The latest course of high-yield fertilization techniques for carrots

Carrot is a very popular root vegetable, and its planting area is very large in our country. The nutritional value of carrots is very high, so its market demand is still very large. When growing carrots, fertilization is very important if you want to increase the yield of carrots. So how to fertilize carrots? The editor has brought you the high-yield fertilization technology of carrots today. Let's take a look at it.

1. Characteristics of fertilizer requirement

The growth of carrots is very large, and the yield is relatively high, so the demand for fertilizer in the growth of carrots is still very large. There have also been professional data surveys that show that every time 1000kg is produced around carrots. Pure nitrogen, phosphorus pentoxide and potassium oxide fertilizer 2.4:0.8:5.7kg are needed respectively. In different growth stages of carrots, the demand for nutrition is also quite different. Generally speaking, the absorption of various nutrient elements is not very large in the second month after sowing. Generally speaking, when the root begins to expand in the middle and later stage, the demand begins to increase, and its nutrient absorption will also increase with the increase of growth. Potassium is the most, followed by nitrogen and phosphorus.

2. Application of base fertilizer

The roots of carrots are distributed deeply, so when we plant carrots, we should first pay attention to the selection of soil. Carrots are suitable for growing in fertile and soft sandy soil. Before sowing, we should also do a good job in soil preparation, ploughing the soil deeply and applying sufficient base fertilizer. Sufficient basal fertilizer is the key to ensure the early growth of carrots. If the basal fertilizer is insufficient, it is very disadvantageous to the germination of carrot seeds. The base fertilizer is mainly rotten farm manure, usually about 2200kg per mu. Combined with an appropriate amount of compound fertilizer to ensure adequate nutrition for the growth of carrots.

3. topdressing at the right time

When planting carrots, we should not only apply sufficient base fertilizer, but also pay attention to topdressing. It is generally necessary to top fertilize two or three times, about four weeks after the emergence of carrots, and about 3-4 true leaves for the first time. The fertilizer is mainly compound fertilizer such as potassium sulfate, and then the second topdressing is carried out when the carrot seedlings are fixed, and the fertilizer can be the same as the first time. Finally, the third topdressing was carried out during the root expansion period of carrots. The fertilizer for each topdressing can remain the same, but be careful to apply about 5 kilograms more each time than the last time.

4. Spraying foliar fertilizer

In addition to doing a good job of base fertilizer and topdressing, we should also pay attention to spraying an appropriate amount of foliar fertilizer. Carrots have a great demand for not only major elements such as nitrogen, phosphorus and potassium, but also trace elements such as boron in their growth. Carrots also have a great demand for boron, so we have to add boron to carrot plants by spraying foliar fertilizer. Generally, it should be sprayed once in the seedling stage and the peak period of leaf growth. During the period of fleshy root expansion, boric acid solution or borax solution can be used for spraying.

The above is a brief introduction to the high-yield fertilization technology of carrots. That's all for today's introduction. This article is for reference only. I hope it can help you all.
