Alginic acid containing water-soluble fertilizer for oranges

Abstract

The invention relates to an alginic acid containing water-soluble fertilizer for oranges. The water-soluble fertilizer comprises the following ingredients by content: alginic acid with the concentration of not smaller than 20g / L and not greater than 80g / L, N+K2O with the concentration of not smaller than 100g / L and not greater than 200g / L, B+Zn with the concentration of not smaller than 15g / L and not greater than 30g / L, and sodium nitrophenolate with the concentration of not smaller than 4g / L and not greater than 12g / L. The water-soluble fertilizer can be used for supplementing all nutrients required for the reproductive growth of the oranges in time; after the water-soluble fertilizer is applied, the water-soluble fertilizer can be used for strengthening trees, enhancing photosynthesis and strengthening the full utilization of the nutrients, nutrition manufacturing and delivery capacity; the water-soluble fertilizer is conductive to the reproductive differentiation of fruit trees, the balanced growth of leaves, flowers and fruits is promoted, the ratio of female and male flowers is changed, the falling of fruits is reduced, and thus, the water-soluble fertilizer has the effects of strengthening the flowers and protecting the fruits.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a citrus water-soluble fertilizer containing alginic acid. Background technique [0002] Shatangju is one of the main fruit varieties planted on a large scale in Guangxi this year. It is loved by people because of its delicious taste and rich nutrition. Its juice is rich in citric acid, amino acids, carbohydrates, multivitamins, calcium, phosphorus, iron Nutrients such as fenugreek have become a must-have precious fruit for people during the Chinese New Year. In Guangxi, the sugar oranges are generally harvested from December to the end of January of the next year, and usually re-bloom in February; therefore, the time interval from harvest to re-flowering is relatively short, resulting in insufficient vegetative growth period of the fruit tree itself, and subsequent flowering The difficulty of fruiting increases, so that if a high yield is obtained in the first year, there...

Problems solved by technology

In Guangxi, the sugar oranges are generally harvested from December to the end of January of the next year, and usually re-bloom in February; therefore, the time interval from harvest to re-flowering is relatively short, resulting in insufficient vegetative growth period of the fruit tree itself, and subsequent flowering The difficulty of fruiting increases, so that if a high yield is obtained in the first year, there will be less flowering and fruiting in the second year, and the fruit trees will not be able to produce and harvest stably, which will affect the economic income of farmers

[0003] Generally, fruit growers supplement fruit tree nutrient fertilizers in time after the sugar orange is harvested, and generally supplement various elements required for the reproductive growth process of fruit trees by spraying foliar fertilizers. However, spraying foliar fertilizers that only contain nutrient elements alone cannot It can well regulate the physiological functions of all aspects of fruit trees and promote the normal flowering and fruiting of fruit trees
