Problems solved by technology

However, when ordinary quick-acting fertilizers are applied to the substrate, their nutrient validity period is generally short and they are easy to lose with water, so they cannot continue to meet the nutrient supply in the later stage of the 80-100-day seedling cycle, and the late topdressing also has problems such as time-consuming and labor-intensive problems.

Embodiment 1

[0033] according to figure 1 The shown process is to prepare a special slow-release matrix for eggplant seedlings:

[0034] Mix the peat, vermiculite, and perlite according to the volume ratio of 1:1:1 to obtain the basic matrix, and then mix and add the urea formaldehyde, ammonium polyphosphate, and humic acid materials (fineness of 10 to 60 mesh, respectively, 3%, 2% and 3% of the base matrix mass), supplemented with 0.5% quick-acting compound fertilizer of the base matrix mass. After mixing, the matrix is ​​evenly moistened with 3% water of the base matrix mass and diluted 50 times with chlorothalonil After spraying on the substrate for sterilization, and fully mixing, a special slow-release substrate for eggplant seedlings with comprehensive and balanced nutrients is obtained, which can ensure a balanced and continuous supply of nutrients during the eggplant seedling stage (80-100 days). The specific test design is as follows: The tested variety is Kuaiyuan Eggplant (the fru...

Embodiment 2

[0036] Mix the peat, vermiculite, and perlite according to the volume ratio of 1:1:1 to obtain the basic matrix, and then mix and add the urea formaldehyde, ammonium polyphosphate, and humic acid materials (fineness of 10 to 60 mesh, respectively, 4%, 4% and 3% of the base matrix mass), supplemented with 0.5% quick-acting compound fertilizer of base matrix mass. After mixing, evenly wet the matrix with 5% water of the base matrix mass, and dilute with formaldehyde solution 50 times Sprayed on the substrate for sterilization, fully mixed, extruded by a mechanical extruder at a pressure of 0.5Mpa to prepare a special slow-release substrate module for eggplant seedlings with comprehensive and balanced nutrients. It has good water and fertilizer retention capabilities and is suitable for eggplant seedling growth. It can ensure a balanced and continuous supply of nutrients at the eggplant seedling stage (80-100 days); especially the eggplant seedlings produced by the substrate block ...

Abstract

The invention discloses a sustained-release culture medium for eggplant seedling culture and a preparation method thereof. The preparation method includes: mixing turf, vermiculite and perlite according to a certain proportion, adding urea formaldehyde, ammonium polyphosphate and humic acid according to a certain proportion and mixing, adding a small amount of quick-acting fertilizer to serve as the auxiliary material, mixing and evenly wetting the medium with an appropriate amount of water, adding substances such as common bactericides, and sufficiently mixing to obtain the sustained-releaseculture medium which is comprehensive and balanced in nutrients and specially used for eggplant seedling culture. The sustained-release culture medium has the advantages that nutrient balance and continuous nutrient supply in the seedling period (80-100 days) of eggplants can be guaranteed; meanwhile, a sustained-release culture medium module special for eggplant seedling culture can be prepared through mechanical extrusion, and the sustained-release culture medium module is good in water-retaining and fertilizer-retaining ability and suitable for eggplant seedling growth.

Description

Technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a special slow-release matrix for eggplant seedling raising and a preparation method thereof. Background technique [0002] Eggplant is one of the common and well-loved vegetables. It is rich in protein, fat, vitamins, carbohydrates, phosphorus, iron, calcium and other nutrients. [0003] When eggplant is cultivated in early spring, whether it is produced in a protected area or in the open air, most of the seedling age requires 80-100 days; at the same time, when the seeds are cultivated in a seedling substrate, sufficient and comprehensive nutrients are needed to supply crop growth. According to the law of plant nutrition, the critical period of crop nutrition refers to the period when a certain nutrient deficiency, excessive or improper ratio has the greatest impact on the crop; this period mostly occurs in the early stage of crop growth, and the same is true for eggplant seedling...
