My aunt likes me to grow vegetables. She is a farmer who has grown vegetables for decades. After moving to Shenzhen, she grew vegetables on the top of the building, and the vegetables also looked good. But the “knowledge” she accidentally disclosed made me sweat. She said that she deliberately dug the edge of the garbage dump because the black water from the garbage would make the soil particularly fertile. In Shenzhen, there was no such thing as garbage classification. A small battery could pollute one cubic meter of soil. Not to mention the soil on the edge of unsorted rubbish, who knows what harm it contains?

Many people, including me, driveWhen planting vegetables, the focus is on the soil in the green belt of the community. I strongly advise everyone that this method is not advisable. The plots are often killed, and the problem of pesticide residues has not been considered. It’s hard to say if the soil is safe when the soil is taken back.

Many people buy soil from the Internet. I have heard a news from a professional that scares me later: some bad businesses make contaminated garbage or sludge into nutritious soil for sale at a low price. Therefore, when buying online, you must also be careful and try to buy soil from reliable merchants, and don’t try to be cheap. Poor nutrient soil, from light to bad vegetables, to poisonous vegetables, which runs counter to our original idea.

In China, there are many sayings about soil. What are the characteristics of the soil in your area? Picture | Web

My suggestion

Foodies who have budgets and are afraid of trouble can directly buy quality soil from big brands, such as Danish peat soil. For those who are not afraid of trouble, it is recommended to dig the soil in the slightly more remote suburbs. The soil near the urban river is not recommended because it is not clear whether it has been polluted by heavy metals before. The excavated soil should be left open for more than a week to help remove the eggs. If it is not convenient to spread out, you can close it with a large black plastic bag and throw it in the sun for more than a week.

At the same time, considering that many people are planting on the balcony or terrace, I suggest that you can buy coconut brick and perlite >. If you cannot determine the EC value of the coconut brick within 0.5, you can basically use it after washing it two or three times after blistering. The sun-dried soil, soaked coconut bricks, and perlite (preferably soaked before use, not to be sucked into the lungs when used) >Mix by volume 2: 1: 1 or (1: 1: 1) . The treated soil, while being loose, breathable and water-retaining, can reduce the weight by more than 1/3 compared with ordinary soil. Balcony terraces have less load and are naturally safer.

The soil is selected to create a good growth foundation for the plant, grow strong from a young age, and lay a foundation for future growth and reduce pests and diseases.

Ventilation

The importance of ventilation to plants is self-evident, but for many novices, it is a large “minefield”.

If you pay attention to observation, you will find that the farmer’s uncle’s vegetables and crops are neat and tidy. This is of course not entirely for good looking, the biggest reason of which is to increase ventilation. Let the wind flow between plants can greatly reduce the occurrence of pests and diseases. Common diseases such as white powder and downy mildew are actually related to poor ventilation. The plants in the ground are like this, not to mention we are planting on the balcony and terrace, and we need to maintain good ventilation.

My suggestion

Many novices worry about not germinating when they are raising seedlings. Too much sprouting, so cute to look at, and feel hard-won, can’t always be heartless to remove some extra seedlings. I suggest that you leave a space when sowing, and don’t be vague when pulling out seedlings. Because if the distance between the seedlings and seedlings is too close, they will not compete for nutrition, and the ventilation will be poor. These “redundant” plants often become hotbeds of pests and diseases, and they often grow weak and diseased.

You can also purchase simple seedling trays for seedling cultivation.

Balcony planting, plantingDuring photosynthesis of objects during the day, carbon dioxide is consumed, and oxygen supply is required at night, so windows must be opened frequently to enhance ventilation.

In addition, ventilation is especially important for plants like tomatoes, because they are wind-borne plants, and pollination is required through air flow to produce more and better tomatoes.

Lighting

I’ve met a lot of newbies and complained to me, “Why do I always grow and die?”. I usually ask him, “How many hours a day does your balcony have light?”.

The growth of plants requires photosynthesis using sunlight through the leaves, converting carbon dioxide and water into carbohydrates, thus releasing energy. The vast majority of the leafy vegetables we grow need at least half a day of (more than four or five hours) . Fruits, vegetables, and fruit trees generally require full-day sunshine.

My suggestion

A plant with too little light always grows badly. If there is only a balcony for two or three hours in the house, I suggest growing some low light time such as ginger, spring onion, leek, celery, and lettuce Contented vegetables. Also, feed less. Because if there is too little light and too much fertilizer, the nitrate content in the leaves may be too high, which is not good for human health.

Seed

The highest appraisal of peasants is: there are species. Fruits produced by good seeds will taste much better than those produced by normal seeds, and have better yield and disease resistance. Therefore, it is necessary to choose good seeds.

My suggestion

The seed quality of Shouguang, the hometown of domestic vegetables, is good. Of course, if you can find high-quality foreign varieties that are suitable for the local climate, you can. It should be noted that the three plants of leek, strawberry and passion fruit are not suitable for starting from seeds.

If you plant the chives yourself, you can cut them for at least a year. Buying roots and planting them can be eaten after half a year, and can be cut continuously for two or three years. It is enough to sprinkle some ash on the second day after cutting the leek.

Strawberries are also not suitable for seeding. The fruit they produce is particularly small and tastes bad.

Passion fruit is a fruit I prefer to grow on the balcony, but it is not suitable for seed. Passion fruits grown from seeds may not produce much in two or three years. And you use cuttings to grow seedlings, there is enough space for them to climb, water and fertilizer management is proper, and you can bear hundreds of fruits that year.

Fertilizer

Farming is the most difficult to control on the balcony and terrace. Its special geographical location is (close to home, and close to neighbors) , Decided that the most important thing to use fertilizer is odorless. If you can buy thoroughly decomposed organic fertilizer, of course, if you want to try to make it yourself, there are some points to pay attention to.
