Embodiment
As illustrated in fig. 1 and 2; Do not have native organic paddy rice seedling dish body and comprise top tray layer (1) and following pallet layer (2) by organic materials compression moulding; Be provided with fertilizer layer (3) between top tray layer (1) and the following pallet layer (2), top tray layer (1), following pallet layer (2) and fertilizer layer (3) are combined into one through hot pressing.
Said seedling dish body is provided with some evenly grooves (4) of sowing of being convenient in the dish inner surface.
Said seedling dish body is provided with reinforcement (5) in dish edge inwall place all around.
Processing method comprises the steps:
A, pulverizing: foreign material are pulverized and removed to the peat composed of rotten mosses;
B, pulping: by weight, the paper pulp of the peat composed of rotten mosses of 70 ﹪~80 ﹪ and 20 ﹪~30 ﹪ is added water break into pulpous state;
C, moulding: upper and lower layer blank processed in the finished product slurry dehydration moulding that stirs;
D, oven dry: the blank dehydration back oven dry after the moulding;
E, compound:, be combined into one through hot pressing with dosing fertilizer between the upper and lower layer blank;
F, shearing packing: the semi-finished product after compound are sheared back packing, finished product.
Said fertilizer is fertilizer or chemical fertilizer or the mixture of the two.
Said fertilizer accounts for 5%~15% of the peat composed of rotten mosses and paper pulp total amount.
Add adhesive in the said step b pulping process, 0.2%~1% of the binder constitutes peat composed of rotten mosses and paper pulp total amount.
Embodiment 1:
By weight, the paper pulp of the peat composed of rotten mosses of 75 ﹪ and 25 ﹪ is added water and break into pulpous state; Add 0.2%~1% of the binder constitutes peat composed of rotten mosses and paper pulp total amount; Upper and lower layer blank processed in finished product slurry dehydration moulding; With dosing fertilizer between the upper and lower layer blank, be combined into one through hot pressing; Fertilizer accounts for 5% of the peat composed of rotten mosses and paper pulp total amount.
This products material mainly comprises the peat composed of rotten mosses, paper pulp (available waste paper making beating), fertilizer and adhesive.The selection of adhesive is the key that product forms, and mainly at the enterprising row filter of plant resource adhesive, can confirm 5 plant species adhesives (wheat, corn, paddy rice, potato and ground melon starch) at present, can emerge safely.Proportioning: by weight, the peat composed of rotten mosses is 70%~80%; Paper pulp is 20%~30%, and fertilizer accounts for 5%~15% of the peat composed of rotten mosses and paper pulp total amount, 0.2%~1% of the binder constitutes peat composed of rotten mosses and paper pulp total amount.
As long as at suitable nursery stage, this product can not grown seedlings by the weather and the influence of the situation that fetches earth at any time.Conventional rice is grown seedlings needs preparation nutrition soil, fetch earth and transport soil back after also need sieve soil, add fertilizer or rice seedling-growth soil regulator again and mix in soil, sabot then, balance and carrying, the operational sequence of growing seedlings is loaded down with trivial details.Need not fetch earth, mix soil with this product, need not add fertilizer or rice seedling-growth soil regulator, not need sabot, convenient transportation yet.Simplify the program of growing seedlings, alleviated labour intensity simultaneously.The conventional rice grow seedling nutritional adopts rice seedling-growth soil regulator or chemical fertilizer, and nutrition is inorganic nitrogen, phosphorus, potash fertilizer.And this product itself is exactly organic matter and biological organic fertilizer, and both environmental protections increase the soil organic matter again, improved soil.
Not having native organic paddy rice seedling dish can directly degrade, and increases the soil organic matter.This product has replaced seedbed soil, plastics machine transplanting of rice dish and the required fertilizer (rice seedling-growth soil regulator) of growing seedlings fully; Seedbed weed killer herbicide and seedling bed regulating acid agent have been saved.Reduce and prevent that Miao Qi Celadon is withered, the dosage and the medication number of times of damping off.The seedling quality that uses " not having native organic paddy rice seedling dish " to cultivate is good, well developed root system, and than long 3~5 centimetres of conventional nutrition seedlings and soil root, many 2~3 of root system number, each item index all is superior to conventional nutrition seedlings and soil.Show as many, the Gen Sebai of radical, Miao Sezheng, growth is neat, is suitable for machine rice transplantation.This product is in the seedling process, and seedling bed temperature is higher 1.0~2.0 ℃ than conventional seedling bed temperature; Than conventional bed seedlings and soil quick heating, become seedling Zao, can emerge ahead of time 1~2 day, turn green 2~3 days, premature ripening can shift to an earlier date rice transplanting 3~5 days in advance.Use this product operation simple, saving of work and time.Be suitable for three-dimensional seedling raising and industrial sprout cultivation.
