Problems solved by technology

[0004] Over the years, eggplant has mainly relied on a large amount of fertilizer and water input to increase production. Unreasonable irrigation and fertilization not only cause waste of water resources and fertilizers, but also lead to high incidence of eggplants, quality decline, and leaching of soil nitrate, lack of trace elements and environmental pollution.

Embodiment 1

[0056] A kind of special fertilizer for eggplant vegetative growth period and reproductive growth period,

[0057] The special fertilizer for the vegetative growth period is prepared from the following raw materials in mass percentage:

[0058]

[0059]

[0060] The special fertilizer for the reproductive growth period is prepared from the raw materials in the following mass percentages:

[0061]

[0062] The preparation method of the special fertilizer of above-mentioned eggplant vegetative growth period and reproductive growth period, its steps are:

[0063] A. First weigh the raw materials urea, dipotassium hydrogen phosphate, potassium nitrate, citric acid, ethylenediaminetetraacetic acid zinc salt, ethylenediaminetetraacetic acid iron salt, ethylene diaminetetraacetic acid, etc. Amine tetraacetic acid manganese salt, ethylenediamine tetraacetic acid copper salt, boric acid, sodium molybdate and water, and then mix the raw materials required for these special ferti...

Embodiment 2-9

[0072] Table 2 embodiment 2-9 the raw material ratio of eggplant reproductive growth period

[0073]

[0074] According to the nutrient absorption law of eggplant, it is concluded that the basic nutrient ratio of eggplant in the early growth period is determined as N:P 2 o 5 :K 2 O = 0.83: 0.36: 2.67 = 1: 0.427: 3.206, the basic nutrient ratio of eggplant in the late growth period is determined as N: P 2 o 5 :K 2 O=6.11:2.95:10.89=1:0.483:1.782. Considering the utilization rate of fertilizers in the current season, the utilization rate of N, P, and K of eggplant in this experiment is calculated to be 33%, 40%, and 60% respectively. :P 2 o 5 :K 2 O=1:0.352:1.763. The nutrient absorption ratio of eggplant in the late growth period is converted to the nutrient ratio of eggplant special fertilizer as N:P 2 o 5 :K 2 O=1:0.399:0.980. Two fertilizer formulas were obtained: 15-5.3-26.5 in the early growth period (vegetative growth period), and 20-8-19.6 in the late gro...

Abstract

The invention discloses a special fertilizer for eggplants in the vegetative growth phase and the reproductive growth phase, and an application method of the special fertilizer. The special fertilizer is prepared from urea, diammonium phosphate, potassium nitrate, citric acid, boric acid, sodium molybdate, water and trace elements; the special fertilizer is divided into two types, namely, a vegetative growth phase special fertilizer and a reproductive growth phase special fertilizer, and the two types of special fertilizers for the two growth phases are both specially designed according to the nutrient demand laws of the eggplants and the soil nutrient characteristics. The application method includes the following steps: applying the vegetative growth phase special fertilizer three times before flowering in the seedling stage according to the physiological characteristics, fertilizer requirement features and growth conditions of the eggplant in different growth phases; applying the reproductive growth phase special fertilizer once respectively in the first fruit phase, opposite sides fruit phase and four sides fruit phase of the eggplants, and totally six times of fertilizing are performed during the whole growth period. The special fertilizer provided by the invention is scientific and reasonable in formula, and the contained macroelements, medium elements and microelements correspond to the demands of the eggplants in the vegetative growth phase and the reproductive growth phase, so that the supply and demand are balanced; the application method is scientific and reasonable and can increase the yield of the eggplants and improve the quality of the eggplants.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and specifically relates to a special fertilizer for the vegetative and reproductive growth stages of eggplant, and also relates to a method for applying the special fertilizer for the vegetative growth and reproductive growth stages of eggplant, which is mainly applicable to fertilizer production enterprises and Eggplant planting areas provide enterprises with special fertilizer formula and production technology, and provide specific drip irrigation application concentration, time and application amount for eggplant growers. Background technique [0002] The National Twelfth Five-Year Plan clearly puts forward the direction and goal of resource conservation and environmental protection, strives to control non-point source pollution such as pesticides, chemical fertilizers and agricultural film, promotes agricultural water conservation and efficiency enhancement, strengthens the conservation a...
