In North China, the sowing date for garlic is generally from late September to early October, and the upper and middle sentences in November begin to sleep over winter. Due to the high temperatures in October-November 2006, garlic did not begin to overwinter until mid-December. This situation is equivalent to a one-month advancement of sowing, so garlic is currently producing a prosperous phenomenon, which will seriously affect the yield and quality of garlic. The best leaf age of garlic seedlings exposed in winter is 4-5 leaves. At this time the plant height is about 25 centimeters, about 30 roots, the cold resistance of the plant is the strongest, the winter is not easy to freeze damage. The jujube year is the vegetative and reproductive growth stage of this plant, with good growth and development, large vegetative body, the largest photosynthesis area, and the largest photosynthetic area formed early, with the highest yield. This year due to the October-November high temperature, the leaf age is generally too large, in the 8-10 leaves, due to large pre-winter nutrition, excessive nutrient consumption, cold resistance decreased, if the early spring has a strong cold air intrusion, will Severe frost damage occurs. Under normal circumstances, the garlic begins to “rotate†when it is 5-6 leaves, and the kind of garlic rots. The nutrient supply for the growing seedlings is completely cut off. At this time, the absorption function of the root system is not yet sound, and the nutrition produced by the blade is not sufficient. Due to malnutrition, the tip is starved to death. This phenomenon is inevitable. Generally, when rotten mothers are used, the time value is spring, and watering and top dressing are more timely in the management, so the harm is not great. However, in October-November 2006, there was less rain and snow, and fertilizers were not applied in time. The soil was dry and lack of water, resulting in the death of 3-4 leaves in the lower layers, and the plant growth was weak and affected the yield. If the plants are too large, if the management can not keep up in the spring, the growth and development of the later plants will easily lead to premature aging and affect the increase of yield. During winter, the plants are too large and the apical buds enter the axillary bud differentiation stage. The differentiated buds may also become vernalized again, forming double-vegetable garlic in the following year. That is, garlic cloves are covered with small garlic cloves, which seriously reduces the quality. In order to reduce the damage and damage caused by garlic, the following management measures should be taken in the early spring of this year. 1. As soon as the soil is thawed, it will be poured back to Qingshui early to avoid spring drought. 2. Combine the pouring of Qingshui and redistribution of 200 g of soil conditioner. After about 20 days, the 50-80 cm deep soil can be loose and transparent, promoting root growth and development. 3. In combination with watering, top-up 25 kg of potassium sulfate compound fertilizer to promote growth and development. 4. Spray plant growth regulators. When returning to green, one ten-thousandth of a solution of Natural Phytolide-Shuonfeng 481 is sprayed to promote photosynthesis of leaves and create more nutrients and reduce malnutrition. 5. Control pests and diseases. Spray 68.75% of epoxifen dispersible granules 1000 times; or 72% Kelu wettable powder, 75% killing 1000 times suspension of 600 times liquid to control leaf blight, downy mildew. Carbendazim Irrigation to Control Root. With avermectin, imidacloprid irrigated root knot nematode, root lice. Disclaimer: Some articles in this website have been transferred from the Internet.
