How to carry out pest control when planting traditional Chinese medicine safflower?

Pesticides can be sprayed on pests and diseases every day, which can be effective.

You can spray some insecticides, which can kill a lot of pests and diseases, and you should also expose them to more sunlight, so that you can also kill a lot of bacteria through high temperature, and water them frequently.

When planting safflower, spray some pesticides around the soil first, and then spray pesticides according to the growth cycle of safflower.

Most of us have watched court dramas, so we should be familiar with safflower. But taking safflower during pregnancy or prolonged exposure to safflower can cause miscarriage. In fact, safflower has another effect.

For example, blood circulation, beauty and beauty, detoxification and swelling, blood pressure and lipid reduction, etc., at present, many drugs contain safflower ingredients, and the demand is relatively large, and the cultivation of safflower is more. Soil safflower is adaptable to the environment and can be grown as long as there is land, but be aware that if you want a high yield, you need to have soil requirements.

It is best to choose plots with strong soil clarity and more nutrients. The land should not be relatively flat and sunken, as close as possible to a place with water for easy irrigation, and finally the soil should be as sandy as possible. The right sowing time has a great impact on the yield of peach blossoms, but the safflower sowing time should be planted according to different regions.

Due to the difference between the climate in the south and the north of China, it is best to sow seeds in the south of China from mid-October to the first month of November. Moreover, in the north and south, it is better to sow seeds in spring in March. The temperature during these two periods is basically around 15 to 25 degrees, which is very suitable for safflower germination and growth.

Density There may be some variation in planting density due to different sowing methods. For example, the distance between a tree is 20 centimeters, the distance between each row is 40 centimeters, and in the case of blood seeding, only the distance between each tree needs to be considered. Usually 25-30 cm, at the same time we can divide the interval according to the fertility of the soil, which helps in the field management and later collection of safflower.

Modification of safflower requires special attention to fertilization during the growth process. First of all, the basic fertilizer should be mixed and sprayed with farm fertilizer, urea, phosphate fertilizer, zinc fertilizer, and potassium fertilizer, and then turned over the soil and buried deeply.

During the development period of safflower, we should do at least three autumn rains. The amount used at each additional charge shall not exceed 500 kg. Among them, the first fertilizer is dug up a week after the safflower sapling, the second is about 30 cm long for the safflower sapling, the third is about to enter the flowering period, and the fourth is after harvesting, and the fertilizer types are almost the same every time, all of which are potassium, phosphate and zinc fertilizers.

When planting safflower, you should choose fertile soil, and make the soil more fluffy and absorbent, you can add some farm fertilizer when turning the ground, you can also add some superphosphate, if it is in the cold area is generally sown in spring, keep a certain distance, not too tight, after sowing after covering the soil and watering some water, about half a month or so can emerge seedlings, generally in the seedlings grow to about 7 cm can be carried out seedlings, at this time the weak ones are pulled out, It is also necessary to scientifically prevent pests and diseases.

We must pay attention to the temperature, pay attention to the amount of watering, and pay attention to the circulation of air, which are very important, and we must choose the right varieties for planting and manage them according to scientific methods, which must be understood in advance.

The aspects that need to be paid attention to when planting safflower are to ensure the temperature and humidity of the growth of safflower, to ensure that the soil nutrients of safflower are sufficient, to ensure the growth environment of safflower, and to ensure the growth state of safflower. When cultivating and managing the safflower, it is necessary to fertilize the soil, so as to ensure the nutrients of the soil, and often observe the state of the safflower when planting, and also often fertilize the safflower, and then timely repel insects and insect pests to the safflower, which are the cultivation and management methods of planting safflower.

When the seedlings grow to 6-7 cm, the seedlings should be thinned, the weak seedlings will be removed, and the strong seedlings will be left, generally 2-3 strong seedlings will be left in each hole, and if there is a lack of seedlings, the seedlings should be replenished in time. When the seedlings grow to 4-5 leaves, they should be watered with thin human manure once, and when topdressing, they should be applied from the side of the roots to avoid the seedlings lodging. Before and after the sting, it is the second fertilizer, and 500-600 kg of human manure and urine fertilizer are applied per mu, and it is matched after application to avoid the lodging of flower buds.

It should be watered and fertilized in a timely manner, and sandy soil should also be selected, and water and fertilizer management should also be strengthened, and it is also necessary to remove pests regularly, spray some pesticides in time, and should also do a good job of drainage, and also ensure that the light is sufficient and the temperature is appropriate.

