Vanilla is an important ingredient of traditional medicine all over the world, which provides most of the medicinal materials that can be used to treat diseases. However, due to population growth and urban expansion, the natural environment for plant growth has been destroyed, coupled with the rise of chemical pharmaceuticals, the use of vanilla plants has gradually declined in modern times.

So, how to grow vanilla? The cultivation techniques are as follows:

1. Species selection

There are many plants that can be used as vanilla, but the most commonly used species are about 10 to 20, some of which are unacceptable to Chinese people, such as Dioscorea nigra, some are not suitable for the climate of Taiwan, such as Angelica sinensis, some of them are not strong in fragrance, and are often used as cosmetology, such as aloe vera. Therefore, choosing cultivated plants according to purpose and understanding its characteristics is the first step to success. You can go to the flower market to buy the species you want to cultivate, buy them back and increase the number with asexual cuttings or ramets, or buy seeds for cultivation.

2. Planting environment

This project includes the right planting place or season. Before you buy vanilla and come back to grow it, you need to know where you want to plant it and whether you have a garden at home. What are the sunshine conditions? Is the soil texture or drainage good or not? Do you want to plant it in a flowerpot or can you plant it directly on the ground? All these should be understood first, and then the species of vanilla to be cultivated should be selected by these conditions. even if you do not understand the characteristics of this species, you can ask the seller to help you choose or give you some advice. Some annual or biennial species will die after flowering, so they must carefully choose the right season to grow. Because most of these herbs are native to high latitudes, under Taiwan's climatic conditions, the cool winter climate is more favorable for growth. This is also the place to know first.

Miniature potted flowers are available for home use and viewing. The front row is rosemary, the second row is two different varieties of lavender, and the back row is thyme, vanilla and lemon basil from left to right.

Some kinds of thick leaves should not be watered too much, moderate drying is conducive to plant development, harvest or pruning, do not cut too much at a time so as not to stimulate too big new buds to grow and die. In the period of rapid growth, using some organic fertilizer on the soil surface, the fertilizer infiltrated into the root during watering is conducive to good growth and development. As long as you pay attention to its growth at any time, everyone can try to plant it at home to increase the interest of life.

Should be equipped with micro-spraying or tap watering facilities. Choose and buy flowerpots of appropriate size, you can choose plastic flowerpots, mud pots or wooden pots, especially valuable varieties can also choose purple sand pots and colored glaze ceramic pots, potted leeks can choose foam boxes, but mud pots should be covered with a plastic pot when they are sold. The following principles should be followed in the selection of matrix, fertilizers and pesticides.

1 the matrix used must be cleaned and thoroughly disinfected. Comprehensive nutrition, no diseases and insect pests. Generally choose peat, vermiculite, perlite, mushroom waste and clean river sand as the matrix.

(2) try not to use chemical fertilizer as far as possible, and use more organic fertilizer such as hemp residue and peanut cake. It can also be made with fermented bacteria and fully mature organic fertilizer with cow and sheep manure as the main raw material.

Allow the use of certain microorganisms, such as rhizobia, photosynthetic bacteria and phosphorus-solubilizing bacteria, to promote the full utilization of nutrients in vegetables through the activities of these beneficial bacteria.

(4) the use of chemical pesticides is not allowed, and plant and mineral biological pesticides are allowed to control diseases and insect pests.

Key points of cultivation techniques of potted vegetables

Arrange the suitable sowing time according to the length of the growth period and consumer demand to arrange the sowing and planting date, so that the planted varieties can be sold in holidays and tourist seasons.

At this stage, the relevant departments and enterprises are lack of familiarity with the significance and role of vegetable distribution, and are not enthusiastic about carrying out or accepting vegetable distribution. As far as the whole society is concerned, it is still vague to be familiar with the development prospect of vegetable distribution.

Adjusting the appropriate temperature, light and humidity and leafy vegetables requires different temperature and humidity. It should be planted separately and managed according to different temperature, humidity and light.

Due to the late start of the development of logistics and distribution in China, the education in logistics and distribution is still quite backward, which has become a major obstacle to the development of vegetable distribution.

