Zanthoxylum pepper tree. How many times do you have to inject anthers, when should you apply pestici

Generally, it is enough to take the flower booster about three times a year.

Expansion: Sichuan pepper aphids.

How to prevent flooding?

Causes The occurrence of aphids is mainly related to the environment, that is, when the soil is dry, the temperature is about 20, and the humidity is below 60%, the aphid damage is high; Secondly, the abundance of aphids is also related to the lack of natural predators, such as the seven-star ladybug.

The lack of natural predators such as aphid cocoon wasps is also the reason for the infestation of aphids. Prevention and control methods.

Agricultural control: use summer pruning to prune off the infested parts and branches with insect eggs. At the same time, combined with topping, budding, remove sporadic new shoots, and interrupt the food chain.

to reduce the source of insects.

Protection of natural enemies: Seven-star ladybugs are the natural enemies of pepper aphids, and growers can intercrop some crops to attract seven-star ladybugs and aphid-eating flies to settle down, and can also artificially stocking seven-star ladybugs and lacewings.

Natural enemies such as aphid cocoons and bees come to the pepper garden to prevent and control aphids, and physical methods such as yellow plates can also be used to trap pepper aphids.

Drug control: 25 imidaclopat emulsion 2000 times, or 50 aphid net emulsion 4000 times can be used for drug control. The number of spraying is generally 2 to 3 times, and it can be carried out in the morning or afternoon on a sunny day.

Sichuan pepper also has pests and diseases, which need to be sprayed. Fight according to pests throughout the year:

Longicorn. Appearing after the beginning of autumn, the larvae eat the branches, and in severe cases, the whole plant dies. Prevention and control methods: When harvesting pepper in autumn, the insect tips are completely cut and burned or killed with wire hooks, and then the cotton is dipped in kerosene or Bataan powder mixture to plug the insect holes;

Butterflies. Adults lay eggs on the back of young shoots or leaves, harming the leaves and making them jagged. Prevention and control methods: pay attention to killing pupae when pruning in winter, culling adults in summer, and spraying aluminum worm acid on plants to kill larvae;

Aphids. Mainly harms leaves. The control methods are: in mid and late October, remove weeds in the ground, tree holes, and stone crevices, eliminate overwintering places, and sprinkle plants with 1500 times dimethoate emulsion in mid-April every year;

Leaf rust. It mainly harms the leaves, and is easy to develop in the summer and autumn of high humidity, and the face of the pepper leaves is round and pale yellow lesions at the beginning of the disease, and then the color of the lesions gradually deepens to yellow-brown and there are powdery orange-red spores. Prevention and control methods.

6 In August, spray 1 2 degrees of stone sulfur mixture or 1000 times liquid methyl tobuzin. In winter, combined with pruning, the fallen leaves and weeds under the canopy will be eradicated and burned, and at the same time, 2 3 degrees of stone sulfur mixture will be sprayed;

Root rot. After the adult pepper tree is infected, the underground roots are edematous, the root bark is easy to fall off, and there is a peculiar smell. Prevention and control methods: The nursery should choose sandy land with good drainage, and the seedbed should be made high, and attention should be paid to drainage. Do not raise seedlings in soil with root rot.

With the development of science and technology and social progress, many people are now basically mechanically integrated when planting crops. However, there are some peasant uncles who still love labor and still insist on cultivating them by themselves. Sichuan pepper is one of the foods that people use to season in their daily life, and some foods must be seasoned when stir-frying.

In fact, planting pepper is very simple, but we should also pay attention to certain ways and methods. Spring pepper tree, what medicine should be used? <>

First, the planting method of Zanthoxylum pepper First of all, in the planting of Zanthoxylum, we must choose seeds with a relatively full head, which will improve the germination rate of Zanthoxylum. And when you buy the pepper seeds, you should also soak them in warm water for a day, which will also greatly increase the germination rate of the pepper. And when the pepper does not germinate, the water requirement is very large, we should also water the pepper all the time, and observe the growth of the pepper.

The farmer can also let the people in his family pay attention to its growth when they are free, and then make adjustments. <>

Second, spraying pesticides but it is inevitable that some pests and diseases will be attacked when planting, and it is necessary to spray certain pesticides at this time. However, in the process of spraying, we must pay attention to the appropriate amount and not use excessive pesticides, otherwise it may also have a negative impact on our own growth. And if you want to plant green and healthy peppercorns, you can use biological control, although this control method is more time-consuming and labor-intensive, but our crops are planted very healthily.

3. Observe the growth and think that the pepper has not fully grown to maturity, and the people in the family should also pay attention to the growth of the pepper tree at all times, and if you find something wrong, you must immediately take measures to change the status quo. Therefore, we must water the pepper tree more in our usual time, so that the pepper will grow bigger and have more juice.

Try to inject some sterilizing drugs, because in this way you can increase the yield of peppercorns, and it will also avoid problems with peppercorns in the later stage.

When the pepper tree is sick in spring, you should go to spray some wettable zebsen powder, and you can also spray Bordeaux liquid.

If there is no problem with the pepper tree, there is no need to spray pesticides, and pesticides have an impact on the quality of the pepper tree.

Organophosphorus pesticides should be used, because this pesticide can kill a lot of pests and reduce pests in pepper trees.

Summary. In spring, pests such as Zanthoxylum bungeanum scale insects, narrow gilding insects, and Zanthoxylum bungeanum leafminer jumping beetles began to move from the wintering sites one after another, and the damage intensified with the growth and development of Zanthoxylum bungeanum trees. Therefore, it is necessary to strengthen the prevention and control of spring pepper insect pests.

Before budding, the whole tree is sprayed with 3-5 degrees of Baumé sulfur mixture. Before germination, spraying with higher concentrations can reduce the base of a variety of pests and diseases, reduce the annual medication, reduce costs, and have significant effects. At the same time, it is necessary to prune the branches with serious diseases and insect infestations, and bury them deeply or burn them.

Prevent the further spread and spread of pests and diseases.

Before germination, spraying with higher concentrations can reduce the base of a variety of pests and diseases, reduce the annual medication, reduce costs, and have significant effects. At the same time, it is necessary to cut off the heavy branches of diseases and insect pests, and bury them deeply or burn them. Prevent the further spread and spread of pests and diseases.

I'm asking what medicine I can take now, it's flowering time.

OK. What kind of medicine.

There is no disease during the flowering period, and the insect pest situation is not skin and late need to be medicated. Zanthoxylum pepper is prone to aphid damage, and imidacloprid can be sprayed when found, and lead plum can be sprayed with potassium dihydrogen phosphate to avoid yield reduction. In addition, potassium dihydrogen phosphate fertilizer can be sprayed appropriately before flowering, and sufficient nutrients can promote better flowering and increase yield.