It is cultivated in sandy loam soils with mild climate, abundant sunshine, high and dry terrain, medium fertility, good drainage and loose texture. Choose good quality seeds for planting, and then choose the land to prepare the land, and after sowing, you should also water and fertilize in time to prevent pests and diseases.

1.Rust: It is more harmful to the back of the leaf.

The control methods are: after picking flowers, pick up the residual plants and burn the diseased leaves; Spray 97% sodium dirust 300 400 times solution, once every 10 days, 2 3 times in a row. Crop rotation is carried out to prevent and control pathogenic bacteria in the soil.

2.Root rot: Infected by root rot bacteria, it can occur in the whole growth stage, especially in the seedling stage and flowering stage.

After the onset of the disease, the plant wilts, is light yellow in color, and finally dies. Prevention and control methods: If the diseased plants are found, they should be uprooted and burned in time to prevent infection to the surrounding plants, sprinkle some quicklime or fast lands in the holes of the diseased plants to kill the rhizosphere nematodes, and water the diseased plants with 50% of the 1000 times of Tobujin Honglu.

3.Black spot disease: The pathogen is a semi-known fungus, which occurs in April and May, and the leaves are oval-shaped lesions with concentric ring patterns after damage.

Prevention and control methods: remove diseased branches and residual leaves, and destroy them in a centralized manner; crop rotation with gramineous crops; After rain, ditches should be opened in time to reduce soil moisture. At the onset of the disease, it can be sprayed with 70% mancozeb 600 800 times liquid, once every 7 days, 2 3 times in a row.

4.Anthracnose: It is a disease in the late stage of safflower production, mainly affecting branches, stems and buds.

Control methods: select disease-resistant varieties; crop rotation with crops of the family Gramineae; 5 kg of seeds were mixed with 25 grams of 30% phenanthrene quinone, and sown after mixing; Spray with 70% mancozeb 600 800 times solution, once every 10 days, 2 3 times in a row. Attention should be paid to removing stagnant water, reducing soil moisture, and inhibiting the spread of pathogenic bacteria.

5.Heartworm is extremely harmful to the inflorescence, once the insect burrows into the inflorescence, the flower dies, which seriously affects the yield.

Control method: Apply methamidophos foliar spray 2-3 times in the budding stage to kill the borer.

During the occurrence period of round rock aphids, dimethoate can be sprayed 2 3 times with 1000 times to kill aphids.

It should be planted in March and April every year, some chemical fertilizers should be used, and it should be watered frequently, and it should be careful about pests and diseases, and it should be aware of the sun's light.

It should be planted in March and April every year, the right soil should be chosen, fertilizers should be chosen, and frequent watering should be the best way to plant the plant.

Generally, planting is carried out in spring, and it is necessary to pay attention to the temperature of planting, and at the same time, we should also choose a good environment, control the temperature well, and pay attention to the selection of varieties.

A bouquet of red flowers, bright and beautiful, but only known to be beautiful. So how should a bouquet of safflower control pests and diseases? Leaf spot and downy mildew often occur, and 65% zeb wettable powder can be sprayed 500 times.

10% permethrin EC 2000 times can be sprayed with common pests such as Spodoptera exigua, short-shouldered star beetle, whitefly, and aphid. Due to high humidity, high temperature, serious shading, and unventilated leaves, measures should be taken in time. The pests are mainly leaky red spiders under dry and hot conditions, which can be killed by adding 1000-1500 times of dicofol to water.

Adding 1000 times dimethoate water can kill aphids. Whiteflies can be killed by adding 1000 times more water to the enemy, then adding a small amount of Tween, shaking, spraying. Mold blight is a devastating disease of red flower bouquets that mainly damages the stems, branches, and leaves of flowers.

The incidence is high, the development is fast, and it can lead to the death of a large number of flowers. After the plant is infected, at the beginning of the infestation, watery, dark green, irregular spots appear on the infected part of the stem, which gradually expand and spread upward. Later lesions are dark brown with inconspicuous margins.

The disease progresses quickly and soon spreads to the middle, and even plaques appear on the top. When the silver is heavy, the stem of the whole plant turns black. Leaf damage mostly occurs at the leaf margin and base, and the leaf wilts after petiole injury.

When it is damp, white mold grows. Prevention and control methods: mainly humidity control, should not be placed or planted too densely.

Pay attention to drainage, potting, and ventilation in the high temperature and humidity season. When watering, prevent the soil from splashing on the leaves. Less watering, less morbidity conditions.

