Citrus water-soluble fertilizer application method

Abstract

The invention relates to a citrus water-soluble fertilizer application method. The method employs the following water-soluble fertilizer composed of the following components according to the followingrelationship: 4 g / L>=methyl jasmonate>=1g / L, 200 g / L>=(N+K2O)>=100 g / L, 30 g / L>=(B+Zn)>=15 g / L, 12 g / L>=atonik>=4g / L. Within 5 to 20 days after citrus fruits are harvested, the water-soluble fertilizer is diluted by 500 to 2000 folds for first foliar spraying; and after 10 to 14 days, secondary spraying is performed by employing a same process, wherein the weight ratio of the methyl jasmonate tothe atonik in the water-soluble fertilizer is 1:(1-5). The water-soluble fertilizer employed in the method of the invention can timely supplement nutrients demanded by reproductive growth of citrus, can strengthen the tree body after application, enhance photosynthesis, and strengthen full use of nutrients, nutrition production and delivery capacity, contributes to reproductive differentiation offruit trees, promotes balanced growth of leaves, flowers and fruits, changes the rate of male and female flowers, reduces fruit shedding, and has effects of strengthening flowers and protecting fruits.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for applying citrus water-soluble fertilizer. Background technique [0002] Citrus is one of the main fruit varieties planted on a large scale in Guangxi. 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 and other nutrients The ingredients have become a must-have precious fruit for people during the Chinese New Year. In Guangxi, the main citrus varieties such as Shatangju, Wogan, Mashuiju, etc. are generally harvested from December to the end of February of the second year, and the period of reflowering will come shortly after harvesting, so the interval from harvesting to flowering Short, resulting in insufficient vegetative growth of fruit trees, the difficulty of subsequent fruiting increases, so that if a high yield is obtained in the ...

Problems solved by technology

In Guangxi, the main citrus varieties such as Shatangju, Wogan, Mashuiju, etc. are generally harvested from December to the end of February of the second year, and the period of reflowering will come shortly after harvesting, so the interval from harvesting to flowering short, resulting in insufficient vegetative growth of fruit trees, and increased difficulty in subsequent fruiting, so that if a high yield is obtained in the first year, there will be less fruit in the second year, and the fruit trees cannot be stable and stable, affecting the economic income of farmers

[0003] In order to supplement nutrients to fruit trees in time, fruit growers choose to supplement foliar fertilizers after harvesting citrus. However, spraying foliage fertilizers that only contain nutrient elements alone cannot regulate the physiological functions of fruit trees in all aspects and promote the normal growth of fruit trees. blossom and bear fruit
