In rural orchards and vegetable gardens, there are usually a few castor beans, is there any use in p

The smell emitted by these plants can control pests and insecticides, and it is a pest-repellent plant that protects the environment of the estate from pests and diseases.

This can kill insects, also remove pests and diseases, can protect crops, can repel insects.

This tree has a certain toxicity and can achieve the effect of insect repellent, which can prevent pests and diseases, and can also kill pests.

These trees can be used to kill insects, can prevent pests and diseases in the vegetable garden, which can also increase the production of vegetables, can also make vegetables grow better, and castor seeds can be mashed and soaked in water at any time to kill insects.

It can play a role in preventing mosquitoes, can also prevent some birds from stealing fruits, can play a role in dispersing birds, can also play a role in helping to increase nutrition, and can also play a role in killing pests and diseases.

It has the effect of sterilization, which can eliminate insect pests, also promote the growth of plants, help avoid insects, and can also play a role in guaranteeing that the fruit is protected from damage.

This tree kills pests and diseases and is able to form a natural barrier. This protects fruit trees and vegetables. This also drives away the animals.

Castor is a poisonous plant, there is no animal to gnaw castor, on the contrary, see this poisonous castor, many livestock will walk around, so the villagers use this characteristic of castor, specifically around some vegetable gardens and orchards, planting some castor beans, it can play a barrier role to prevent cattle and sheep, chickens and ducks from entering the gnawing, this method is simple to operate, and quite effective, the castor beans planted also have a certain economic value, the fruit is abundant, you can squeeze oil, someone specially came to buy, Therefore, planting castor beans is a good way to get the best of both worlds and prevent livestock from entering.

Castor itself is toxic, it is also one of the main soil pesticides in rural areas, often people use castor leaves to rub and crush, as a soil pesticide insecticidal use, for many kinds of insect pests have a good effect on elimination, like the rural dry toilet in the past, fly maggots often appear in summer, rural old people love to go to the wild to pick some castor leaves, chopped and thrown into the toilet, there is a good effect of eliminating fly maggots, castor is also the main raw material of soil pesticides, as castor beans in vegetable gardens and orchards around the castor, it can also play a certain role in repelling insects, insect repellent effect.

Plant a few castor beans in a vegetable garden or orchard, one is to use its smell to repel pests such as cabbage worms, cotton bollworms, aphids, etc., and it can also make pests such as beetles that eat castor leaves extinct; Second, you can use castor leaves, castor seeds, etc. to mash at any time and soak in water to kill insects. Because castor beans have a special smell that is very unpleasant, it can ward off insects and can also be used to kill pests and diseases.

Castor oil plant. It often appears in the fields of the countryside, and the elderly will often tell children that these things are poisonous if they are not touched easily, but they can poison some pests.

Castor, once an important oil crop, extracts oil that can be used as a high-quality aviation smooth oil to meet the needs of aviation equipment. In addition, ricin is also an important role of castor, I heard that ricin is hundreds of times more toxic than tetrodotoxin, and blood seals the throat. In addition, castor beans are also a traditional Chinese medicine, and their use is relatively common.

It can kill pests, it can prevent pests and diseases, it can repel insects, this plant is poisonous and can improve the safety of crops.

It can use the smell to remove green worms, can be used to squeeze oil, can be used to cook, has the effect of bruises, and can also reduce swelling and pull out poison.

It's to kill the scarab, which likes to eat those plants. So it's about avoiding threats to orchards and vegetable gardens.

In the rural area of Jiaodong, Axi's hometown, in the 70s of the last century, he heeded the call and indeed planted a lot of castor beans in a collective manner. Ah Xi still remembers the largest castor field, in the north of the village, originally belonged to the barren saline-alkali land, planting any crops do not like to grow, do not want to plant castor beans, but very strong, it can be seen that castor is very adaptable, not afraid of saline-alkali land.

Everyone knows that peasants love the land as much as their lives, especially in that era when they did not have enough to eat, but why did they still respond to the call and plant castor beans in large quantities? The reason is: this is to encourage planting, castor beans are all ** refining castor oil, it is said to be an important industrial oil, aviation and other places are needed, rural people love the country the most, not to mention planting castor beans ** castor beans to pay money, even if you don't give money, it is estimated that you have to plant.

At that time, there was also a wrapper who was responsible for technical guidance and talked about the benefits of planting castor. One of them is castor bark, which is still a good fiber material. So after picking the seeds, the castor stalks were thrown into the river and rubbed, and after the hemp skin was peeled, the villagers used a lot of hemp ropes.

Ah Xi also learned from adults when he was a child, sitting in the yard, soaking hemp skin in a mud basin, and kneading hemp rope on the exposed calves while tidying up.

As for, why is there less planting now?