When diseased plants are found, they should be uprooted and burned in time. At the same time, 5g-10g of 70% pentachloronitrobenzene powder was applied to the plants every day to disinfect the soil and prevent its spread. Spray 700 times of chlorothalonil wettable powder or 600 times of zeb wettable powder at the beginning of the disease and spray it in the soil under the plant.

Here are some of the common pests and diseases that Xiaoyisou has compiled for you. If there is any omission, you can raise it. We will update it in a timely manner and hope to bring you some help.

Safflower nickname Super Safflower is a chrysanthemum and safflower plant, its flowers can be used medicinally, with the effect of blood circulation and blood stasis, swelling and pain relief, mainly used for dysmenorrhea, menopause, uterine congestion, camel injury and other diseases. In addition to its strong medicinal value, it is also a natural pigment and dye, and is an important industrial raw material with significant economic benefits. Safflower is cultivated all over China, let's take a look at its planting method.

Safflower cultivation method Safflower prefers arid and fertile plants, adapts to poor soils, and avoids growing in damp puddles.

So when planting, choose a field or wasteland to plant. The best crops are soybeans, winter melons, taro, etc. After the harvest of the previous crop, the plot was turned over and raked finely, the soil was loose and the drainage was good.

When ploughing the ground, you can add 1000 kg of Wudang rotten farm fertilizer and 15 kg of calcium phosphate. Sow. The sowing of safflower is not determined, and spring, autumn, and winter sowing can be selected according to local climatic conditions.

Generally speaking, Jiangsu and other places are broadcast in winter, Shandong is broadcast in autumn, and Xinjiang and the cold areas of Northeast China are broadcast in spring.

On-site management of seedlings to 6-7 cm when the seedlings grow to 6-7 cm, remove weak seedlings, leave strong seedlings, generally leave 2-3 strong seedlings of blood sugar, if there is a shortage of seedbeds, the seedbeds should be replenished in time. When the sapling reaches 4-5 leaves, it should be given a thin manure and sprayed next to the roots during the autumn rain to prevent the sapling from falling. Before and after the chips is the second fertilizer, add 500 600 kg of manure per mu, and mix it after application to prevent the flower buds from falling.

Safflower cultivation method. The most important thing to pay attention to when sleeping with safflower is to strictly control the water. In other words, if there is moisture, it is enough to keep it from wilting.

Pests and diseases safflower is attacked by various pests and diseases in the process of growth, and common diseases include root rot, rust, black spot, anthracnose, etc. The insect pests are mainly tigers, crickets, needleworms, earthworms, earthworms, etc. They all affect the growth of plants, and in serious cases, cause plant death, which is a huge harm, and it is necessary to do a good job in pest control.

The requirements for the soil are not particularly strict, but it is also more like some barren soil, but you can't choose a more humid soil, don't water too much when watering, sowing is generally carried out in winter, colder places, you can sow in spring, there are often some pests and diseases, so you must pay attention to spraying pesticides, the requirements for the soil are not strict at all, what kind of soil can survive.

Generally, there is a way to select land and prepare the land, and in the process of planting, you can also choose autumn seeds, and then you can also choose spring seeds, and then you can also choose winter sowing in these places in Zhejiang, first of all, you must choose dry soil, and the soil must be particularly loose, and the drainage must be good.

There are three planting methods for planting traditional Chinese medicine safflower, which are monocropping, intercropping, and film mulching. Safflower has very high requirements for soil, for example, the soil for planting safflower must be soft, the nutrients must be sufficient, and the soil must be made holes when planting, and the soil must be very moist, these are the requirements of safflower for soil.

(1) Safflower long-whiskered aphid: Wingless viviparous aphids gather on the young shoots of safflower to absorb the juice, causing the leaves to shrink and blister. Generally, the damage is reduced during the rainy season and aggravated during the drought. The control method is: when aphids are found, they can be sprayed with 40% dimethoate 1500 2000 times.

2) Leaf miner flies are harmful to leaves, and are generally more harmful before flowering. The control method is: spray 40% dimethoate 1500 2000 times liquid at the beginning of May.

In addition, ground tigers, needleworms, grubs, mole crickets, etc. are also common pests, causing wounds on the surface of the plant at the safflower seedling stage, or biting off the whole plant and making it die.

Dioscoreae is a plant of the family Dioscaceae, which is used as a medicine with rhizomes. It is distributed in Northeast China, North China, Shandong, Henan, Anhui, northern Zhejiang, Jiangxi (Lushan), Shaanxi (north of Qinling), Gansu, Ningxia, southern Qinghai and northwest Sichuan.
