Hello, there are those methods of organic vegetable cultivation

Soilless cultivation of organic vegetable cultivation technology.

Currently, organic vegetables are grown in two ways:

One is soil planting

Organic vegetables planted in the soil can only be planted in the open air, not in the greenhouse, the greenhouse soil planting in biological and physical ways, can not control the damage of pests and diseases, can not produce organic vegetables.

The second is a new generation of soilless cultivation - organic melon and vegetable factory

It is a new planting technology that has been researched recently, and it is also a big breakthrough in organic vegetable planting technology. It can not only avoid chemical fertilizer pollution, but also solve soil-borne diseases and insects, overcome many problems in planting organic vegetables, and meet the requirements of organic vegetables for nutrients, water and so on to the greatest extent, and realize the production of organic vegetables with low input, low cost and high efficiency.

The vegetables grown in the nutrient solution soilless are chemically synthesized, and the poor quality cannot meet the organic standards at all.

Here's why:

Organic vegetables are of the highest quality without any chemical contamination, so the production and cultivation requirements are extremely strict. Organic Vegetable Growing Essentials:

1. Planting organic vegetables, prohibiting the use: chemical fertilizers, pesticides, hormones, herbicides and other chemical products.

2. The production site should be selected in a place without industrial pollution, and it should be far away from the highway.

3. There are strict requirements for water quality, soil heavy metals, and air quality.

4. There are strict requirements for planting organic vegetables, first find the technology and then dry, otherwise you can't grow organic vegetables.

The basic methods of soil organic vegetable cultivation are as follows:

First, how to eliminate fertilizer pollution in the soil

The main way is to take fallow to remove chemical fertilizer residues in the soil - that is, not crops, plant weeds and green manure, let them absorb the chemical fertilizer in the soil, and then use weeds and green manure as organic fertilizer to produce organic vegetables. This method is cumbersome, but it does solve the problem of residual chemical fertilizers in the soil. It is very difficult to eliminate pests and diseases in the soil, mainly by taking deep ploughing and exposure to the sun, stuffing the ground with water, etc., although it is very laborious, but because of the high density of the soil, it can only reduce the density of pests and diseases, and cannot eliminate pests and diseases.

The second is how to eliminate soil-borne pests and diseases

Growing organic vegetables, pesticides are not allowed, and it is difficult to achieve the desired effect by relying on biological and physical methods to control pests and diseases. In addition, chemical fertilizers cannot be used, and the nutrient requirements of vegetables cannot be met. To put it simply, nutrition can't keep up, and it's easy to be harmed by pests and diseases, and growing organic vegetables can't be high-yielding, and the cost is high.

Organic melon and vegetable factory - a new generation of soilless culture

It is a new planting method that has come out in recent years, it does not use soil, chemical fertilizers, and nutrient solution. Instead, leaves, weeds, straw manure, etc., and various agricultural wastes are used as raw materials to make culture materials to grow organic vegetables without soil. The culture material can be absorbed by the vegetables and turned into vegetables, which shows that the nutrition is particularly rich and completely solves the problem of providing melons and vegetables; At the same time, the culture material produced is clean and hygienic, without the source of diseases and insects, and completely overcomes the problem of soil-borne pests and diseases.

It not only solves the problems of chemical fertilizer pollution, soil-borne pests and diseases, but also meets the various requirements of vegetable growth; Open the convenient door of organic vegetable planting, eggplant can grow 5-6 meters high, tomatoes can grow 7-8 meters high, the yield is greatly improved, and the cost is only one-third of ordinary vegetables; You can take a closer look.

1. Site selection. Organic vegetables have strict requirements for the soil, generally organic vegetables need to be planted in sterile soil, and the soil needs to be able to give it a large amount of nutrients, usually need to be selected away from industrial areas, urban areas and other places with serious pollution, you can use garden soil mixed with organic fertilizer to grow organic vegetables.

2. Sow seeds. First of all, you need to dig out a ditch of 8-10cm, and then use a tool to properly loosen the garden soil, you can sow 2-3 seeds at intervals of 5-10cm, and cover a layer of soil on the seeds, if in winter, you should also cover it with a layer of plastic film, or cover a layer of grass felt, so as to make organic vegetables grow better.

3. Fertilization. In fact, the organic vegetable planting technology is very simple, whenever the organic vegetable seeds are sown into the soil, waiting for the vegetables to germinate, you can start fertilizing them, in the process of growth, you need to evenly apply 6000-8000 kg of nitrogen, phosphorus and potassium compound fertilizer, you can also apply an appropriate amount of organic fertilizer in the process, so as to make the organic vegetables grow better.

4. Precautions. In the process of planting organic vegetables, first of all, we must prepare excellent organic vegetable seeds, there are many genetically modified seeds in life, it is best not to use these seeds to sow seeds, not only the survival rate is low, the yield will also decline, and after the organic vegetables are planted, the growth process must be given enough light.

