Growing vegetables is inseparable from fertilizer, what are the main nutrients needed to protect fru

In order to grow fruits and vegetables with high yield and good quality, water and fertilizer management is a very core technology. Watering and fertilizing too often and using too much fertilizer will not only cause water and fertilizer waste, but also damage the root system.

In the whole process of planting vegetables in the soil, farmers habitually carry out fertilization according to the different growth links. For example, planting tomatoes, apply fertilizer once at the seedling stage to promote the growth of leaves and stems, and apply fertilizer once at the flowering stage, in order to better protect the flowers and flowers, fertilize the fruit at the fruit expansion stage to promote the growth of the fruit, and some farmers apply fertilizer again during the veraison period to promote the fruit to be evenly proportioned. Generally, a crop of fruit has to use chemical fertilizer 3 or 4 times, and the secret recipe of each fertilization is different, which is also the way of fertilization when planting soil.

Some farmers asked, is the soilless cultivation technology the same as soil cultivation? How many times should I apply fertilizer? High tertiary production or high secondary production?

Although the frequency of watering and fertilization is large, the amount of fertilizer applied at each watering is not large, which is not easy to lead to nutrient consumption. In this way, we can achieve the goal of watering with small water and applying thin fertilizer frequently, and can better meet the requirements of vegetable growth. When watering and fertilizing, only turn on the power switch, which is also very labor-saving.

However, when planting soil, due to its good water retention and solubility, it is likely to cause damage to the rhizome when watering and fertilizing too often.

Bio-fertilizers and their versatile fertilizers such as fulvic acid or humic acid can take care of rhizomes, improve soils, and also improve the availability of carbon dioxide. However, biological fertilizer and its humic acid fertilizer mainly play the role of harmonious green plant growth, although the trace elements are complete and have high efficiency, but its nutrient content is low, and it can not meet the needs of vegetable growth. Especially in the fruiting period, the nutrients of vegetables are required in large quantities, and it is difficult to achieve the necessary growth of fruits by applying this chemical fertilizer alone in winter.

Chemical pesticides such as water-soluble fertilizers have high trace element content and are fast-acting, which can quickly fill the nutrients needed for crop growth; Biological fertilizer or fulvic acid fertilizer can maintain rhizomes, improve soil, and harmonize plant growth. Only when the two are applied in conjunction with each other can we not only achieve the necessary nutrients of vegetables, but also nourish the roots and promote the trees.

The versatility of potassium fulvic acid from Juwuba mineral source + the abundant nutrients of Juwuba water-soluble fertilizer are scientifically and reasonably matched, which not only grows roots and nourishes roots, improves soil, increases soil temperature, but also gives water-soluble fertilizers and nutrients, immediately prevents vegetable deficiency disease, fills the necessary nutrients of vegetables, and improves drought resistance, which is a wise choice for fertilization in winter!

Growing vegetables requires farm fertilizer, organic fertilizer, plant ash, compound fertilizer, elemental fertilizer, etc. Before planting vegetables, it is necessary to apply an appropriate amount of base fertilizer in the soil, and the base fertilizer must be rotten to avoid burning vegetables with raw fertilizer. The application of basal fertilizer is mainly the need for the continuous growth of vegetables to promote the vigorous growth of plants.

Top dressing is mainly fast-acting fertilizers, such as human manure, ammonium sulfate, compound fertilizer, urea, etc.

Organic fertilizer, chemical fertilizer, compound fertilizer, farm fertilizer, nitrogen fertilizer, phosphate fertilizer, these fertilizers can help crops grow better.

When we grow vegetables, it is best to use organic fertilizers, such as cow manure, sheep manure, chicken manure, etc., which can promote the growth and development of vegetables.

First of all, melons, fruits and vegetables mainly include melon vegetables and nightshade vegetables. Melon vegetables mainly refer to cucumbers, watermelons, winter melons, pumpkin lanterns, such vegetables like moisture but not hard work, fertilizer but not fertilizer, suitable for fertile soil rich in organic matter. Nightshade vegetables mainly refer to tomatoes, eggplants, peppers, etc., mostly refer to the infinite growth type, while flowering, while fruiting, planting should pay attention to the contradiction between regulating vegetative growth and reproductive growth.

This type of vegetable has a large demand for potassium, calcium, and magnesium. The following are the main fertilization methods for melon and nightshade vegetables.

Fruits and vegetables:

1. For cucumbers, we can combine basal fertilizer and top dressing in fertilization. Basal fertilizer is applied into the soil before sowing or planting, combined with soil tillage, or used in a ditch about 15 cm away from the seed when sowing. Generally, 3,000 to 4,000 kilograms of high-quality farm fertilizer can be used per mu.

Diammonium phosphate and potassium sulfate can be mixed in small amounts. Top dressing refers to continuous fertilization in the process of continuous harvesting of cucumbers, so as to ensure the normal growth and development of fruits and the robust growth of plants. According to the soil condition and soil texture, general top dressing 3 4 times.

