There is a great demand for fertilizers in the growth period of taro, among which potassium fertilizer is the most needed, but chlorine-containing fertilizers cannot be used. Usually, decomposed organic fertilizer and compound fertilizer are the main fertilizers applied in spring. Taro is a potassium-loving crop. Generally, it is best to apply organic fertilizer, which can meet the nutrient demand of taro, promote its vigorous growth and improve fruit quality.

Increasing taro yield with fertilizer

In the later stage, topdressing should be carried out in the growth period and expansion period of taro. The main application of phosphorus and potassium fertilizers, such as 30-45 liters of ammonium bicarbonate and 40-50 liters of potassium dihydrogen phosphate per mu, can promote the growth and expansion of tubers.

Taro fertilized and blossomed.

When taro blooms in 2008, it usually absorbs nutrients from taro stems, resulting in a decrease in yield, smaller fruits and lower starch content. So in Taro's daily life,

Taro fertilization time

Seedling stage: spraying foliar fertilizer on taro at seedling stage can break the dormancy period of seeds and germinate and grow as soon as possible. The specific application method can soak the diluted fertilizer solution and cultivate it to improve the resistance of taro to various diseases in the soil. Tuber expansion period: During tuber expansion period, plants grow vigorously and have strong photosynthesis, so they need enough fertilizer and water. Try to add fertilizer before changing heads in June to prevent drought and rain. Foliage fertilizer was applied in these two stages and sprayed every 10- 15 days.

Fertilization method of taro

1. No fertilization or fertilization is applied for about 15 days in the early stage of taro cultivation. Excessive fertilization not only wastes fertilizer, but also affects the development of crop roots and even causes fertilizer damage. It is necessary to ensure that an appropriate amount of nitrogen fertilizer is applied after the young roots begin to grow. 2. When the temperature is normal in the early stage of cultivation, in order to promote the sound development of young roots, it is suggested to apply proper amount of root elements to taro in time to form a complete root group in advance, so as to provide nutrient absorption for taro.
