What are the pros and cons of soilless and soil based planting of vegetables?

Compared with soil-based planting, the method of soilless planting is used

Pros: 1) Fewer pests and diseases. Just control the nutrient solution.

Sterile, the surrounding environment is clean, and the plant is very difficult to get sick.

b) Plants have a higher assimilation rate. The same is a bag of fertilizer, applied in the ground, the plant can only absorb a part, a large part is left in the land, if the nutrient solution is used, can be repeatedly supplied to the plant to absorb, improve the utilization rate.

3) Strong controllability, suitable for factory production. Don't worry about rainy or little rain, high temperature or low temperature, as long as the nutrient solution and the surrounding environment temperature are controlled, annual production can be realized.

4) The quality of vegetable products is better and the production cycle is faster. According to the different growth periods of plants, the selection of nutrient solutions with different concentrations and element ratios is more conducive to plant growth, faster maturity and higher quality of vegetable products due to fewer pests and diseases.

Location: The upfront investment cost is large, and the technical ability required for management is high.

In the long run, it is an inevitable trend for vegetables to adopt soilless cultivation and implement annual production.

Cultivated vegetables in life are mainly divided into soilless cultivation and soilless culture, but soilless cultivation has many drawbacks, mainly slow growth, high cost, difficult to take care of, generally the nutrients of soilless cultivation plants can not be sufficiently provided, and the cost required in the hydroponic process is very high, and the water needs to be changed frequently, which is much more complicated for soilless culture.

The way of cultivating vegetables in life is mainly divided into soilless cultivation and soilless cultivation, but soilless cultivation has many drawbacks, so what are the disadvantages of soilless cultivation of vegetables, first of all, the growth rate of vegetables using soilless cultivation method is very slow, and the nutrients required by the plant can not be fully provided, and the trace elements in the soil can make up for the lack of nutrients.

Generally, vegetables adopt the way of soilless cultivation, it is necessary to need a large amount of nutrient solution, mainly to ensure the normal growth and development of plants, and the cost of using these nutrient solutions is relatively high, if it is completely unnecessary for a cheap vegetable, the use of soiled culture will be preferred to soilless culture.

Usually the use of soilless cultivation vegetables mainly in hydroponics, then to ensure the quality of water, generally rainwater or river water, pond water is the best, if it is tap water at home, usually to be placed outdoors to stand, and in the cultivation process often change the water, compared to soil cultivation is much more complicated.

Cultivated vegetables in life are mainly divided into soilless cultivation and soilless cultivation, but soilless cultivation has many drawbacks, if the main jujube liter grows slowly, the cost is high, it is difficult to take care of, and the nutrients of the general soilless cultivation plants are not sufficiently provided, and the cost required in the hydroponic process is very high, and the water needs to be changed frequently, which is much more complicated for soilless cultivation.

1. Slow growth.

The way of cultivating vegetables in the living family is mainly divided into soilless culture and soilless culture, but soilless cultivation has many drawbacks, so what are the disadvantages of soilless cultivation of vegetables, first of all, the growth rate of vegetables using soilless cultivation method is very slow, and the megavolt nutrients required by plants are not sufficiently provided, and the trace elements in the soil can make up for the lack of nutrients.

2. High cost.

Generally, vegetables adopt the way of soilless cultivation, it is necessary to need a large amount of nutrient solution, mainly to ensure the normal growth and development of plants, and the cost of using these nutrient solutions is relatively high, if it is completely unnecessary for a cheap vegetable, the use of soiled culture will be preferred to soilless culture.

3. Difficult to take care of.

Usually the use of soilless cultivation vegetables mainly in hydroponics, then to ensure the quality of water, generally rainwater or river water, pond water is the best, if it is tap water at home, usually to be placed outdoors to stand, and in the cultivation process often change the water, compared to soil cultivation is much more complicated.

First, high yield and high quality.

We have made a comparison and planted early spring melons at the same time, but the cultivation methods are different, one is cultivated with substrate and the other is cultivated with soil. Substrate-grown melons are more robust than soil-grown plants, and they are marketed in the morning for a week, and there is no wine heart, so the sweetness is high. In addition, by July, the melons planted in the soil have already been pulled, and another substrate cultivation greenhouse is still bearing melons, and the yield is higher.

Because the soil has strong water retention, it cannot balance the relationship between water nutrients and oxygen, and the more water, the less oxygen it is exposed to, and the root growth is poor. Regardless of the substrate used, the air permeability is better than that of soil, which can create a suitable growth environment for root growth. If the root system grows well, the aboveground part can be strong, the seedlings are slow, the growth is fast, the melon is early, and the commerciality is good.

Soilless cultivation provides good growing conditions for vegetables, which is conducive to improving yield and quality.

Second, there are fewer pests and diseases.

In the past, we planted tomatoes and cucumbers in the soil, and soil-borne diseases such as root-knot nematodes and root rot were very serious. When there is a crack in the stalk during planting, the bacteria will infect the plant along the wound, and the older seedlings will die. When the soil is planted, there is a lot of watering loss, and the humidity in the greenhouse increases, which is also prone to gray mold.

