What fertilizer is best for growing rapeseed? What fertilizer is best for growing rapeseed to get high yield?

If we want to grow rapeseed with a better yield, we must grasp the right season for fertilization. Before winter comes is the key to high rapeseed yield. It is best to use two-thirds of a bag of nitrogen fertilizer supplemented with phosphorus, potassium and boron fertilizers as base fertilizers for rapeseed. In this way, strong seedlings can be obtained, and if boron fertilizer is applied as a base fertilizer, there is no need to apply topdressing at the seedling stage.

Fertilizer for rapeseed

Rapeseed itself is a fertilizer-loving plant, so before planting rapeseed, it is necessary to apply sufficient base fertilizer to prevent the rapeseed from lacking fertilizer during its development. So what kind of fertilizer is suitable for planting rapeseed?

1. Farmyard manure

Generally, we can choose farmyard manure with sufficient nutrients, which not only contains common elements such as nitrogen, phosphorus, potassium, etc. It also contains trace elements such as sulfur and zinc that are necessary for the growth of rapeseed, which is beneficial to the growth and development of rapeseed and is not easy to cause soil compaction.

2. Ecological fertilizer

When plowing the field, applying compound microbial ecological fertilizer throughout the field can not only increase the content of soil organic matter, but also improve soil permeability. After making ridges, rapeseed seeds are sown directly.

3. Compound fertilizer

After the rapeseed seedlings have emerged and thinned out, add microbial agents and chlorine-based compound fertilizer to water and use as seedling fertilizer to water the roots of the rapeseed seedlings. In addition, during the winter, chlorine-based compound fertilizer can be used as winter fertilizer and spread throughout the field.

4. Nutrient solution

In order to improve the cold resistance of rapeseed, and in combination with preventing aphids and cabbage loopers, you can use the Polyenergy Tiger Amino Acid Chinese Herbal Nutrient Solution to spray the leaves once.

In addition, in early spring, when rapeseed begins to sprout, combine disease and insect prevention and flower-but-unfruit prevention with foliar spraying of Feitianhu Chinese herbal nutrient solution 1-2 times.

Rapeseed Fertilization Method

1. Fertilization principles

The principle of fertilizing rapeseed is to use basal fertilizer as the main fertilizer, and then apply nitrogen, phosphorus, potassium and boron fertilizers in the sowing or transplanting furrows. Topdressing should be "early, heavy, steady and skillful". Try to apply seedling fertilizer early before the New Year, apply winter fertilizer heavily, apply stalk fertilizer steadily, and apply flower fertilizer skillfully to achieve high yield and high quality.

2. Key points for fertilizer selection

For rapeseed growing on medium-fertility soil, less potassium fertilizer should be used. The amount of nitrogen fertilizer applied should not be too little, but too much nitrogen should not be applied either, so as to avoid attracting diseases and pests. More phosphorus, potassium and boron fertilizers should be applied appropriately.

Generally, the fertilization of high-quality rapeseed should pay attention to the combination of phosphorus and potassium fertilizers, and the combination of chemical fertilizers and farmyard manure. This is an important fertilization principle. Boron fertilizer is applied at a rate of 0.75 kg per mu . It can be sprayed on the leaves. Add 100 grams of borax to every 50 liters of water and mix well. This can increase the fruiting rate of rapeseed and increase yield.
