Problems solved by technology

Fruit growers usually apply several kinds of chemical fertilizers randomly based on experience, and they cannot apply fertilizers scientifically. The ratio of nitrogen, phosphorus and potassium is out of balance, resulting in leggy jujube branches, low fruit setting rate, and serious pests and diseases. These fertilizers dissolve quickly in the soil, and the fertilizer effect time short, in the annual growth cycle of jujube trees, multiple fertilizations are needed to meet their nutritional needs, resulting in serious waste of fertilizers. The invention provides a special controlled-release fertilizer for jujube trees. Release, slow release of fertilizer effect

Abstract

The invention discloses a date tree specially-used release-controlled fertilizer which includes following raw materials, by weight, 80-90 parts of monopotassium phosphate, 40-50 parts of potassium nitrate, 50-60 parts of urea, 20-30 parts of formaldehyde, 60-70 parts of sunflower head powder, 1-2 parts of ferrous sulfate, 8-10 parts of chitosan, 15-20 parts of a fertilizer additive, 15-20 parts of bentonite, 0.002-0.004 parts of brassinolide and 10-15 parts of a fertilizer additive. The date tree specially-used release-controlled fertilizer is one-time applied before date tree sprouting in spring without dressing, is good in yield-increasing effect, is increased in utilization ratio and can save labor intensity and time.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a special controlled-release fertilizer for jujube trees and a preparation method thereof. Background technique [0002] Jujube is rich in nutrition, and it has been a good nutritional product for people to nourish since ancient times. Jujube has a long history of cultivation in my country. Reasonable fertilization is an important factor to increase jujube yield and improve jujube quality. At present, jujube trees are fertilized with urea, phosphate fertilizer and quick-acting compound fertilizer in addition to some organic fertilizers such as ring fertilizer and soil miscellaneous fertilizer. Fruit growers usually apply several kinds of chemical fertilizers randomly based on experience, and they cannot apply fertilizers scientifically. The ratio of nitrogen, phosphorus and potassium is out of balance, resulting in leggy jujube branches, low fruit setting rate, and serio...