The fertilization method of base fertilizer and top dressing can also be used for the fertilization of watermelon and other types of melon vegetables.

2. For plants with developed root systems such as zucchini. This type of melon vegetable is mainly a fat-loving vegetable, and the nutrient requirement is higher than that of cucumber. When fertilizing, we should mainly use organic fertilizer, which must be combined with the use of phosphate fertilizer and potassium fertilizer.

The same should be done for base fertilizer and top dressing. Fertilizer can be applied in small quantities at the seedling stage, but as zucchini blossoms and bears fruit, the demand for nutrients increases, so we need to carry out continuous topdressing to ensure that the nutrient supply is sufficient.

Nightshade vegetables:

1. Nightshade vegetables mainly refer to tomatoes. Among them, it should be noted that we can carry out a small amount of fertilization in the seedling stage of tomatoes, and the demand for nutrients in tomatoes during this period is not large, so it is necessary to pay attention to the application of phosphorus fertilizer to tomatoes, and the demand for phosphorus fertilizer in tomatoes during this period is very small. However, the tomato harvest period is long, which requires us to provide nutrients to the tomato while harvesting during the harvest period.

2. For eggplant vegetables with underdeveloped root systems such as peppers. This type of vegetable has a wide adaptability to the soil, but it is mainly slightly acidic soil. These vegetables absorb different amounts of nutrients such as nitrogen, phosphorus, and potassium at different times.

In the budding to early flowering period, the plant grows fast, has a large demand for nutrients, and absorbs a lot. From the first flowering to fruiting is the vigorous period of vegetative growth and reproductive growth, and the demand for nitrogen is large, so nitrogen fertilizer can be used more. At the same time, we need to increase the application of calcium fertilizer, because the absorption of calcium by this type of vegetable gradually increases with the growth period.

In short, for the fertilization of vegetables, we should continue to fertilize according to the growth period and growth conditions, and provide the nutrients needed by fruits and vegetables in a timely manner.

Fertilization must be carried out according to the characteristics of the soil, phosphorus fertilizer and nitrogen fertilizer should be selected, or organic fertilizer and farmhouse fertilizer can be selected, and the temperature should be controlled at about 20 to keep sufficient light, so as to promote the growth and development of melons, fruits and vegetables.

Fruits and vegetables are generally suitable for growing on fertile sandy soil or clay loam, and they like rotting organic fertilizers, so deep ploughing and heavy application of rotting organic fertilizers, preferably oil cake meal fertilizer, have obvious effects on promoting early maturity of fruits and improving quality.

For the cultivation of different fruits and vegetables, reasonable fertilization is required. Different plants have different fertilizer needs and types. In the process of agricultural production, special attention is required.

It varies by variety.

You can refer to the following cucumber recipes.

1. Configure nutrient soil.

The use of plastic nutrient cup seedlings, the diameter of the nutrient cup is 8-10 cm, due to the fragile root system of cucumber, the nutrient soil configuration requirements are more stringent. You can choose from the following recipes:

1. Generally, 5 parts of decomposed cow dung or peaty soil, 2 parts of field soil, 2 parts of river sand, and 1 part of decomposed oil, mixed evenly after sifting, and 1 kg of diammonium phosphate per cubic meter is added.

2. 7 parts of garden soil and 3 parts of manure. If conditions permit, 15-25 kg of well-rotted chicken manure, l kg of superphosphate, and 5-10 kg of plant ash can be added to each l cubic meter of nutrient soil, and fully mixed.

3. Sieve the fertile paddy field soil finely, and choose a steel screen or bamboo screen with a square sieve hole. The sieved soil is mixed with 5:1 of fully decomposed pig manure, and then a small amount of potassium dihydrogen phosphate is added.

It is good to use potassium sulfate compound fertilizer, or water-soluble fertilizer.

It cannot be used alone, but should be used with chemical fertilizers. No matter what kind of soil is applied, there must be sufficient moisture to promote its rapid decomposition and transformation. When the temperature is lower than 10 or higher than 35, the fertilizer conversion and absorption will be hindered.

It should be applied correctly. First, in order to make the fertilizer reflect the long-term and fast-acting sustainable effect, all fields that apply bio-organic fertilizer should be equipped with about 30 kg of ammonium carbonate per mu, and then apply other nutrients according to the needs of different crops, and other fertilizers cannot be replaced by bio-organic fertilizer. The second is to apply basal fertilizer, and the dosage per mu does not exceed 50 kg.

In particular, plastic greenhouses can not be overused. Third, when the soil moisture is insufficient, it is necessary to resist drought and adjust moisture in time after application.

Basal fertilizer (base fertilizer) application.

Basal fertilizer, generally called base fertilizer, is a fertilizer that is applied before sowing or transplanting. When ploughing, the organic manure is evenly applied, and the fertilizer is turned into the soil with the ploughing, this method is simple, easy to operate, can play a good purpose of improving the soil, but in its uniform application to the soil, can not all or even most of the contact with the root system and be utilized by the root system, therefore, the fertilizer utilization rate is bound to cause excess waste, bring certain economic losses, and secondly, it is easy to produce soil obstacles. Therefore, this method is more suitable for planting crops with higher densities.

