Key Techniques for Four-Season Multi-Cutting Cultivation of Stem Garlic
Stem garlic was introduced from Europe and is a perennial crop of the genus Allium in the lily family. Necklace garlic is sown from seed like Welsh onion. Its stems, leaves and scapes resemble those of common garlic, but it is larger and more robust than common garlic, with strong adaptability; it can withstand high temperatures of 40°C and low temperatures of -15°C, and can be sown in spring and autumn in most parts of our country, remaining evergreen all year round. For four-season multi-cutting cultivation, it can be sown from seed like Welsh onion and the seedlings harvested for market, with 1 cutting harvested 60-80 days after sowing, yielding about 2500 kg per mu. If harvesting garlic scapes, seedlings can be raised in summer and autumn, and after 30 days transplanted at a row spacing of 20 cm x 8 cm; scapes bolt in May of the second year after transplanting, with more than 10 tillers per plant, and every tiller can bolt; scapes can be harvested 4-6 times a year, with continuous growth for 5-8 years, during which excess tillers can be pulled out along with their roots for market; the usual yield is about 1500 kg of garlic scapes per mu and more than 5000 kg of stems and leaves.

How to scientifically control the first generation of the second-brood striped stem borer in single-season rice
Control recommendations 1. For early-sown and early-transplanted single-season rice fields, carry out a full control treatment once from June 20-25, targeting mainly stem borers and small brown planthoppers, and also controlling early-occurring leaf folders and rice thrips. Use 5% fipronil (Regent) suspension concentrate at 40-50 ml/mu, diluted in 30 kg of water for spraying. 2. For fields where rice stripe disease has occurred, on the basis of pulling out and removing diseased plants, promptly apply chemicals to control small brown planthoppers. Use 40% chlorpyrifos (Xinnongbao, Saiben) at 100 ml/mu, diluted in 30 kg of water for spraying, and repeat the treatment after an interval of 5-7 days.
