Embodiment 1
[0034] The anti-bird protection device described in this embodiment includes a ring body 100 penetrating from top to bottom, and the ring body 100 can be degraded and returned to the field in 15-30 days under natural conditions. The annular body 100 is made of quicklime with a density of 1g / cm 3 The low-temperature incompletely carbonized silkworm excrement with a density of 1.3 g / cm 3 River sand, starch, K 2 HPO 4 After being uniformly mixed and formed by physical pressing, the ring body 100 has an inner diameter of 6-10 cm, a thickness of 0.6-1 cm, and a height of 10-20 cm.
[0035] In the field, CaO absorbs H from the air 2 O, generating Ca(OH) 2 , Ca(OH) 2 with K 2 HPO 4 Incomplete reaction, releasing part of K 3 PO 4 , intercepted CaHPO 4 , and finally returned to the field. Due to the large amount of CaO, the Ca produced at the end of the reaction 3 (PO 4 ) 2 , and finally returned to the field. The entire reaction process can last for 15-30 days, and the ...
Embodiment 2
[0050] What this embodiment describes is the preparation method of the anti-bird damage protection device described in the embodiment. Quicklime, low-temperature incompletely carbonized silkworm excrement, river sand, starch, K 2 HPO 4 Mix evenly according to the volume ratio of 4-8:8-12:4-6:4-8:1, and physically press and shape. More preferably, quicklime, low-temperature incompletely carbonized silkworm excrement, river sand, starch, K 2 HPO 4 According to the volume ratio of
[0051] Specific steps are as follows:
[0052] Step 1) Measure 80ml of quicklime and 80ml of 1g / cm 3 Low temperature incomplete carbonized silkworm excrement, 50ml1.3g / cm 3 River sand, 42ml starch, 10ml K 2 HPO 4 ;
[0053] Step 2) Take the measured quicklime, low-temperature incompletely carbonized silkworm excrement, river sand, starch, K 2 HPO 4 well mixed;
[0054] Step 3) Combine evenly mixed quicklime, low-temperature incompletely carbonized silkworm excrement, river sand, starch, K ...