Top dressing application. There are two methods of topdressing for organic fertilizer: deep soil application and extra-root topdressing. Deep soil application generally applies organic fertilizer near the dense layer of the root system, and covers the soil after application to avoid the loss of nutrient volatilization. Extra-root topdressing is to mix the compost with 10 times the water evenly, take its supernatant after standing, and spray the fertilizer solution on the foliar surface of the crop with the help of a sprayer for foliar absorption.

It is used as seed fertilizer. There are many ways to use seed fertilizer, such as seed dressing, soaking, strip application, hole application, etc. Seed dressing is a method of dissolving or diluting fertilizer with a small amount of water, spraying on the surface of seeds, and mixing while spraying, so that the fertilizer solution is evenly stained on the surface of the seeds, and sown after drying. Soaking is to dissolve or dilute the fertilizer solution into a solution of a certain concentration, according to the liquid type 1:

10 ratio, put the seeds into the solution and soak for 12 24h, so that the fertilizer liquid infiltrates into the seed coat with water, and then sow after drying. After ditching or digging holes, fertilizer is applied into the ditch and hole of 3 5cm of the cultivated layer, and then sown near the fertilizer belt, and the distance between the fertilizer is kept above 3cm. Used as seed fertilizer, fertilizer requires the release of nutrients to be fast, can not be too acidic, too alkaline, the fertilizer itself has no toxic effect on seed germination, and the organic fertilizer that is fully decomposed after composting is a good seed fertilizer.

Used as seedling fertilizer.

Fully decomposed organic fertilizer, evenly released, comprehensive nutrients, is an ideal fertilizer for seedlings. Generally, 10% fermented organic fertilizer with sufficient fermentation is added to a certain amount of peat, fly stone or perlite, and the soil is mixed evenly to make seedling substrate.

Full-layer fertilization and concentrated fertilization of organic fertilizer.

Full-layer application is to sprinkle organic fertilizer all over the surface, and apply organic fertilizer into the whole soil layer through cultivated land, this fertilization method can be applied in the case of more organic fertilizer (4000 6000kg per mu) or crop density. Concentrated application into the soil is to apply compost near the root system of crops by ditching, and this fertilization method is worth using when there is less fertilizer (1500 3000 kg per mu) and soil fertility is relatively low.

It is better to use well-rotted organic fertilizer for cabbage. The nutrition of organic fertilizer is balanced, and the vegetables grown are more delicious.

It is better to be a natural fertilizer, such as manure, which has a relatively high nutritional value.

It is best to use farmhouse fertilizer, which can make the plant grow better, and avoid some pollution to make the cabbage taste better.

The vegetables are obviously fertilized, but the growth is still not satisfactory. In the process of vegetable growth, a lot of nutrients will be consumed, what are the fertilizers that promote root growth?

Microbial fertilizers and their versatile fertilizers such as fulvic acid or humic acid can maintain root systems, improve soils, and also improve the availability of carbon dioxide. However, microbial fertilizer and its humic acid fertilizer mainly play the role of harmonious green plant growth, although the trace elements are complete and have high efficiency, but its nutrient content is low, and it can not meet the needs of vegetable growth. Especially in the fruiting period, the nutrients of vegetables are required in large quantities, and it is difficult to achieve the necessary growth of fruits by applying this fertilizer alone in winter.

Mix the soil with a lot of chaff pig manure for subsoiling. There is also bioexcrement that is good with manure. Peanut bran:

Sesame juice residue, soybean cake, soybean cake, cottonseed cake and rapeseed cake are rich in a lot of nitrogen, phosphorus and potassium, which belong to acid and alkaline fertilizer after being made, and can be used as a quick-acting fertilizer when applied by water. Balanced fertilizer, a variety of fertilizers are used in combination with each other, and it is easier to reduce the phosphate content in vegetables than single basal fertilizer. The combination of nitrate and nitrogen and the spraying of trace element fertilizers can reduce the phosphate content in vegetables, especially in the combination of potassium fertilizer, which can promote protein synthesis and reduce the phosphate content in the body.

I firmly believe that everyone has planted vegetables, and also understand the necessity of the root system for vegetables, and if the root system grows well, it will have a greater effect on the growth of vegetables, which can enhance the vitality of vegetables and promote the rapid growth of vegetables. However, the root system of vegetables does not look good for no reason, and people must maintain the root system in order to make the root system of vegetables look more developed.

First of all, we must be clear that there are many bacteria in the soil, which are divided into bacteria and harmful bacteria, if there are many beneficial bacteria, then the soil will be rich, if there are many harmful bacteria, the soil will be poor. Therefore, when we plant vegetables, if we use some beneficial bacterial fertilizers, we can improve the digestive enzymes in the soil, improve the fertility of the soil, and reduce the disease to a greater extent.
