late May. In late April and early May, the line of garlic was interplanted in rows of 5 rows of corn, spaced 80 centimeters apart, 25 centimeters in spacing, 3,300 plants per mu. Harvested in early September.
Garlic selection of varieties used for the ecological area of ​​the species, such as Sheyang white garlic. The kind of garlic must be selected before harvesting. After the garlic seeds are harvested, they are promptly dried for 2 to 3 days and then peeled and peeled. Select good weather before sowing with 50% carbendazim 500 times soaking for 10 to 12 hours, remove and dry after sowing.
Soil preparation fertilization chooses high-slow, organic matter-rich, fertile sandy loam soil. Before the crop was harvested immediately after the harvest, it was about 20 cm deep, and it turned over for more than 15 days. Before sowing, do fertilization and soil preparation, on the basis of 2,000-2,500 kilograms of soil-fertilizer per acre, apply rotted cake fertilizer 75-100 kilograms, garlic-specific fertilizer 50-60 kilograms, machine screw into the soil, mix well, north and south To Jianxi to be broadcast.
Appropriate sowing According to the characteristics of coastal climate, the sowing date of garlic is from September 15 to 25, in order to achieve the wintering standard of “high plant height 25 cm, leaf number 6 leaf 1 heart, root more than 30, pseudo stem 1 cm thickâ€. . Shun to the ditch planting, ditch depth of 6 to 7 cm, according to the provisions of the row spacing upright species, require the uniform direction of the abdomen and back of garlic and direction. After the sowing, the flat ridges and furrows were planted, and the top of the petals were covered with 3 to 4 cm of soil.
Spraying before garlic seedling sowing, every acre with 24% Goer EC 50 ~ 70 ml or 42% Garlic grass net 100 ~ 120 ml water 50 kg soil closed, and then cover every mus forward straw 200 ~ 250 kg .
The fertilizer and water strategy adopted the strategy of “stabilizing phosphorus, controlling nitrogen, and increasing potassium†on the total amount of fertilizers. On the basis of applying basic fertilizer, according to “light application of Miaofei, early application of winter fertilizer, skillful application of green manure, reapplying convulsions. "Fertilizer, Zhuo Shi promoted head fat" principle applies top dressing. Miaomiao fertilizer should be applied in the 2 to 3 leaf stage, mainly available nitrogen fertilizer, urea 10 kilograms per acre or 1500 kilograms of decomposed manure water pour water. Wintering fertilizer should be applied in the middle and late January of the second year of 15 to 20 kg of urea per mu, combined with irrigation antifreeze water. Returning green manure should apply 15 kg of urea or 40 kg of ammonium bicarbonate per mu in mid-March when garlic is about to turn green. Sputum fertilizer should be in mid-April garlic sheath leaves exposed when the urea applied 20 kg per mu, 15 kg of potassium sulfate or 45% of compound fertilizer 40 kg. Promoting head fertilizer immediately after picking, 5 kg of urea and 5 kg of potassium sulfate are applied per acre.
Prevention and control of pests The local garlic pests and diseases are mainly “one pest and two diseasesâ€, namely garlic sprouts and leaf blight, and maculopathy. Garlic sprouts were treated with 50% phoxim 1000 times to root. The disease can be sprayed with 75% chlorothalonil 600 times solution or 25% 100 gram 1000 times solution or 20% urea copper 500 times solution, 7 days once, and spray 2 or 3 times.
Harvested in a timely manner about 25 cm in garlic, white stems, and harvesting at the beginning of a curve. It is usually in the early May. After 18 to 20 days after the harvest, the leaves are mostly dry, the plants are in a soft state, and the garlic is harvested when the false stems are not easily broken.
The selection of good varieties of corn used Denghai No. 3, a large-spike variety with high yield, good resistance to fertilizer, resistance to corn borer, and resistance to rough dwarf disease.
The appropriate period sowing planting in the second year in late April and early May, sowing two healthy seeds in one hole, about 3,300 holes per mu. Suitable for sowing, to ensure that all seedlings are broadcast.
Timely Dingmiao set the seedlings in time after the garlic harvest, to stay small to stay weak, stay weak Jian, 1 hole 1 strain.
Strengthen the management of seedlings depending on soil moisture timely prompt watering. Due to the large amount of fertilizer residue in the previous crop, generally no Miaofei, heavy panicle fertilizer, in the big bell mouth period of 15 to 20 kg of urea per acre. One to two days before tasselling, spray 25 ml of corn sorghum onto the upper leaves. Big bell mouth attention to control corn borer.
Method and Technology of Interplanting Corn with Garlic
Garlic and corn are cultivated one year and two crops, generally producing 750 kilograms of garlic sprouts per mu, 850 kilograms of garlic, 700 kilograms of corn, and a total output value of 3770 yuan per mu.
