In November, there are two agricultural solar terms, Lidong and Xiaoxue, and the growth of Zanthoxylum bungeanum gradually enters the dormant period of overwintering. "Autumn tube, winter tube leaf", this month's green pepper field tube technical key recommendations are as follows:
1. Physiological differentiation of flower buds, pay attention to ground temperature and weather. The temperature in the city is gradually decreasing, and the average temperature this month is 12 ℃ ~ 17 ℃; the soil temperature of the cultivated layer in November is mostly 15 ℃ ~ 18 ℃. This month, Green Zanthoxylum bungeanum is in the period of physiological differentiation of flower buds, the total inflorescence axis continues to increase, and secondary and tertiary inflorescence axes appear; the flower buds continue to differentiate, and the flower bud primordia continue to increase; the sepal differentiation characteristics are obvious.
2. Wipe buds, topping at the right time, and pay attention to fallen leaves. After pressing the branches, many branches have changed the growth direction, effectively promoting the lignification of the resulting branches. In order to promote the growth of fruiting branches and adjust the nutrient balance of the tree, the new shoots or shoots should be wiped from the base in time this month. Later this month, the new shoots have entered the dormant period. A small tip should be removed to control the prolonged growth of the shoots, promote the growth of the branches and increase the fruit setting rate in the coming year. When topping, it should be cut short at the lignified branch, and the length of the branch should not exceed 1.6m.
3. Loosen the soil and clear the garden, prevent and control diseases and insects. In November, attention should be paid to loosen the soil and clear the garden, remove the ground moss, and increase the air permeability of the soil; at the same time, adopt the method of soil cultivation or soil pressing to increase the thickness of the soil of the tree tray. Key points for pest control this month: (1) Pepper aphids. In the early stage of aphids damage this month, you can use 70% imidacloprid 3000 times solution to spray for prevention and control to quickly control the spread of aphids. (2) Zanthoxylum bungeanum leaf spot disease. Generally, the old leaves at the bottom of the branches occur first. At the initial stage of the disease, punctate chlorosis spots appear on the surface of the damaged leaves. Later, the diseased spots gradually turn into small round spots of gray to grayish brown. When the disease is severe, leaves fall off, resulting in insufficient nutrient accumulation, poor differentiation of flower buds, and reduced yield. In the early stage, Zhengsheng 1000~1500 times liquid or antibiotics can be used for prevention and treatment.