Timely pruning vegetables requires not only good growth, but also beauty and artistry, dwarf crops should be pruned in time to remove yellow leaves, tomatoes, melons and fruits should be made of bamboo or steel bars to build frames of various shapes. To make it climb and grow.

Fertilizer and water management should scientifically use tasteless organic fertilizer, timely watering and water control, so that its root system is developed, the growth is strong, the result is good, the most important thing is that there are no side effects on the body, pure natural green.

Control of Diseases and insect pests of potted vegetables

1. Catch bugs. It's primitive but effective. Always pay attention to the front and back of the vegetable leaves and the surrounding soil for signs of pests. two。 Quarantine. As soon as you see the branches and leaves that are infected and eaten by diseases and insect pests, you should remove them immediately and throw them for composting. Vegetables that suffer too much damage should be uprooted and thrown for composting.

3. Homemade natural insecticides. There are many simple and effective recipes. An editor of a science magazine once introduced such a method: "when my vegetable garden was suffering from insect pests, I found that some plants around the garden were safe and sound." I picked the branches and leaves of some of these plants, put them in a blender and mixed them with the same amount of water to make a solution. I sprayed the vegetables in the garden with this solution, and it worked very well. " This is because plants that are not affected by pests must contain some kind of disease-resistant and insect-repellent substance. In addition, asparagus juice can kill nematodes that harm tomatoes. Garlic also has a good germicidal and insect repellent effect, which can be ground into powder or squeezed juice to spray on vegetables and seeds. Horseradish also has a strong ability to kill bacteria and deworms, as well as purify the soil. Orange peel, pepper, garlic, mint, marigold, sage, rosemary, salvia and other plants can be used to make insect repellents.

4. Plough the land. Can control ground tiger, cotton bollworm, leafhopper, aphid, mole cricket and other pests. These pests like to lay their eggs on crop stalks or in the soil after harvest in summer and autumn. Therefore, ploughing the land again after autumn harvest and burying the residual stalks of crops in the soil can prevent pests from laying eggs on it. Ploughing the land again before planting in spring will kill most of the remaining pests. The depth of ploughing must be at least 15 centimeters. In this way, you can dig up the eggs, pupae and larvae of insect pests hiding in the ground and let the hot sun, hot wind and natural enemies wipe them out. In our grandparents' time, it was common for egrets and other beneficial birds to follow farmers' ploughs and dig up worms to eat. Nowadays, egrets are seldom seen. However, when ploughing, if you can catch a few chickens and follow behind to eat bugs, it will also have a good effect.

5. Use a protective case to protect the seedlings. Wrap it on the stem of the seedling with brown hard paper, insert it into the soil and expose it to the ground about 3 cm, which can effectively prevent the tiger from biting off the seedling. This method can also be used to deal with cotton bollworm. 6. Sprinkle the flour. In the early morning, sprinkle some flour on cabbage or cabbage leaves while the dew is not dry. Near noon, you will see a fat cabbage worm struggling in the batter and dying in the sun.

7. Ask the beneficial worm to help. Insects such as mantis, seven-star lady beetles, parasitic wasps and walking insects can help us eliminate many pests, and we can find some ways to attract them.

8. Think of some ways to attract birds to help catch pests. 9. Make a trap. This method can be used to deal with earwig. Take four 30-centimeter-long bamboo tubes, paint them green, dry them and tie them up with nylon rope and place them under a fence tree or other haunted places. A few days later, in the early morning, shake the cymbals in the bamboo tube into boiling water or gasoline to eliminate.

10. Flush with water. Spider mites can be washed down from vegetable leaves by spraying water with a kettle. Under normal circumstances, they will not go back when they are washed behind. This method can also be used to deal with aphids that harm roses.

11. Scatter plant ash. Sprinkling a circle of plant ash or limestone powder around vegetables can also protect vegetables from ground tigers. But be careful not to scatter ash on the vegetable leaves.

twelve。 Putting a bowl of beer next to the plant is said to lure snails and slugs into drowning. You can also sprinkle a circle of coarse sand, cinder or limestone powder around the vegetable bed to protect vegetables from snails and slugs.
