What do you need to pay attention to if you want to grow green vegetables in rural areas?

There are many kinds of green vegetables grown in rural greenhouses, and most of the vegetables require different growing environments and nutrients. Before cultivating and planting different types of vegetables, farmers need to correctly grasp the relevant growth characteristics, including the air humidity and humidity of the growing environment, the soil humidity, the degree of sunlight exposure, and common diseases in the growth.

In the process of planting vegetables, we should scientifically grasp the growth habits of vegetables and use a reasonable natural environment to create favorable growth conditions. Problems in the growth of vegetables should also be dealt with calmly and solved in time to ensure the final production output.

When choosing vegetable seeds, it is necessary to consider the factors of the local natural environment, especially the range of climate changes, the temperature difference between day and night, precipitation, etc. And when buying seeds, you must go to a regular manufacturer or a store with a production business license, pay attention to the production date and shelf life, and avoid buying counterfeit and expired seeds, which will affect vegetable production and economic benefits.

Pay attention to the selection of vegetable seeds, try to choose fuller seeds, different vegetable seeds have different selection methods, depending on the actual type of vegetables.

Before cultivating and planting vegetables, the selected seeds need to be sterilized, which can be completed by soaking in water or chemicals at an appropriate temperature. In terms of planting methods, it is advocated to implement the planting methods of intercropping and crop rotation, and to plant different kinds of crops in order according to the characteristics of vegetable growth in the same soil.

This kind of intercropping and crop rotation planting method can not only prevent and control diseases, insects and weeds, but also enable vegetables to fully absorb soil nutrients, adjust soil porosity, improve soil structure, make rational use of land resources to the greatest extent, and increase economic and ecological benefits.

Fertilization technology is the focus of planting green vegetable production technology, sufficient organic nutrients can provide rich nutrients for the normal growth of vegetables, which is conducive to increasing the yield of vegetables and ensuring the quality of vegetables.

At the moment of advocating sustainable development, it is best to use farmhouse fertilizer, organic fertilizer or vegetable compound fertilizer, and farmers are not encouraged to use chemically strong fertilizers during the planting process, otherwise it will cause damage to the soil. Most importantly, when using fertilizers, it is important to note that some ingredients should not exceed the permitted limits of the regulations.

It is necessary to pay attention to temperature control, light, fertilizer and water, soil, etc. The temperature is controlled at about 25 degrees, an appropriate amount of light is given, fertilizer is applied once every half month, compound fertilizer is selected, and loose and fertile soil is selected for planting.

It is necessary to stay away from factories, mining enterprises and traffic arteries that emit harmful substances, and ensure that the environment for our vegetable planting is clean and free of dust, toxic gas and ecological pollution. Choose fertile soil and do a good job of preparing the vegetable plot. Green vegetables should be applied less or no chemical fertilizers, and organic fertilizers should be applied to the farm.

It is necessary to choose varieties with high quality, high yield, and resistance to diseases and insect pests. Therefore, when we plant green vegetables, we must choose suitable vegetable varieties with high quality and high yield, strong stress resistance and good commerciality according to local climate and temperature characteristics and local conditions.

In addition to fertilizing and watering, we should also pay attention to one point that is easy to overlook, that is, the problems that can be caused by the reuse of land. Because the rural soil has been cultivated for decades, the soil nutrients are seriously depleted, and it is no longer loose and fertile. Soil depletion can be prevented by applying more farm fertilizer and less chemical fertilizer, and by rotating different crops.

Put the pre-broadcast preparation off: 1Before sowing, ploughing should be done as soon as possible, the soil should be exposed to the sun, and the residual root stubble and branches and leaves should be removed, and the remaining bacterial and insect sources in the soil should be eliminated.

2.Do a good job of seed treatment: choose warm water to soak seeds, that is, soak in warm water at 55 degrees for 15 minutes, which can kill the germs attached to the surface of the seeds.

Reasonably do a good job of intercropping, according to the different requirements of different vegetable varieties for light, water and fertilizer, high and short three-dimensional planting can be adopted. Three-dimensional planting of different types of vegetable varieties, three-dimensional planting of vegetables and edible fungi.

1. The selection of vegetable land, pollution-free green vegetable production base should be planned in a unified manner, and should be selected away from towns, away from industrial and mining enterprises and traffic arteries, soil, atmosphere and water sources are not polluted, the soil is fertile, the air is fresh, there is no dust and toxic gas pollution, and the ecological environment is good. The environmental quality is in accordance with the provisions of DB221-946-2001. The water source should be clean and free of harmful substances, and it is strictly forbidden to use stagnant water and industrial wastewater for irrigation.

The drainage ditch in the production area should be unblocked, reduce water accumulation, reduce soil moisture, keep the field clean, and the field shall not be left with dead branches and rotten leaves and stubble, timely cultivation and weeding, and seize the opportunity to properly dry or expose the soil during the stubble interval, promote soil ripening, improve the physical and chemical properties of the soil, eliminate stubble in time, and remove root stubble, dead branches, rotten leaves and sundries before ploughing.

2. Land preparation and disinfection, fine land preparation, shallow tillage and stubble, removal of crop residues, diseased plant residues, and rotten leaves, and transport them out of the field for deep burial or burning. Eliminate insect eggs and pupae, remove weeds in the field, eliminate the spread and parasitism of pests and diseases, and reduce the occurrence of pests and diseases. Seeds and seedbeds should be disinfected when raising seedlings.

Seed disinfection is mainly based on physical disinfection, using warm soup soaking, high temperature dry heat disinfection, if necessary, using high-efficiency and low-residue pesticides for soaking or seed dressing, seedbed can be paved to raise the soil temperature of the seedbed for disinfection, or disinfection with 40% formaldehyde. If the cultivation site is a greenhouse, it should be fumigated and disinfected with sulfur powder and other agents before transplanting seedlings.

3. Choose high-quality, high-yield disease-resistant and pest-resistant varieties, and improved varieties are the basis for high yield and high quality. In recent years, the practice in various places has fully proved that the selection of excellent vegetable varieties with good stress resistance is the internal factor and key technology for obtaining high-quality pollution-free green wood and vegetables, and it is the technology to get twice the result with half the effort. Therefore, all localities should take measures according to local conditions, vigorously promote excellent vegetable varieties with strong stress resistance, and select vegetable varieties with high quality and high yield, strong stress resistance and good commerciality, so as to lay a good foundation and create prerequisites for the production of green vegetables.

4. Do a good job in seed treatment, the seeds are soaked in nucleotide, and the seeds are soaked in warm soup with 50 55 warm water for 20 minutes to achieve seed disinfection. The use of nutrient bowl and greenhouse electric seedling raising, seedling management using high temperature to promote roots, early seedling refining and other measures to prevent growth, reduce seedling diseases, make seedlings grow robust, enhance disease resistance, strict screening of pest-free seedlings into the cultivation site.

5. Field fertilization technology, mainly organic fertilizer, minimize or do not use chemical fertilizer, apply high-quality circle fertilizer, compost, manure, biogas fertilizer, green orange manure, straw and other farm fertilizer 4000-5000 kg per mu before arable land, and turn into the deep part of the cultivated layer, and with shallow fertilization, 150-200 kg of rotting cake fertilizer per mu, and mix into compound bacterial fertilizer to inhibit the occurrence of diseases and insects. During the growth period, foliar sprays can be carried out with humic acid nutrient solution--- vital elements, and vegetable spirit to coordinate growth.
