1、How to use boron fertilizer in rapeseed field

Boron fertilizer generally has two methods: base application and foliar application: 1. Ke Shi: The main supply of borax and ten element boron fertilizer in Ningbo Agricultural Market is the main method of applying borax.

2、不同硼肥用量对油菜产量与养分含量的影响

Excessive amount of boron fertilizer is not conducive to the absorption of nitrogen, phosphorus and potas-sium nutrients in rapeseed. Based on the above studies, it is recommended that the applicable amount of boron fertilizer in rape production in this region is 7.5 kg/hm2.

3、High

The application of boron fertilizer is an indisputable fact to promote the increase of rapeseed. Especially the application of boron fertilizer in soils with severe boron deficiency is more significant. The practice of many years has proved that the increase is 20%, and the increase is more than 30%.

Spring Application Tips for Boron Fertilization

Boron can be applied in bulk fertilizer applications with other macro- and micronutrient application. But because boron application rates are low when compared to macronutrients, you must assess the product spreadability in order to achieve uniform field application.

Pay attention to boron supplement in rapeseed

Therefore, special attention should be paid to the application of boron fertilizer to the drought-bearing rapeseed. Even if rapeseed fields with boron fertilizers have been applied at the time of sowing or transplanting, foliar spraying of boron is still required during flowering.

Rape boron fertilizer application technology

The application of boron fertilizer in rapeseed should be prior to the flowering period to ensure the maximum demand for boron nutrition from the growth and development of rapeseed from flowering stage to pod stage.

Rational application of boron fertilizer on rapeseed

Control measures: It is necessary to strictly control the age of the seedlings, and it is best to control the temperature of the seedlings without controlling the water.

Rape science boron application technology

1. Foliar application. Since boron is the most difficult element to move in the plant, the effect of spraying boron on the foliage is the best. The test results show that the key period of boron application is seedling stage, flood season and flowering stage.

How to Apply Boron Fertilizer? The Ultimate Guide

To prevent boron toxicity, it is crucial to follow recommended application rates, avoid applying boron fertilizer to wet soils, and ensure proper soil drainage.

Boron Application Timing: Insights from Lee Lubbers & US Borax

Lee Lubbers discusses the crucial timing for boron application, its soil dynamics, and the strategies for optimal boron levels with Wendall from US Borax at Commodity Classic.

Applying boron fertilizer to rapeseed is one of the most important measures to improve its yield and quality. Boron plays a crucial role in the growth, development, and stress resistance of rapeseed. Proper application of boron fertilizer can promote root development, enhance the plant's stress resistance, and improve both yield and quality. Below are recommendations for the timing and methods of applying boron fertilizer to rapeseed:

1. Timing for Applying Boron Fertilizer

(1) Seedling Stage

Rapeseed grows rapidly during the seedling stage. Applying boron fertilizer at this stage can promote root development and strengthen the plant's disease resistance. Generally, boron fertilizer should be applied 7-10 days after sowing, when the young plants have grown 2-3 true leaves.

(2) Bud Stage

The bud stage is a critical period for rapeseed growth and development. Applying boron fertilizer at this stage can promote pollen formation and pollination, improving yield and quality. Typically, boron fertilizer should be applied 10-15 days before flowering.

(3) Maturation Stage

The maturation stage is the final phase before harvest. Applying boron fertilizer at this stage can promote seed maturation and improve seed quality. Generally, boron fertilizer should be applied 20-30 days before maturation.

2. Methods for Applying Boron Fertilizer

(1) Basal Application

Mix boron fertilizer evenly with the soil and spread it directly around the roots of the rapeseed plants. This method is suitable for large-scale planting.

(2) Ditch Application

Dig ditches between rapeseed rows, spread the boron fertilizer evenly in the ditches, and then cover the soil. This method is suitable for small-scale planting.

(3) Slot Application

Dig slots between plants, spread the boron fertilizer evenly in the slots, and then cover the soil. This method is suitable for home gardens or small farms.

3. Precautions

(1) Timing

The timing of boron application should be based on the growth stage of rapeseed to avoid missing the optimal period.

(2) Method

The application method should be chosen according to soil conditions and plant growth status to ensure effective absorption and utilization of boron.

(3) Dosage

The amount of boron fertilizer should be determined based on the growth stage and soil fertility to avoid waste or environmental pollution caused by excessive application.

(4) Frequency

The frequency of application should be adjusted according to the growth stage and soil conditions to ensure normal plant development.

applying boron fertilizer is a key measure to improve rapeseed yield and quality. By mastering the timing and methods of boron application, farmers can effectively promote rapeseed growth and development, ultimately achieving higher yields and better quality.
