Embodiment 1
[0033] The water-resistant degradable plant nutrient sustained-release material of this embodiment is prepared as follows:
[0034] (1) Weigh 20 g of corn starch into 5 g of distilled water, then add 12 g of citric acid and 8 g of glycerin, stir evenly and then stand for 24 hours to obtain modified corn starch.
[0035] Add 45 g of modified corn starch to 10 mL of distilled water to prepare a starch solution; put the starch solution in a three-necked flask and stir while heating at 95°C for 0.5 h to obtain gelatinized starch;
[0036] Weigh 5 g of PVA, add 1.25 g of distilled water, heat to dissolve at 97°C, and cool the resulting solution to 80°C to prepare a PVA solution.
[0037] Add the PVA solution to the gelatinized starch, and then stir while heating at 95°C for 0.5h, and the resulting product is cooled to below 80°C to obtain the binder;
[0038] (2) Measure 2mL of glacial acetic acid in a 100mL volumetric flask, dilute with distilled water to make the volume; add 2g of chitosan...
Embodiment 2
[0045] In this example, the nutritional sustained-release material was prepared in the same manner as in Example 1, except that the volume of the porogen DBP in step (3) was 12 mL.
[0046] The scanning electron micrograph of the porous composite microspheres obtained in this example is as follows figure 1 (b) Shown.
Embodiment 3
[0048] In this example, the nutritional sustained-release material was prepared in the same manner as in Example 1, except that the volume of the porogen DBP in step (3) was 16 mL.
[0049] The scanning electron micrograph of the porous composite microspheres obtained in this example is as follows figure 1 (c) and figure 2 (a) Shown.
