Is it okay to plant crops without fertilizing one season, and can you fertilize just planting vegeta

You must be surprised to hear that we don't use fertilizer when we farm? Can crops grow taller without fertilization? The answer is: yes. And it's very long!

If you pay a little attention, you will find that in nature, no one fertilizes the trees in the primeval forest or the weeds on the roadside, they still grow healthily, and many wild fruits have a natural flavor that we can't artificially cultivate.

Microorganisms are the best of soil vitality, the health of the microbial system is the key to the growth of crops, and the complexity of the microbial world is far beyond human control, a large number of chemical or natural substances that cannot appear in this land will cause serious interference to microorganisms, when the microbial system is disturbed, crops are easy to get sick.

The soil itself already contains all the nutrients needed by crops, and if additional chemical fertilizers and organic fertilizers are added, it will become a stumbling block for the earth, crops and human health.

What plants need to grow depends on the exchange of microorganisms in the roots and soil, and the chemical fertilizers of customary farming methods and the organic fertilizers of organic agriculture force crops to absorb the nutrients that humans think they need. One way of growing is that plants actively exchange according to their own needs, and the other is passive indoctrination of plants, which way do you think plants will be healthier?

The reason why vegetables in the field do not grow well without fertilization is that they are overcared for and lose their ability to find nutrients from the land to survive. As long as you stick to no fertilizer and plant it yourself a few times, the crop will be able to regain its ability to grow naturally, and the taste of the crop itself will gradually appear.

Of course, we don't use pesticides, fertilizers, herbicides, or other toxins of modern agriculture, and we don't even use fertilizers commonly known as organic fertilizers, even soybean meal, rapeseed meal, and human and animal manure.

As long as we stop fertilizing and mutilating our Mother Earth, she will become cleaner and more active. When Mother Earth is restored to its original vitality, the increase in crop yields is a natural consequence.

There is also a big advantage of not applying manure and urine fertilizer, that is, our farm never smells stinky, whether it is watering vegetables yourself or picking by friends, you don't have to wear a mask! formula, so there must be no need to copy the format to the WeChat device or WeChat public platform.

Depending on your field, you don't apply fertilizer in one season, and some of the crops that can be planted are different, and the amount of fertilizer you need is also different.

Vegetable seedling fertilization can be directly sprinkled with compound fertilizer, do not sprinkle chemical fertilizer in the heart leaves, so as not to cause seedlings to burn, it is best to combine watering each time top dressing.

Sufficient application of basal fertilizer: If a large amount of fertilizer is applied at one time before vegetable planting, such as rice husk manure, chicken manure, commercial organic fertilizer, compound fertilizer and medium and trace element fertilizer, etc., the base fertilizer is sufficient, and the nutrients in the soil can fully meet the needs of vegetable seedling growth, and there is no need to apply fertilizers such as nitrogen, phosphorus and potassium at the seedling stage.

Because after the vegetable is planted, part of the organic fertilizer or chemical fertilizer begins to be gradually decomposed by soil microorganisms, releasing nutrients that can be directly utilized by the vegetable roots.

At the same time, if more nitrogen fertilizer is used at the seedling stage, it may also cause vegetable seedlings to grow vigorously, plant joints are too long, and the root system is shallow to take root, and the main consequence of plant growth is poor flower bud differentiation and delayed flowering and fruiting.

Of course, after the autumn stubble vegetables are planted, due to weather and other reasons, the crops are slow to sprout, and they can be applied as appropriate to apply aromatic root and antibacterial 968 seedling stage fertilization to improve the soil environment, promote slow seedlings and deep root system, and prevent disease and strengthen trees.

Insufficient basal fertilizer application: Some vegetable farmers plant vegetables directly without turning the ground after the stubble crops are stubble, and some new sheds grow vegetables, and the application of base fertilizer is often insufficient.

In these cases, fertilizers should be applied at the seedling stage of crops to ensure sufficient nutrients for the growth of crop seedlings, to avoid stunted growth and development, disease resistance, and stress resistance.

Insufficient application of basal fertilizer.

Vegetable seedlings should be applied in a timely manner with fully water-soluble fertilizers, such as Le, Fangrun, etc., 5 8 kg per mu.

It is best not to apply fertilizer at the seedling stage, and wait for a period of growth before talking.

Do not fertilize first, so as not to cause seedling burning, fertilizer damage, and affect the development of seedlings.

Of course, it's in the morning. At this time, the temperature is suitable, the moisture is just right, and the sunlight is not strong, so it can absorb nutrients very well.

I think the timing of fertilization is different for every crop. For example, corn is at its peak when it absorbs nutrients. It is after jointing and up to the time of the big flare.

In the evening, because the sun sets in the evening, the low fertilizer utilization rate caused by exposure to the sun can be avoided, and the fertilizer utilization rate can be maximized.

Compound fertilizer refers to chemical fertilizer containing two or more nutrients, compound fertilizer has the advantages of high nutrient content, few side components and good physical properties compared with simple fertilizer, and plays a very important role in balanced fertilization, improving fertilizer utilization rate and promoting high and stable yield of crops. But it does not mean that it is enough to use compound fertilizer, many compound fertilizers only contain 2-3 elements, which is far from enough for the growth of crops.

What kind of crop do you want, what kind of fertilizer does it need, you need to fertilize scientifically, if you are troublesome, you can use special fertilizer, such as cucumber, you can use carbon to fill vegetables, and wheat can be used to use wheat.

