Technical field
The present invention relates to the viscous of planting technology field more particularly to a kind of addition modified urea-formaldehyde resin for cucumber seedling-raising
The preparation method of mould assembly matrix.
Background technology
Culturing and transplanting seedlings can be such that early ripening of the crops, high yield, high-quality, saving resource, protected crop about more than half needs
Carry out nursery.The planting patterns of traditional culturing and transplanting seedlings relies primarily on manual work, time-consuming, inefficiency, therefore machine
Tool transplantation technique has obtained development energetically.Machinery transplanting can guarantee spacing in the rows, line-spacing, the depth of transplanting.However, existing market
On seedling medium be fetched into from seedling culture hole plate be moved to ground after earthing mechanization transplanting during, due to manipulator
The improper and mechanical physical vibration of grasping force, seedling medium have it is different degrees of be scattered, to cause root system damage,
It is colonized phenomena such as ensuing crop transplanting seedling time is long.
It is scattered wound to solve mechanization transplanting process mesostroma, it is most of in the prior art to use pot for growing seedlings nursery, alms bowl
The degradation cycle of body is difficult to control, and substrate block is typically necessary compression forming, and is sticked together nursery using soil, by the soil that viscosity is larger
It suppresses, permeability is poor, and survival rate is low, is easily broken during watering and transplanting and hinders root.So in order to meet Huang
Problems faced during melon substrate seedling needs to develop a kind of nutrients release function that has both in the base of adhesiveness and one
Matter meets the needs of cucumber substrate seedling.
Invention content
The object of the invention is exactly to provide a kind of addition modified urea for cucumber seedling-raising to make up the defect of prior art
The preparation method of the adhesion type matrix of urea formaldehyde.

85-90 DEG C, 30-40 minutes are kept the temperature, to after cloud point, continues to adjust pH value of solution 7- with the potassium hydroxide solution of a concentration of 1mol/L
7.5, it is cooled to 70-75 DEG C, blowing after heat preservation 30-40 minutes obtains modified urea-formaldehyde resin；
（2）The kelp of the drying of wash clean is crushed respectively with Enteromorpha, 50 mesh sieve is crossed, then mixes according to a certain percentage
It closes, suitable water is added and is adequately infiltrated, complex enzyme is added, degradation 40-60 minutes is carried out at 40-45 DEG C, after degradation
Centrifugal filtration, concentration, spray drying, obtain kelp Enteromorpha extract；
（3）Original principle is uniformly mixed with suitable modified urea-formaldehyde resin, kelp Enteromorpha extract, is put into hole tray, is put into
60-65 DEG C of drying is molded for 3-4 hours in baking oven to obtain the final product.
A kind of preparation method of the adhesion type matrix of addition modified urea-formaldehyde resin for cucumber seedling-raising, step
（1）Described in urea, formaldehyde molar ratio be 1:1.2, the wherein additive amount of protein hydrolysate is the 8% of urea quality.
A kind of preparation method of the adhesion type matrix of addition modified urea-formaldehyde resin for cucumber seedling-raising, step
（2）Described in kelp and Enteromorpha adding proportion be 1:2.
A kind of preparation method of the adhesion type matrix of addition modified urea-formaldehyde resin for cucumber seedling-raising, step
（2）Described in complex enzyme refer to pentosan complex enzyme, additive amount 0.06%.

It is an advantage of the invention that：The present invention carries out enzyme after mixing kelp according to special composition proportion with Enteromorpha
Solution, available nutritional ingredient ratio is opposite to be increased, and nutrition is more balanced, and Mineral element content increases, and is added
Into the matrix of cucumber seedling, there can be facilitation to the growth of cucumber, crop yield can be improved, improving quality improves cucumber
To the resistivity of pest and disease damage and adverse circumstance, while the micro-ecological environment of matrix can also be improved；The present invention utilizes protein hydrolysate pair
Lauxite is modified, and obtains the modified resin with nitrogen slow releasing function, by itself and original principle, kelp Enteromorpha extract
It carries out compound, shapes under the action of high temperature, obtain the substrate block with nutrient controlled-release effect, and can pass through and regulate and control hydrolysis
The content of albumen regulates and controls the structure of modified urea-formaldehyde resin, and then regulates and controls nutrient release rate, so with the nutrient of cucumber seedling
Demand rule is almost the same, it is made to be conducive to the growth of cucumber root.Matrix prepared by the present invention has in modified urea-formaldehyde resin
When suitable additive amount, compression strength is good, disclosure satisfy that the requirement of manipulator crawl, also disclosure satisfy that cucumber seedling root growth