Clause. First, make an analysis of the local environment, soil conditions, moisture, etc. The organic vegetable planting base should try to choose a place with beautiful scenery, convenient transportation, and not too far from the city center, so that it is convenient for people to come to visit and can bring more economic value.

Clause. Second, after choosing a planting base, the next step is to consider what organic vegetables are better to grow. It is necessary to consider how to create more economic benefits in a limited area, and at the same time avoid pests and diseases of crops.

In addition, when growing organic vegetables, try not to grow out-of-season vegetables, because out-of-season vegetables are not easy to grow, require higher technology, and are also costly.

Clause. Third, after determining the vegetable variety, the next step is to face the problem of soil treatment. This is a very tricky problem, some planting sites have been planted for many years, such soil may hide a lot of pests and diseases, you can choose to soak the soil for a long time or deep ploughing.

Clause. Fourth, fertilization has a very important role in the planting of organic vegetables, according to the different physical and chemical properties of the soil, fertilizer can be divided into top dressing and base fertilizer two, we should choose fertilizer according to different situations.

1. Land conditions: The land on which organic vegetables are planted must be complete plots, and organic vegetables cannot be planted on the land of conventional production, but they can be planted in the soil of organic conversion. There must be boundaries between the organic vegetable production base and the conventional plot, such as rivers, hills, artificial separation zones, etc.

2. Soil quality conditions: According to the provisions of the "Soil Environmental Quality Standard GB15618-1995", the soil for planting organic vegetables must meet the secondary standard.

3. Fertilizer conditions: organic fertilizers must be used for organic vegetables, so that organic matter can be returned to the soil, and soil fertility can be maintained or increased and soil biological activity can be improved. Do not use synthetic chemical fertilizers, or nutrients such as nitrates, phosphates, chlorides, etc.

1. Variety selection: the selected varieties and seeds, the seeds must ensure that they are not chemically and genetically modified.

2. Choose a plot: The plot should be far away from polluted areas such as industrial areas, mining areas, and urban areas, and it should be soft and fertile, and apply well-rotted organic fertilizer as the base fertilizer before planting.

3. Sowing into the soil: Generally, it is directly sown or sown, covered with thin soil after planting, and the temperature and moisture are reasonably controlled.

4. Post-management: frequent top dressing, application of well-rotted organic fertilizer, but also to provide a suitable environment.

<> cultivation management: cultivation of organic vegetables. Supporting cultivation techniques should be adopted.

The implementation of crop rotation and clean farmland, through the cultivation of strong seedlings, grafting and root replacement, ridge cultivation, plastic film covering, reasonable dense planting, plant adjustment and other technologies, make full use of light, heat, gas and other conditions, the use of crop rotation, after the harvest of the previous stubble vegetables, thoroughly clean the base, to create an environment conducive to the growth of vegetables, in order to achieve the purpose of high yield and high efficiency.

Fertilizer use. The fertilizers used in the production of organic vegetables are mainly organic fertilizers. Including animal manure, plant fertilizer, green manure, plant ash, cake fertilizer, biogas fertilizer, etc., in addition to organic special fertilizer certified by organic certification bodies and some microbial fertilizers.

1. Harmless treatment of fertilizer.

Organic fertilizer needs to be harmless in 2 months before application, there are two methods: one is to pour water and mix the fertilizer with wet accumulation, cover it with plastic film, make it fully rotted, and the fermentation temperature is above 60 degrees, which can effectively kill the diseases, insects and weeds in the farm fertilizer, and the treated fertilizer is easy to be absorbed and utilized by vegetables. The second is to use the biogas digester to enter the organic fertilizer into the biogas digester for fermentation, and the biogas slurry or biogas residue is used as organic fertilizer.

2. How to use fertilizer.

Amount of fertilizer. When using fertilizer, the land for organic vegetable cultivation should be planted with fertilizer at the same time. The ratio of animal manure to plant waste should be 1:1.

Apply sufficient basal fertilizer. 80% of the total amount of fertilizer applied is used as basal fertilizer. The fertilizer is evenly applied into the tillage layer.

to facilitate root absorption. Combined with land preparation, there are 45 hectares of manure or biocompost 45 to 75 tons. Conditional organic compound fertilizer can be used as seed fertilizer, the amount of use is 1500 kg hectares.

The method is to apply in the furrow or hole before transplanting or sowing, and the fertilization depth is 5 10 cm.

Skillful topdressing. Combined with watering and soil cultivation for soil topdressing, mainly using human manure and biological fertilizer. Foliar spraying can also be carried out, and bio-organic foliar fertilizer is selected during the growth period, sprayed once every 7 10 days, and sprayed 2 or 3 times in a row.

When the vegetables grow to 3-4 leaves, the fertilizer that has been dried and refined is evenly sprinkled into the vegetable field, and watered in time. For planting vegetables with larger roots and more concentrated roots, you can open a ditch to fertilize, do not break the root system when opening a ditch, and water it in time after covering it with soil. It should be noted that fertilization should be flexibly matched according to the characteristics of fertilizer, different soil properties, different vegetable types and different growth and development periods.