Do not fertilize when ploughing, but fertilize before sowing, such as bed soil before sowing.

20 days before sowing, the seedbed was fertilized as the last fertilizer, and inorganic nitrogen, phosphorus and potassium fertilizers were applied to increase the content of available nutrients, improve the fertilizer intensity and balance nutrition. Generally, 30 50 grams of urea, 100 150 grams of superphosphate, and 40 50 grams of potassium chloride are applied per square meter, and the mixture is sprinkled on the bed surface in 3 times. After each spreading, it must be raked sufficiently to make the fertilizer evenly mixed in the 0 10 cm soil layer.

Finally, the available nitrogen, phosphorus and potassium contents of the bed soil reached the fertility levels of 150 mg kg, 20 30 mg kg and 120 150 mg kg, respectively. At present, many places on pre-sowing fertilization are selected seedling enhancers, which can omit many operation links, save labor and labor, are safe and reliable, and have good effects, which are worthy of vigorous promotion and application.

Of course, you can, as long as the soil is moist and the fertilizer is not too close to the seeds.

Autumn vegetable planting can not be done without fertilization, the principle of vegetable fertilization is mainly organic fertilizer, supplemented by other fertilizers; It is mainly based on multi-compound fertilizer, supplemented by single-element fertilizer; It is mainly based on basal fertilizer, supplemented by top dressing. The use of chemical fertilizers can be limited as much as possible, and some fertilizers can be applied selectively to a limited extent if needed. Organic fertilizers such as human manure and manure should be fully fermented and rotted, and should be rinsed with water after topdressing.

In addition, before the flowering of vegetables, the young fruit stage, and the fruit expansion period, spray "vegetable fruit strong tiling" once each time can make the vegetable nutrient duct thicker, increase the amount of nutrient delivery, strengthen the seedlings and strong pedicles, meet the physiological needs of fruit development, and avoid weak flowers and flower drops, fruit drops and fruit cracks caused by malnutrition. Improve fruit expansion and vigor, and produce high-yield and high-quality vegetables. Add an appropriate amount of "new high lipid film" when spraying foliar fertilizer every time you spray and spray foliar fertilizer, improve the efficiency by more than 300%, overcome many defects such as high pesticide residues and reduced quality, and achieve the purpose of saving pesticides and fertilizers, improving grades, increasing yields, and producing pollution-free vegetables.

Suffering from frost damage will also affect the growth and development of vegetables, greatly reduce the quality, in addition to taking cultivated soil, ditch drainage, lifting the box to increase temperature, smoke or set up wind barriers, timely and comprehensive and uniform spraying of "tree guard", quickly form a layer of protective film in the plant, film-forming substances can protect vegetables from frost damage, improve cold resistance, disinfection and frost prevention.

Generally speaking, the bottom fertilizer is to be filled, but the top dressing should not be less, it is best to top dressing once or twice as needed.

As the saying goes, "the lazy man grows beans". Because everyone knows that legume crops do not need to be fertilized, and they can almost sit back and wait for harvest after planting, which is a kind of "lazy crop".

Why don't legume crops need to be fertilized? This is because its roots combine with rhizobia in the soil to form nodules, and rhizobia convert nitrogen in the air into a form that plants can directly use, and supply plants with a steady stream of nutrients. This means that each leguminous plant has a small nitrogen plant, which is more than enough to be self-sufficient.

Rhizobia are everywhere in the soil, and endemic legumes are attractive to it. This is because leguminous plants have a nitrogen-fixing gene, which works at a certain stage of root development, signaling rhizobia in the soil to welcome them to "guest" and "settle".

When genetic engineering was in the ascendant, an extremely moving idea naturally jumped out: how great it would be if the nitrogen-fixing genes of leguminous crops were transferred to rice, wheat, and cotton! Not to mention that hundreds of millions of tons of chemical fertilizer are saved, and not to mention that a lot of labor is saved for fertilization, it is also a good thing for improving soil structure and protecting the ecological environment.

So. In the whole plant genetic engineering, the transfer of nitrogen-fixing genes has become the crown jewel. Many scholars have worked tirelessly to capture the fortress as soon as possible.

Now, nitrogen-fixing genes, which are the core of the inherited nitrogen-fixing ability in nitrogen-fixing microbial cells, have been able to be transferred between bacteria in the prokaryotic kingdom, and further research is underway to transfer it to eukaryotes, yeasts.

China has made gratifying achievements in biological nitrogen fixation. Safflower sap has been applied in rural areas such as Jiangsu and other places, and the effect of increasing yield is remarkable. The research on the application of biotechnology to induce nodulation and nitrogen fixation in non-leguminous plants such as wheat has also made preliminary breakthroughs, and has been confirmed in Sino-Australian and Sino-German cooperation.

Chinese scientists have used genetic engineering technology to select and breed ammonia nitrogen-tolerant bacteria suitable for rice applications in China, which is a wonderful "yield increasing bacteria". When the roots of rice are inoculated with this fungus, the yield increase equivalent to 2 kg of pure nitrogen fertilizer per 666 m2 of land can be obtained. In the future, this ammonia-tolerant nitrogen-fixing bacteria will be widely promoted in rural areas across the country.

At present, some people have transplanted a nitrogen-fixing bacterium into carrot cells, and others have introduced pea rhizobia into wheat and oilseed rape cells.

It seems that the day is not far off when this grand blueprint will be realized.
