How to fertilize carrots for high yield? Latest technical method tutorial

Carrot is a very popular root vegetable, and its planting area in our country is very large. The nutritional value of carrots is very high, so its market demand is still very large. When planting carrots, if you want to increase the yield of carrots, then fertilization work is very important. So how should carrots be fertilized? Today, the editor brings you the high-yield fertilization technology for carrots. Let's take a look below!

1. Fertilizer requirement characteristics

The growth amount of carrots is very large, and the yield is also relatively high, so during growth, carrots still have a very large demand for fertilizer. Professional data surveys have also shown that for every about 1000 kg of carrots produced, the requirements for pure nitrogen, phosphorus pentoxide, and potassium oxide fertilizer are 2.4:0.8:5.7 kg respectively. And at different growth stages of carrots, the demand for nutrients also differs greatly. Generally, in the second month after sowing, the absorption of various nutrient elements is not very large. Usually in the middle and late stages, when the root begins to expand, the demand begins to increase, and the nutrient absorption also increases with the increase in growth amount. Potassium is the largest, followed by nitrogen and phosphorus.

2. Application of base fertilizer

The root distribution of carrots is relatively deep, so when planting carrots, we must first pay attention to doing a good job in soil selection. Carrots are suitable for growing in sandy loam soil with sufficient fertility and looseness. Before sowing, we should also do a good job in soil preparation, deeply plow the soil, and apply sufficient base fertilizer. Sufficient base fertilizer is the key to ensuring the early growth of carrots. If the base fertilizer is insufficient, then it is very unfavorable for the germination of carrot seeds. The base fertilizer is mainly decomposed farmyard manure, usually about 2200 kg per mu. Then combine it with an appropriate amount of compound fertilizer to ensure that carrots have sufficient nutrients for growth.

3. Timely topdressing

When planting carrots, we must not only apply sufficient base fertilizer, but also pay attention to doing a good job in topdressing. Generally, topdressing should be done about two to three times. About four weeks after carrot emergence, when about 3-4 true leaves have grown, carry out the first fertilization. The fertilizer is mainly compound fertilizer such as potassium sulfate, and then carry out the second topdressing when carrots are thinned. The fertilizer can be the same as the first time. Finally, carry out the third topdressing during the carrot root expansion period. The fertilizer for each topdressing can remain unchanged, but note that each time about 5 kg more should be applied than the previous time.

4. Spraying foliar fertilizer

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

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