What pesticides cannot be mixed with azoxystrobin?
Summary: Azoxystrobin must not be mixed with organophosphorus pesticides, such as chlorpyrifos and dimethoate, nor with organosilicon, emulsifiable concentrate, or microemulsion pesticides, and must not be mixed with strongly alkaline or strongly acidic agents, because azoxystrobin has relatively unique properties and should be applied alone as much as possible.

Can Pomelo Be Grown in the North? Key Growing Conditions Explained
Summary Pomelo cannot be grown in the north, because pomelo needs to grow in a warm and humid environment with deep, fertile soil and abundant water, while the temperatures in northern China are relatively low and unsuitable for pomelo growth. If pomelo is grown in the north, even if the pomelo tree can survive, it

Can lemons be grown in the north? An analysis of growing conditions and methods
Summary Lemons cannot be grown in the north, but potted lemons can be grown there. Lemons have high temperature requirements and need to be grown in an environment that is warm in winter and cool in summer, while winter temperatures in the north are relatively low, which is not good for lemon growth. When growing potted lemons in the north, if

Can vermicompost be used directly to grow grapes?
Summary Vermicompost cannot be used directly to grow grapes; it needs to go through a decomposition process before it can be applied, and during decomposition a large amount of moisture must be maintained for it to ferment completely. Vermicompost after fermentation is very suitable as fertilizer for grapes, and its low cost can save money on buying fertilizer.

Key Points of Shaping and Pruning Techniques for Schisandra chinensis Cultivation
The vines of Schisandra chinensis are soft and cannot stand upright, so they need to attach to a support and twine upward to grow. Therefore, its shaping work includes two tasks: setting up supports and pruning. (I) Setting up supports The growth amount of Schisandra chinensis in the year of planting varies greatly. Under conditions of poor seedling quality and poor management, plant height generally reaches only 50-60 cm, but after stumping pruning, the average growth height in the second year can reach more than 150 cm, and by the third year it can cover the trellis surface. Therefore, supports can generally be set up in the spring of the second year (early to mid-May). Supports can use trellis poles and sun-resistant polyethylene rope. Bamboo poles are often chosen as trellis poles. Bamboo poles are 2.0-2.2 m long, with a top diameter of 1.5-2.0 cm; sun-resistant polyethylene rope with a thickness of 3×15 strands is more suitable, with the upper end fixed to the first iron wire at the top. According to the plant spacing, 1-2 poles per plant. When the plant spacing is less than 50 cm, one pole can be set per plant, placed about 5 cm beside the plant; when greater than 50 cm, two poles per plant, evenly inserted or fixed on both sides of the plant. The part of the bamboo pole entering the soil is best coated with asphalt to extend its service life. The trellis poles are fixed to the three trellis wires with thin iron wire. In a Schisandra chinensis orchard with good seedling quality and management, the plant can reach a growth height of about 2 m in the same year, so supports should be set up in late May of the planting year to facilitate rapid plant growth.</p><p>(II) Shaping</p><p>The purpose of shaping Schisandra chinensis is, through artificial intervention and induction, to make it grow and develop according to the grower's requirements, so as to fully use the trellis space, effectively use light energy, reasonably retain vines, regulate the relationship between vegetative growth and reproductive growth, and cultivate robust and long-lived plants, so that they adapt to climatic conditions and facilitate farming, pest and disease control, pruning, and harvesting operations, thereby achieving the goals of high yield, stable yield, and high quality.</p><p>The tree form commonly used for Schisandra chinensis is a training method with one group or two groups of main vines, that is, each plant retains 1 group or 2 groups of main vines, which are respectively twined on evenly arranged supports. On each support, 1-2 fixed main vines are retained. Lateral vines and fruiting mother branches grow on the main vines. The spacing between each fruiting mother branch is 15-20 cm, evenly distributed. Fruiting branches and vegetative branches grow on the fruiting mother branches, as shown in Figure 5-3. The advantages of this shaping method are that the tree structure is relatively simple, and the shaping and pruning techniques are easy to master; cultivation can be carried out between plants and rows, making weed control convenient; the plant volume and load are small, and the requirements for soil, fertilizer, and water conditions are less strict. However, because the plant is relatively upright, it is prone to forming a situation of strong upper growth and weak lower growth, with the fruiting position moving upward, so control needs to be strengthened.</p><p>Each tree generally needs 3 years to form its tree shape. During the shaping process, special attention should be paid to the selection and retention of main vines. Branches with strong growth vigor, full growth, and plump buds should be selected as main vines. The number of main vines in each group must be strictly controlled. Too many main vines will cause adverse consequences such as weakened tree vigor and chaotic retention of branch groups.</p>

Post-harvest management of peach trees cannot be relaxed; these tasks must be done well
After peach trees bear fruit, they consume a large amount of nutrients, and peach harvest happens to coincide with the rainy season. If technical management can be strengthened in time, it can increase the tree's nutrient accumulation, restore tree vigor as quickly as possible, form good flower buds, and create favorable

Can pig manure be piled up after root digging during the dormant period of sugar mandarins?
Q: May I ask whether pig manure can be piled up after root digging during the dormant period of sugar mandarins? A: From the biological characteristics of the sugar mandarin fruit tree, there is no relatively clear so-called dormant period. What you may understand as the so-called dormant period probably refers to the plant entering the flower bud differentiation stage after the onset of winter, that is

Will pigeon eggs that have been cold for a night still hatch into baby pigeons?
Summary During the incubation of pigeon eggs, the temperature of the eggs should not be allowed to drop. If the eggs are cold for a night, it will have an adverse effect on pigeon incubation, but there is still a possibility that they will hatch. In winter, the pigeon loft needs to be protected from cold and kept warm to avoid drafts, while in summer it needs

What to do if a sow has been unable to deliver a stuck piglet for two days? Includes common handling methods
Abstract Stillborn: For sows that continuously discharge lochia from the body and show signs of labor, a syringe can be connected to an insemination tube to inject saline at a concentration of 1%-3% and a temperature of 36-38°C into the sow's uterine cavity until the saline flows out of the sow's body, then combine with oxytocin.
