Which type of foliar fertilizer is best for rice?

Rice is one of the crops that requires more fertilizer. In addition to base fertilizer and top dressing, many farmers also use foliar fertilizer in pursuit of high yields. Rice foliar fertilizer plays an important role in increasing rice yield, improving quality, promoting rice metabolism and improving the ability to resist adversity. So which type of foliar fertilizer is best for rice? Let’s learn more about it below.

Which type of foliar fertilizer is best for rice?

Rice has different requirements for nutrients in different growth stages. The choice of foliar fertilizer should be determined according to the specific needs and growth conditions of rice, so that the best effect can be achieved. Usually, urea, potassium dihydrogen phosphate, superphosphate, potassium sulfate and some soluble micro-fertilizers are suitable for rice foliar fertilizers.

How to use rice foliar fertilizer?

1. Determine the spraying period

(1) Tillering stage: The tillering stage of rice is generally 45 days after sowing. At this time, spraying foliar fertilizer can promote the growth of low-node tillers and play a role in increasing the number of ears.

(2) Heading stage: When rice begins to head and the young panicles are about 1 cm long, it is the basic period for ear formation and grain development. Spraying foliar fertilizer helps control ineffective tillering.

(3) Grain stage: From heading to maturity, foliar fertilization can quickly increase the weight of rice grains and improve yield.

2. Dilute fertilizer

Strictly dilute according to the recommended ratio on the foliar fertilizer product instructions. The dilution ratio may vary for different products and different growth stages.

3. Spraying method

Choose a windless, cloudy day or sunny morning for spraying, and avoid spraying on hot or rainy days. Use a sprayer to evenly spray the foliar fertilizer solution on the rice leaves, especially the back of the leaves, to improve absorption efficiency.

4. Spraying times

Determine the number of spraying according to the growth of rice and the specific effect of foliar fertilizer. Usually foliar fertilizer can be sprayed 2-3 times throughout the rice growing season.

5. Notes

(1) If it rains after spraying, you may need to spray again.

(2) Avoid mixing with other pesticides or fertilizers unless it is ensured that there will be no chemical reaction between them.

(3) Avoid high temperatures and strong winds when spraying to reduce evaporation and drift of the fertilizer solution.

In general, correctly spraying rice foliar fertilizer can give full play to the characteristics of rapid absorption of foliar fertilizer and ensure the normal growth and development of rice under suitable fertilizer and water conditions. It is one of the important measures to improve quality and increase yield.