Needless to say, it was no longer purchased later, castor beans are not top food, castor oil can not be eaten as oil, and castor beans are very toxic, 4 7-year-old children eat castor beans 2 7 grains, it can cause poisoning and death. Adults can kill if they eat 20 pills. Such a dangerous thing, and it can't be exchanged for money, so naturally it won't be planted.

Anyway, this is the reason why Axi's hometown was abandoned in the countryside, and all the crops such as corn and wheat were planted back.

So, what does castor do?

1. Medicinal value.

Castor beans. In rural areas, castor beans are applied as a home remedy, mainly for leaves and roots. Castor beans are mashed and applied externally, which can reduce swelling and pull out poison.

Leaves are decocted and washed externally, which is effective for eczema and itching. Fresh castor leaves are picked directly and thrown into the open toilet to kill maggots and litter.

Castor root, has the effect of dispelling wind and invigorating blood, relieving pain and sedation. Rural remedies have boiled water to drink ** epilepsy, and the effect is said to be good. However, in view of the great toxicity of castor, it is recommended to use it according to the doctor's advice, and you must not use it indiscriminately.

2. Raw materials for papermaking and rayon. What is used here is naturally hemp rod skin.

3. Industrial raw materials.

To make industrial raw materials, the main thing used is castor oil, because of the particularity of castor oil: it is not frozen in -8 -10, and it is not coagulated and denatured in 500 600, so it naturally has an incomparable importance with other oils.

To sum up, it is Axi's analysis of the reasons for the planting of castor beans in the countryside of his hometown, from the promotion of planting to the final disappearance. I wonder if the castor planting in your hometown is the same reason? Are there still castor beans planted now? Feel free to chat in the comment section!

It is because there is no profit after planting such things, and there are many places where such things are not allowed to be planted, and the speed of spreading is particularly fast, and the vitality is particularly tenacious, which will destroy the soil structure.

Because there is no energy to plant, the value is not very high now, and there is not as much profit as before, so there are fewer and fewer people planting.

Because this thing doesn't have much value, people don't have much use for planting this kind of thing, and they don't have much profit.

800-1200 plants per mu.

Before sowing, the seeds should be selected and sun-dried to improve the germination rate of seeds, and the seeds should be sown as early as possible in mid to late April when the average temperature reaches 12-15. If conditions are met, mulching can increase the growth period by about 15 days. Sowing is generally done by artificial point seeding, row spacing of 80-100 cm, 2-3 grains per hole, according to different soil fertility, 800-1200 plants per mu, seeds are sown deep about 6 cm, and the soil is covered and suppressed in time after sowing.

Field management. Check the seedlings and supplement the seedlings: check the castor seedlings in time after the seedlings emerge, check the seedlings and supplement the seedlings, and find that there are missing seedlings to make up the seedlings and transplant them in time. Castor beans are easier to survive when transplanted at the seedling stage, and the transplanting time is best within 3 leaves at the seedling stage.

Seedling setting is carried out when there are 3-4 leaves, and one plant is left in each hole when the seedling is determined. Cultivating, weeding, soil cultivation: Castor is a temperature-loving crop with a deep root system, so early tillage is carried out to raise ground temperature.

Cultivating is generally carried out 3-4 times from seedling emergence to flowering, with a depth of about 10-15 cm.

Fertilization: the application of plantar fertilizer is the key to ensure the yield of castor, castor needs a large amount of fertilizer, according to the determination of every 100 kg of castor seeds need to consume pure nitrogen, phosphorus pentoxide, potassium oxide, so the bottom fertilizer must be applied sufficiently, generally 15 kg of urea or 10 kg of diammonium, 7 kg of potassium sulfate. The first topdressing is at the budding stage of the first main panicle, and 50 kg of ammonium carbonate is generally applied per mu.

The second topdressing was 40 kg of ammonium carbonate per mu at the fourth panicle budding stage. Whole technique: The first time is to leave three stout branches as first-class branches after the main stem buds, and remove all the branches below five leaves.

The second time, about 40 days before the first frost came, all the growth points were removed.

Harvesting standard: 80% of the capsules on the ears are yellow-brown, which can be harvested, and the recovered capsules should be dried in time, threshed, and can be bagged when the moisture drops below 9%.

At present, the vast majority of the crops planted in rural areas are grain crops, vegetables and fruits, fruit trees, etc., which can be directly used and are easy to use; Second, the economic value is high and the profit is good；Third, the vast majority of those who do farm work in the countryside are elderly, and the food crops they grow are sufficient. If castor beans are planted, the main use before the countryside is mainly medicinal value, and there is no machinery and equipment and technology for the production and processing of farmers, and the castor seeds are harmful and cannot be used immediately, so the countryside will plant less. Castor beans also contain ricin, which is toxic and has an insecticidal effect on many agricultural pests.

