What to Do About Continuous Garlic Cropping? Detailed Explanation of Prevention and Control Methods
Question: Because garlic has been planted for many years, the garlic in the field now gets sick every year, and the bulbs get smaller year after year. Changing the seed garlic does not help. Is it a problem with the soil? What should be done? Answer: When garlic is continuously cropped for many years, various soil-borne diseases and root maggots worsen year by year, which can easily lead to garlic disease and poor growth. For the above fields, it is best to practice paddy-upland rotation of garlic with rice, or rotate garlic with non-garlic upland crops for more than 3 years.

Introduction to the characteristics of the Zhongnong No. 1 garlic variety
According to the latest research by the Garlic Research Institute of the Chinese Academy of Agricultural Sciences, Zhongnong No. 1 garlic, a new garlic line combining high yield, disease resistance, cold resistance, resistance to continuous cropping, and superior quality, has recently passed yield measurement and acceptance by relevant experts, achieving an average yield of 700 kg of garlic scapes per mu and up to 3075 kg of fresh garlic bulbs per mu. Zhongnong No. 1 garlic is an outstanding achievement of a high-tech research program in China titled "863," with a diameter reaching 11.5 cm. This variety has a plant height of 90-100 cm, a plant spread of 40 cm,

Introduction to the Characteristics of the Zhongnong No. 4 Garlic Variety
Zhongnong No. 4 is an early-maturing hybrid garlic that reaches market 15-20 days earlier than ordinary garlic. It generally bolts around Qingming Festival, with large volumes coming to market from April 10 to April 30. The yield of garlic scapes is 1000-1500 jin per mu. Fresh garlic comes to market around May 1, with bulbs 5-7.5 cm in diameter and a fresh garlic yield of about 5000 jin per mu. In 2006, the revenue per mu was 6000-8000 yuan.

Detailed Introduction to the Garlic Variety Zhongnong No. 3
Zhongnong No. 3 garlic seeds were carefully bred by the Garlic Research Institute of the Chinese Academy of Agricultural Sciences. Zhongnong No. 3 garlic produces an especially high yield of garlic scapes; the yield per mu easily exceeds 1500 jin, and with high yields it can reach 1800-2000 jin. The scapes emerge uniformly, creating a truly spectacular sight, and they are crisp and easy to pull without becoming tough. The scapes are thick and sturdy, with 12-14 scapes per jin. The fresh garlic yield is 5000-6000 jin, the largest bulb diameter reaches 10 cm, and 95% of bulbs are over 6 cm. The bulbs are spherical and semi-tall in shape, with a neat appearance, bright color and glossy sheen

Garlic Seed Selection and Saving Methods and Key Technical Points
Garlic is propagated by using the bulbs as seed. For seed saving, choose bulbs with thick, sturdy stalks, deep green leaves, a good root system, no pests or diseases, and that are large and plump. At the same time, pay attention to timely harvesting. If the bulbs are harvested too early, the cloves will not be plump or firm, and when planted the following year they will have weak germination vigor, uneven emergence, and leaves that curl into tubes without opening; if harvested too late, the outer skin of the bulbs will split, and many cloves will scatter. The harvest time is generally best 25-30 days after the garlic scapes are harvested. At harvest, the aboveground part should have four or five leaves, the cloves should be countable by hand as raised bumps, and the outer skin should be purplish red. When harvesting garlic bulbs, you must

Methods and key technical points for rational close planting of garlic
How should garlic be rationally close-planted? Before sowing, the planting density must first be determined, that is, the number of plants per mu. According to trials in the Cangshan garlic production area, on plots with medium to high production levels, planting 30,000 plants per mu yielded 686.7 kg of fresh garlic bulbs; planting 40,000 plants per mu yielded 920 kg of fresh garlic bulbs, a 33.9% increase over planting 30,000 plants; planting 45,000 plants per mu yielded 526.7 kg of fresh garlic bulbs, a 23.3% decrease. The trials found that when the number of plants per mu exceeded 40,000, although the yield increase was significant, the commercial

What are the clever uses of garlic in agricultural production
1. Preventing and treating fish gill rot disease and enteritis disease. For every 100 kg of fish, use 10 ml of allicin, mix it into the bait and feed, with 3 days as one treatment course; or for every 100 kg of fish, use 200 g of 10% synthetic allicin daily, mix with bait and feed for 6 consecutive days. 2. Preventing and treating explosive hemorrhagic disease in fish. For every 10,000 fish fry, use 0.25 kg of garlic, 4 kg of alligator weed, 0.25 kg of salt, and grind with soybean cake and feed, twice a day for 4 consecutive days, with obvious results. 3. Preventing and treating hemorrhagic disease in grass carp. For every 50 kg of fish, use 5 kg of water peanut

Detailed Explanation of Garlic Cultivation Systems and Cultivation Seasons
For autumn-sown garlic, rice, corn, sorghum, wheat, beans, cucurbits, tomatoes, and potatoes are good preceding crops; for spring-sown garlic, autumn snap beans, pumpkins, solanaceous vegetables, cotton, and legumes are preferable. Garlic requires large amounts of fertilizer during its growth period, and garlic roots can secrete substances with a certain bactericidal effect, so it is also an ideal preceding crop for other vegetables. At the same time, it can also be intercropped and relay-cropped with corn, cotton, medicinal herbs, and various vegetables. In Northeast and Northwest China, garlic is mainly grown as a sole crop; in North China, the customary practice is intercropping and relay cropping with other vegetables and grain crops.

What are the two major problems commonly seen in garlic cultivation?
In recent years, in the main garlic-producing areas such as Jinxiang, Juye, Cangshan, Zhongmu, and Kaifeng, quite a few problems have arisen from a series of causes including continuous cropping, poor management, and unscientific fertilization. They can be summed up in 9 words: "yellow leaves, dry tips, dead seedlings, low yield." The author now introduces to the broad ranks of agricultural technology extension workers and garlic growers the causes of the two most headache-inducing problems that have appeared in garlic cultivation in recent years. Problem one: the garlic looks normal before winter, with a few yellow leaves and dry tips, but after green-up the garlic seedlings turn severely yellow.

What are the key technical points for garlic cultivation? A detailed explanation in one article
Garlic is a bulb vegetable of the onion family, with strong cold tolerance, an optimum growth temperature of 12-25°C, and is a long-day crop. It is suitable for planting in fertile, slightly alkaline soil rich in organic matter with convenient irrigation and drainage. To grow garlic, the main steps to get right are as follows: (1) Variety selection. At present, the main varieties suitable for planting in Qilin District are Sichuan Red Seven Stars (first generation, second generation), Soft-leaf Garlic, First-grade Early, Second-grade Early, local purple-skin garlic, etc. (2) Sowing time. In the flat basin area, early garlic sprouts and Red Seven Stars (first generation, second generation) are generally planted around the White Dew solar term (early September
