When planting garlic in autumn, many farmers often encounter problems such as slow emergence of seedlings, few seedlings, lack of seedlings and ridges. These are all related to sowing technology, and some farmers have misunderstandings when planting, resulting in low garlic yields and many diseases. If you want to have a high yield of garlic, what aspects should you pay attention to when planting?
1, the sowing temperature should be appropriate
The sowing time of garlic is very critical, sowing early, seedlings growing before winter, consuming too much nutrients, and not resistant to freezing. Some farmers sow seeds relatively early every year, but they have not increased their yields, but the ground temperature is high, and the damage of ground maggots is more serious. The seeds are sown late, the seedlings grow slowly, have few roots, and have low cold resistance. The climate of each region is different, when sowing, it depends on the local temperature situation, the average monthly temperature is 22 ~ 25 ° C, suitable for garlic germination, and leaf growth. Seeding is generally started in mid-to-late September to October, and garlic is planted a week later.
2. Proper dense planting can increase yield
The sowing depth of garlic should also be suitable, when the planting is too deep, the seedling time is late, and the root system absorbs more water and fertilizer, and the growth is strong. When planting, the sowing density is determined first, and then the garlic cloves are inserted into the soil, the tip is slightly exposed, and then covered with two centimeters of soil, slightly compacted, and the soil is closely connected, which is conducive to the water absorption of the root system. When garlic is sown, proper dense planting can increase yield, but some plots use a relatively large amount of seeds and are planted too densely, resulting in small garlic heads and poor quality. In general, when the row spacing is 20 cm, the plant spacing of early maturing varieties is 7 to 8 cm, and the plant spacing of late ripening garlic is 9 to 12 cm.
3. Seed mixing to prevent pests and diseases
Before sowing garlic, it is necessary to do a good job in the prevention of diseases and insect pests. Now most plots will be replanted with garlic, garlic maggots and soil-borne diseases are becoming more and more serious, and the prevention effect in advance is better. There are two ways to control pests and diseases that farmers can refer to, that is, seed mixing or soil treatment.
When garlic is mixed, the insect-proof ingredients are imidacloprid, thiamethoxam, and the disease-proof ingredients are phenylethicazole, pentanazole, and roxonitrile. The addition of brassicain is beneficial to improve the emergence rate and the disease and insect resistance of seedlings. Garlic seed anti-insect and disease prevention effect is good, long effective period, and more convenient, more disease and insect plots, it is recommended to mix seeds. If there is no seed directly planted, it can be treated with soil, mainly used to control garlic maggots, and sprayed with agents such as chlorpyrifos or octyl thiophosphorus to prevent it in advance.
When sowing garlic, we should pay attention to the temperature at the time of sowing, not sowing too early, nor should it be sown too densely, and at the same time pay attention to preventing diseases and insect pests, and mix seeds in advance. In this way, it can be conducive to the emergence of garlic seedlings, grow strongly, and lay the foundation for high yields. If you have no planting experience, you can refer to the above methods when sowing.