Castor leaves contain ricin, which is also effective against some agricultural and animal husbandry pests and diseases. For example, one part of dried castor leaves with 5 parts of water, boiling, the actual effect of inhibiting the germination of wheat stalk embroidery pathogen summer spores can achieve 96%; The actual effect of 5 times water immersion solution for wheat cotyledon rust control is 73%. Therefore, in the past, castor beans and castor beans could be used to produce and manufacture soil fertilizers.

Nowadays, although there are many biopesticides, castor beans are natural and organic products. The oil bun after castor beans are pressed with oil is a very good organic fertilizer. And this kind of oil bun, there is also an endotoxin in it, which can be used as feed after destroying the endotoxin through continuous high temperature, and the second senior brother likes it very much.

Castor leaves also have a key primary use, which is that they can be used to raise castor silkworms. The castor silkworm still spins silk and forms cocoons, which are then used for production and processing into silk. Castor silkworm manure is a good organic fertilizer, and can also be used to feed fish.

Silkworm pupae contain crude protein, and the main use is also very large, it is the main food, industrial production, chemical plants, and pharmaceutical raw materials. The stem of castor has bast fibers in the skin, which can be used as fine hemp rope, burlap bags, rayon cloth, and raw materials for the paper industry. There is also polypeptide sugar in the stems of winter, which can be used as a culture medium for cultivating black fungus.

The remaining castor stalks can also be used as a raw material.

One of the most important characteristics of castor is that it is poor tolerant, drought tolerant and salt resistant soil, strong adaptability, rapid growth and development, and general livestock and poultry do not like to eat castor, and it is very easy to grow. The management method can be coarse or refined, and it is a good crop suitable for the scattered land resources of many villages! As we all know, a natural law, that is the law of the jungle, survival of the fittest, some things will be left again, in fact, in addition to the ecological environment standards, there is a more critical element, that is, its economic value, due to the rapid development of social development, many things are substitutes, when there are faster substitutes, it is certainly not very good, the planting of food crops also follows this kind of regularity, farmers and good friends are tired of planting every food crop,That's all about profit, that is, the economic value of the food crop, if the economic value is not good, of course, there will be fewer people planting, and the reason why the castor beans that were commonly used before has faded is also here.

The main reason is that there are fewer and fewer people acquiring now, and there are many other alternatives, and the economic returns are relatively low.

Because you don't make much money growing these things, if it's profitable, there are many people who plant them.

Now the demand for this kind of thing is not particularly high, so there is less planting.

The yield of castor beans per mu is about 300 kilograms, but the yield of advanced cultivation technology in Wudang is more than 1000 kilograms, and with the reduction of oil resources, finding alternative energy sources has become the primary task of countries around the world. Castor oil is a renewable resource, and most of the series of products obtained from petroleum can be obtained from the deep processing of castor oil. Castor oil is considered by relevant experts to be a renewable petroleum resource with great development potential.

The United States selected castor oil as one of the eight strategic materials, and France selected the production technology of castor oil nylon 11 resin as the top state secret. Sesame oil and its deep-processed products nylon 11 resin, 12-hydroxystearic acid are widely used in medicine, aerospace, aviation, military, communications, machinery manufacturing, fine chemicals and other high-tech fields. The world's main importers of castor oil are industrialized countries such as France, the United States, Germany, the United Kingdom and the Netherlands, accounting for 61% of annual consumption.

According to the survey of the castor market at home and abroad, the shortage of castor beans is increasing year by year, and the demand is increasing year by year, becoming the best-selling wonderful product in the market. Global demand for castor oil is expected to reach 1 million tonnes in 2015, equivalent to 2.4 million tonnes of castor oil. The global production of castor oil is only about 600,000 tons, which is a big gap.

There is currently no alternative to castor oil. Underground oil and natural gas resources are gradually decreasing, and oil and gas consumption for transportation and domestic use is increasing rapidly. As a result, the demand for castor oil will increase dramatically.

Therefore, the castor oil in the international market has doubled. If it can enter the deep processing of the series products, its value will be multiplied.

Due to the shortage of castor raw materials, most enterprises are in a state of suspension or semi-suspension, and many enterprises need to import large quantities of castor oil from India. Therefore, it is not only difficult to sell ramie planting, but it is also essential to vigorously develop ramie cultivation. Compared with food crops, castor beans are easy to grow, with less investment and high efficiency.

In addition, castor beans are adaptable, barren, and have strong disease resistance, and can be planted in the field, in front of the house, and behind the house, so it is easy to master the cultivation technique. At present, Malaysia's castor oil planting industry lags behind other Southeast Asian countries, and there is a shortage of castor oil planting and development enterprises and processing refineries. However, Malaysia's geographical and climatic environment is very suitable for castor planting, so I believe that the future prospects and advantages of castor cultivation in Malaysia are unlimited.
