Key points of High-yield cultivation techniques of garlic in Midu County

I. Variety selection

The garlic varieties suitable for cultivation in Midu County are mainly dry garlic, Red Seven Star, Wen Erzao, early and late garlic in the second season, and 120Mu 150kg per mu.

II. Selection of land blocks

Garlic fields should choose fields with high pit, high fertility, deep soil layer and convenient drainage and irrigation.

III. Arrangement of plots

First of all, turn the soil deeply, dry the field, and level the land, which requires that the soil is fine and the ditch is deep.

Fourth, sow seeds at the right time

Sowing garlic at the right time can promote early growth and rapid development, early bolting and high economic benefits. However, early sowing garlic has serious leaf blight and premature senescence, and late sowing leads to weak seedling potential, late bolting and low yield.

The suitable sowing time in Midu County is from September 25 to October 15, which can be sowed early in warm and cool areas and postponed in warm areas.

V. Fertility management

Garlic has shallow root distribution, weak regeneration ability, and is not tolerant to drought and waterlogging. Therefore, according to the conditions of soil moisture and precipitation in each period of garlic growth, timely and appropriate amount of water should be irrigated, and water should be watered twice after sowing to ensure that the seedlings are uniform, and the soil water capacity in the field should be controlled in the mother stage after seedling completion, and drainage should be carried out in time after heavy rain. In the whole growth period of garlic, it is generally necessary to irrigate 6 times for 8 times, and fertilization combined with irrigation.

Garlic has a large population, a long growing period, and a large amount of fertilizer. Generally speaking, 3000 kilograms of rotten high-quality barnyard manure is applied per mu, especially in continuous cropping fields, more organic fertilizers should be applied. Base fertilizer is generally applied with 50 kg N:P:K=15:15:15, 5 kg borax, 2 kg zinc sulfate, and one application of chemical fertilizer and stable fertilizer, and 30 kg per mu of high-efficiency compound fertilizer, 10 kg urea and 25 kg potassium sulfate respectively after the mother stage (4 mi 6 leaves) and bulb differentiation stage (9 Mel 11 leaves).

VI. Prevention and control of diseases, pests and weeds

Watering thoroughly after sowing, 45 grams of diuron and 45 kilograms of water are sprayed evenly to control weeds per mu when the field water is dry, and it can also be sprayed before the three-leaf stage of garlic seedlings to achieve weeding at the seedling stage.

The main diseases of garlic are leaf blight, purple spot, gray mold, rust, white rot and so on. The main pests are onion scale moth, thrips, Liriomyza huidobrensis and so on.

To prevent the disease, you can choose 10% Shigao powder 1500 times, 25% Shibaoke EC 1000 times, or 25% carbendazim, mancozeb, dilute acylmorpholine, prochloraz and other agents, which should be used alternately once every 10 days.

Insecticides use 5% methylvitamin salt 100 milliliters per mu, or choose pesticides such as imidacloprid, cystamine, alfordine, black light or pyrethroids.

7. Timely harvest

The garlic moss is picked in time when the garlic moss is caught, and the garlic is harvested about 15 days after the garlic moss harvest. Garlic is graded and bundled and preserved in the shade.
