Into the month of October, Chinese cabbage grows into the heart period. After field inspections, the incidence of cabbage diseases and insect pests is now lighter than in the same period in recent years. However, due to the thunderstorms and overcast days in Beijing in August and September, the growth in the early period was weak; for the Beijing climate change in October, generally 10 At the beginning of the month, it was easy to appear even cloudy days, which determined that the management of water and fertilizer in the cabbage during the autumn of this fall was mainly to promote the development of the disease, and to strengthen the control of pests and diseases to ensure a good harvest of Chinese cabbage this year. First, the Baoxin period is the peak growth period of Chinese cabbage leaf weight, and the middle-late-maturing varieties such as Beijing No. 3, etc. The growth weight of the Baoxin period accounts for about two-thirds of the entire growth period. The water and fertilizer management work must be done well. 1. Irrigation requirements: In October, the amount of rainfall is small and the water consumption is larger than the previous period. It must be supplemented by irrigation. In particular, the water content of leaves of Chinese cabbage accounts for 95%-96%. Therefore, it is particularly important to strengthen water management during the core period. The specific requirements are: the first water should be small during the filling period, and the growth of plants will be harmed when the water volume exceeds the general level; the first water will enter the normal irrigation after 4-5 days, and the water will generally be 5-7 days, and the amount of water will not be less than 30 per time. On the other hand, for the sandy loam planting, the watering interval should be 5-6 days; the watering should be stopped one week before the chopping of vegetables; the first is to avoid too much moisture from being stored, and the second is to facilitate harvesting and reduce the damage caused by mechanical damage. 2. Top dressing requirements: After entering the filling period, cabbage has been sealed and ridged. In order to reduce the mechanical damage caused by manual operations, the top dressing should be based on the flushing fertilizer. The first top dressing is applied before cold dew. The second time in the middle of the month (a few days before the frost) chasing a fat. During this period, the temperature gradually decreased, so that the fertilizer utilization rate was reduced. The nitrogen fertilization is the most suitable for fertilization. Generally, ammonium sulfate is used. It is advisable to use 15-20 kilograms per mu, followed by irrigation with water. The amount of top-dressing should be increased appropriately for lands with a slightly lower degree of baggage. Second, pest and disease control: Chinese cabbage should focus on the control of downy mildew, black spot, soft rot, black rot, bacterial angular spot, aphids, cabbage caterpillars, beet armyworm and so on. Requires symptomatic medication, scientific and timely prevention. Spraying should be thorough and meticulous, and both sides of the leaves should be sprayed properly. According to the law of insect occurrence, scientific medication. For example, the pests against the moth caterpillars need to be carried out in the morning and in the evening, and their daily life patterns are nocturnal, such as poor day-to-day control. Combination of chemical control and physical control, conditional use of insecticidal lamp or yellow board to kill pest control. Specific medication: (1) Disease control: Downy mildew: 72% cream urea manganese zinc wettable powder 600-800 times liquid; or 69% ank manganese zinc wettable powder 800-1000 times liquid; or 72% crocodile Wet powder 600 times spray control. Black spot: 50% acetaminophen wettable powder 1000 times; or 80% wettable powder 600-800 spray. Soft rot and black rot: 72% of agricultural streptomycin can be used 4000 times, or 77% can be used to kill WP 500 times. It was found that the soft rot and black rot disease strains should be removed in a timely manner, brought out of the field and deeply buried, the diseased spots should be disinfected with quicklime or pharmacological agents, and soil should be compacted to prevent the spread of germs after watering or raining. Bacterial angular spot can be treated with neemectin 4000 times solution. (2) Insect pest control: The control of aphids can be 2000-2500 times of 5% pyrethrin EC emulsion, or 25% of Aketai water dispersible granules 6000-8000 times solution; the control of Spodoptera exigua can use 1.8% abamectin 3000 times solution; The control of diamondback moth and cabbage caterpillar can be used as 2.5% vegetable suspension agent 1000-1500 times solution.