Soilless cultivation of vegetables, planting troughs can isolate germs and insect eggs in the soil, reduce the occurrence of pests and diseases, and reduce the use of pesticides. In addition, it solves the problem of soil stubble, and the water and fertilizer utilization rate of soilless cultivation is high, which changes the situation that the soil watering loss rate is high and fertilizer cannot be applied. After each harvest, the substrate is disinfected, rinsed and prepared for planting.

Third, save labor and effort.

Before the soil is planted, it is necessary to plough and ridge the soil, which is laborious and laborious. After planting for two or three years, soil treatment and disinfection of stuffy sheds are also carried out. The utilization rate of water and fertilizer is low, and it can only be fertilized many times, which consumes water and fertilizer, and requires more labor.

Soilless cultivation does not need to be tilled, the substrate is reused, and it is also very convenient to change the stubble, which saves a lot of labor. In addition, the greenhouse is equipped with automatic watering and fertilization equipment, such as watering every two hours, just set it up, turn on the switch, save labor and effort, and the utilization rate of water and fertilizer is also very high.

The above three advantages of soilless cultivation of fruits and vegetables are very obvious, which changes the cultivation mode and avoids problems when planting in the soil. Now the cost of soilless cultivation is also very low, and the selection of resources is a low-input and high-efficiency cultivation mode.

1. There are more than 20 kinds of leafy vegetables suitable for short-season planting, such as cream lettuce, purple leaf lettuce, rosa wrinkled leaf lettuce, Roman erect lettuce, large speed lettuce, red oak leaf lettuce, green oak leaf lettuce, yellow heart bitter endive, large-leaved chrysanthemum, red stem leaf beet, yellow stem leaf beet, white stem leaf beet, celery, water celery, green rape, purple rape, small pine cabbage, watercress, water spinach, thousand-tendon white-stemmed Beijing water cabbage, golden mustard greens, bright chain egg leaf lettuce, etc. It was harvested once 25 30 days after planting, and the weight of each plant was 150 200 g. You can also peel off the outer leaves and harvest them many times, the colors are red, yellow, dark green, light green, purple and so on, and the public can plant several colors of vegetables on one device, forming a landscape of different wind and talk.

2. Fruits and vegetables. There are mainly tomatoes, cherry tomatoes, bunches of tomatoes, eggplants, peppers, bell peppers, mini cucumbers, ornamental pumpkins, beibei and locust buried pumpkins, zucchini, melons, pocket watermelons, etc.

Vegetables suitable for soilless planting are: cream lettuce, purple leaf lettuce, rosa wrinkled leaf lettuce, Roman erect lettuce, big speed lettuce, red oak lettuce, green oak lettuce, yellow heart bitter endive, large-leaved chrysanthemum, chrysanthemum, red stem leaf beet, yellow stem leaf beet, white stem leaf beet, celery, water celery, green rape, purple rape, komatsu, watercress, water spinach, thousand tendon white stem Jing waterweed, golden mustard and other green leafy greens are suitable.

1. Tomato, soilless cultivation of tomato is generally carried out in greenhouses, and this cultivation method can be carried out all year round. The soilless cultivation of tomato in solar greenhouse can be determined according to the performance of the greenhouse, and the stubble production is generally dominated by winter and spring stubble and early spring stubble. 2. Bitter gourd, bitter gourd is an annual climbing herbaceous plant of the Cucurbitaceae family, the stem, branch, petiole and flower stalk are covered with pubescence, axillary tendrils, the conditions required for cultivation are not strict, the growth is vigorous, the fruit setting ability is strong, the harvest time is long, and it is very suitable for soilless cultivation.

3. Eggplant, eggplant in recent years, the area of solar greenhouse and greenhouse cultivation has been expanding, but due to continuous cropping and heavy cropping, diseases, especially soil-borne diseases, have occurred seriously, and the use of soilless cultivation can overcome this problem, and it has gradually become popular in recent years.

1. Ginger. Many places have also begun to carry out ginger soilless cultivation, which can reduce the incidence of pests and diseases, and can increase the yield of ginger, so soilless cultivation is very suitable for ginger growth.

2. Eggplant. Nowadays, many places also use the greenhouse method to cultivate eggplant, but when eggplant is traditionally cultivated, it has a great impact on the yield of eggplant due to the spread of various soil diseases, so in order to reduce eggplant diseases and pests, many places have begun to carry out soilless cultivation to manage eggplant seedlings, and the quality of finished eggplant is very high.

3. Cucumbers. Cucumber is a relatively high yield vegetable in China, but because it has soil cultivation, there will be pests and diseases mainly because the soil is rich in germs, and the nutrition is not sufficient, so people began to use soilless cultivation, which can reduce the use of pesticides and fertilizers, and can also reduce the cost of planting.
