How to harvest hydroponic plants

The harvest season of hydroponic plants varies from region to region. Zhejiang is from April to May, Guangdong and Fujian are from March to April, and Lianyungang is suitable from May to mid-June. Naturally growing hydroponic plants can be harvested after the spring tide. In the sea area with good growth, one person can harvest 100-150kg hydroponic plants a day. Raft aquaculture can be collected together with the rope, fully washed, and then hydroponic plants are removed from the rope and dried in the sun or salt. For consumption or as raw materials.

We must know more about hydroponic plants now, so the current situation of hydroponic plant culture is very ideal, and most of the harvested hydroponic plants are artificial, which shows that the amount of labor is still very large. That's all for today. Thank you for your reading.

What kind of Euryale seeds do hydroponic plants have?

Euryale seed, commonly known as chicken head rice in the north, is also known as wild goose beak fruit, aconite, thorn lotus seed, chicken head fruit, Su Huang, yellow fruit, and so on. It is the dry mature seed kernel of the aquatic plant Euryale, which is harvested at the end of autumn every year. Euryale seed is a kind of traditional Chinese medicine, which has the effects of tonifying kidney and essence, tonifying spleen and stopping diarrhea, removing dampness and stopping belt.

Water chestnut

Water chestnut, also known as water chestnut, is the fruit of annual herbaceous plant, widely planted in the provinces of southern China, water chestnut is a kind of fruit food, because it is difficult to store, it is mostly made into water chestnut powder and sold all over the country. Water chestnut powder is rich in starch, which can be converted into sugar in the body.

Sargassum fusiforme

Sargassum fusiforme is a good marine algae. Sargassum fusiforme generally grows on the rocks along the sea, but we all know that things in the water are inevitably wet, and it is relatively difficult to transport and preserve them. So the smart businessman thought of drying Sargassum fusiforme before it was transported and put on the shelves, so dried Sargassum fusiforme is also very popular.

These are the varieties of hydroponic plants with relatively high yield in our country. The yield of hydroponic plants is slightly less than that of aquatic plants, because harvesting is very difficult, so how can hydroponic plants be harvested?

Efficacy and function of peppermint Culture methods of peppermint

Culture method of peppermint

The best propagation time: the suitable time for seed sowing is from March to April in spring and from September to October in autumn.

Rhizome propagation: it can be planted in spring or before winter, mostly in late March to early April, and around late October before winter.

The best growing soil: peppermint is not very strict on the soil, except for sand, excessive viscosity, excessive pH and low-lying poor drainage soil, the general soil can be planted, sandy loam, alluvial soil is better. The suitable pH value of soil is 6-7.5.

Growth humidity requirements: peppermint has a strong ability to adapt to environmental conditions, can grow in areas below 2100 meters above sea level, born in waterside tidal wetlands, up to 3500 meters above sea level.

The best growth temperature: peppermint has strong adaptability to temperature, its rhizome survives the winter, and can withstand-15 ℃ low temperature. The optimum temperature for its growth is 25 ℃ ~ 30 ℃. The growth was slow when the temperature was below 15 ℃ and accelerated when the temperature was higher than 20 ℃. At 20 ℃ ~ 30 ℃, as long as water and fertilizer are suitable, the higher the temperature, the faster the growth.

The best growth light: peppermint is a long-day crop, sexual like the sun.

To apply fertilizer:

The cultivation of peppermint needs fertilizer, and peppermint likes fertilizer, which is topdressing once a month during its growth period. Nitrogen fertilizer is the main fertilizer, and phosphorus and potassium fertilizer can be applied properly. If the branches and leaves need to be harvested during the growth period, topdressing should be carried out during the harvest to promote the plant to restore a good plant shape.

Watering essentials:

The main results are as follows: (1) more water is needed in the early and middle stages of peppermint, especially in the early stage of growth, the root system has not yet been formed and needs more water, generally watering for about 15 days, and 4 to 5 times from seedling emergence to harvest. After sealing, it should be irrigated gently to avoid excessive growth of stems and leaves, lodging and shedding of the lower leaves. The water will be cut off 20 to 25 days before harvest.

(2) peppermint likes the moist soil environment and is more resistant to moisture, especially during the growth period, but the amount of water should not be too large, and waterlogging is strictly prohibited. Usually when watering, we should maintain the habit of "no dry, no watering, watering thoroughly". If you use Amoy rice water, it will be more beneficial to the growth of mint; in winter, you should reduce the number of watering and the amount of water.

Pruning essentials: those who raise peppermint must be trimmed regularly. Lao Miao can be cut off if there is no clear fragrance.

Pot soil replacement: when turning the basin and changing soil every spring, a large number of plants can be isolated. Keep the basin soil wet at ordinary times.

Disease prevention and control:

1. Black shank disease. The main disease of mint is black shank, which occurs at the seedling stage. The symptoms are that the base of the stem shrinks and sinks, blackens and rotts, and the plant loses and wilts. For prevention and treatment, 70% chlorothalonil or 40% carbendazim 100g-150g can be used and sprayed with water.

2. Mint rust. It is easy to occur from May to July. 1000-1500 times liquid blade spray is used.

3. Spot blight. It occurs from May to October, and 65% of Dysen zinc 500 times solution is sprayed at the initial stage of the disease, which can be controlled once a week.

Peppermint hydroponics:

1. Peppermint likes light and water, so put it where there is enough light, and you can't stay in the shade where you can't see the sun all the time. In this way, it is difficult to produce photosynthesis, take root less and grow leaves.

2. You don't have to change the water every day. I usually change it only once a week. If there is less water in the bottle, I will add a little more, but don't fill it up. I will drop some nutrient solution into the water so that I can provide mint nutrition.

3, peppermint likes water, so I will sprinkle the leaves twice a day, with a small spray can, in fact, the amount of water is not much, but because it is foggy, it is fully absorbed.

4. Although it is so meticulous, the leaves will turn black. I usually remove the black leaves after I see them. Vanilla plants are not afraid to pick, but become more and more prosperous. Black leaves may also be contagious, so it is better to remove them as soon as possible.

5. Wash the roots while changing the water, remove some rotten leaves and keep the bottle and whole mint clean.

6. Peppermint grows very fast, both in water culture and soil culture, so it can be branched at the right time, that is, cut off one branch and divide it into two branches to continue hydroponic or soil culture.

Experience of cultivating peppermint

Mint likes a warm and humid environment, and the frost-free period should be more than 200 days.

The requirement of soil is not strict, except for heavy alkaline land, heavy clayey land and sandy land, all can be planted, but it is better to use fertile loam and sandy loam. Sunlight plays an important role in increasing the content of menthol and peppermint oil, especially in the blooming period of pregnant buds, there should be enough sunlight, so mint should not be planted in shady places.

Long sunshine plants of the genus mint. Sexual preference for adequate sunshine, bud flowering requires sufficient sunshine and dry weather, which can increase oil content and brain capacity.

If there are too many Rain Water in the later stage, it is easy to grow, the leaves are thin, the lower part of the plant is easy to fall leaves, and there are many diseases.

Sexual preference for neutral soil, PH 6.5-7.5 sandy loam, loam and humus soil can be planted.

Peppermint likes fertilizer, especially nitrogen fertilizer, avoid continuous cropping. The sunshine is long, which can promote the flowering of mint.
