What are the commonly used fertilizers when growing vegetables?

Some vegetables eat leaves, some eat fruits, some eat flowers, leaf nitrogen fertilizer fruits are high in potassium, and can flexibly adjust the properties of fertilizers according to the different vegetables planted, among which urea, potassium fertilizer, compound fertilizer and farm fertilizer are more commonly used.

Fertilizers for planting vegetables include farm fertilizer, such as compost, manure, biogas fertilizer, green manure, crop straw, mud fertilizer, cake fertilizer, etc. Biological fertilizers, including humic acid fertilizers, rhizobia fertilizers, phosphorus bacteria fertilizers, compound microbial fertilizers, etc.

Commonly used chemical fertilizers generally include urea, diammonium phosphate, potassium sulfate, some compound fertilizers and some instant fertilizers that can be sprayed on the foliar surface.

1.It is nitrogen, phosphorus and potassium compound fertilizer + urea, which is a full chemical fertilizer method, which can also quickly promote the growth of melon and fruit seedlings, but it is not very recommended, and chemical fertilizer is only used in nutritional emergencies.

2.It is urea + farm fertilizer + plant ash, urea can quickly supplement nitrogen nutrients, farm fertilizer and plant ash can gradually supplement potassium, phosphorus, calcium, boron and other nutrients, and can also quickly promote the growth of melon and fruit seedlings.

3.It is a whole farm fertilizer, using fermented liquid fertilizer (or pig manure water) + farm fertilizer, which has a large amount of nitrogen nutrients in the liquid fertilizer, but it will be slightly milder.

You can use farmhouse fertilizer, nitrogen fertilizer, and phosphorus fertilizer, which are all conducive to the growth of plants and can make plants more vigorous.

Mix the soil with a large amount of rice husk and chicken manure and turn it deeply. When starting to plant base fertilizer, it is generally supplemented with balanced potassium sulfate compound fertilizer, appropriate medium and trace elements. Due to the new soil, the soil fertility is poor, and sufficient fertilizer should also be supplemented in the process of top dressing.

It doesn't cost you money to improve the soil, and if you don't have it, it's not expensive to buy some. In addition to using rice husk and chicken manure, the newly opened vegetable plot can also buy organic fertilizer to improve the soil and make base fertilizer, which is also very convenient. In the older generation, there is also the habit of growing vegetables with the residue left over after squeezing oil at home (we call vegetable withering and tea withering in rural areas).

The saponins and glycosides contained in vegetable withered and tea withered have a certain control effect on soil pests.

Organic fertilizers. It is to use well-rotted animal manure, or fermented peanut cake, cottonseed cake, rapeseed cake, etc., to grow vegetables, and use their organic ingredients to provide the nutrients needed for the growth of the grown vegetables. This kind of organic fertilizer has a long fertilizer effect, especially it is recommended to choose the sheep manure that is re-added and re-rotted, such as the process of opening gold rotted sheep manure.

This kind of manure has few harmful bacteria, contains beneficial bacteria, does not burn the roots, does not hurt the roots, and is a good maintenance of the root system and soil.

The base fertilizer is mainly organic fertilizer, which should account for 60% of the total fertilizer requirement in the life of the crop. Generally, the production of protected areas is better with chicken manure and pig manure with higher nutrient content, but we must pay attention to full decomposition, and the process of decomposition will produce higher temperature topdressing, soil fertilization and foliar fertilization. Soil topdressing is mainly carried out in combination with watering and soil cultivation during the vigorous growth period of vegetables, mainly using human manure and bio-poly fertilizer.

Foliar fertilization can be used at the seedling stage and growth stage.

Cake fertilizer: sesame sauce residue, soybean cake, peanut cake, cottonseed cake, rapeseed cake contains a large amount of nitrogen, phosphorus, potassium, after the preparation belongs to the acid fertilizer, more suitable for acidic soil flowers, dry application of fertilizer effect slowly release, water application can be used as a fast-acting fertilizer. Vegetable waste.

Can be used as a composting feedstock. The minimum standard for composting: the temperature of the stack is above 55 degrees Celsius for 10 days; The trough compost temperature is above 55 degrees Celsius and kept for 7 days.

Mix the soil with a large amount of rice husk and chicken manure and turn it deeply. There is also animal manure that has been well decomposed. Cake fertilizer: sesame sauce residue, soybean cake, peanut cake, cottonseed cake, rapeseed cake contain a lot of nitrogen, phosphorus, potassium, after the preparation is acidic fertilizer, can be used as a quick-acting fertilizer when water applied. Vegetable waste.

Nitrogen fertilizer, phosphorus fertilizer, etc. Nitrogen fertilizer can increase nutrients, and phosphorus is also a nutrient that plants need.
