Description

Technical Field

[0001] The invention relates to the technical field of rice seedling raising trays, and in particular to a split combined full-nutrition straw rice seedling raising tray and a processing method thereof. Background Art

[0003] At present, the existing rice seedling raising technology uses natural black soil and special fertilizer for seedling raising to mix and then put it into plastic seedling tray for seedling raising. However, there is no natural soil for seedling raising now, and it is difficult to get soil, which has become a major problem for farmers in rice seedling raising. Another technology is to use paper pulp and straw powder to make slurry, adsorb and shape it, and then dry and shape it to produce seedling trays. The disadvantage of the seedling tray produced by this technology is that the slurry is formed by water. The slurry must be adjusted first and then adsorbed and formed. The water must be removed when the slurry is formed. If the nutrients, fertilizers, bacteria, medicines, acids and trace elements needed by the seedlings are added to the slurry pool, they will be removed along with the water when the slurry is formed. Even if a small amount of fertilizer, bacteria, medicines, acids and trace elements remain in the seedling tray, the seedling tray will all evaporate when it is dried and shaped at high temperature. Therefore, this technology cannot add the fertilizer, bacteria, acid, medicine and trace elements needed for seedling growth when producing the seedling tray. Therefore, the quality of the seedlings is poor, the root system is underdeveloped, and they are prone to disease during seedling raising. Another disadvantage is that waste paper pulp must be added when producing seedling trays to prepare the pulp. Due to the high density of the pulp, the seedling trays are not breathable and watertight during seedling cultivation. It is not easy to irrigate them thoroughly in the early stage and they are prone to diseases in the later stage. Because this technology uses pulp to form seedling trays, the thickness is not enough. It does not retain water or fertilizer during the seedling period, resulting in weak seedlings with underdeveloped root systems, poor seedling rooting effects, and poor disease resistance. Another disadvantage is the high cost of pulp. The waste paper pulp contains a particularly high alkalinity, which is easy to burn roots and seedlings. It is particularly harmful to seedlings and difficult to cultivate seedlings. In addition, it is impossible to add fertilizer, bacteria, medicine, acid, and trace elements when producing seedling trays. The seedlings will lack fertilizer and medicine in the later stage, causing them to be unable to grow. The seedlings will become sick and die on a large scale, causing great economic losses to farmers. In the document (application number: 200810137207.8), a rice seedling tray and a preparation method thereof are disclosed, which mainly comprises the following steps: mixing straw powder and water-soluble biological latex, adding nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, and micro-fertilizer nutrient medium soil into the above-mentioned mixture and stirring evenly, and finally adding fungicide and acid regulator into the mixture and stirring evenly to obtain rice; when preparing the preparation material, the forming mold of the rice seedling tray is heated to 100-120° C. The weight of the preparation material required for manufacturing each rice seedling tray is weighed and filled into the preheated forming mold, and the mold is closed and pressure maintained for 4-6 minutes; the one-piece forming seedling tray, the water-soluble biological latex cost is relatively high, especially when it is used on a large scale, it will bring an economic burden, and the seedling tray also needs high-temperature forming, and the fertilizer, bacteria, medicine, acid, and trace elements in the seedling tray are easily evaporated when it is dried and formed at high temperature, resulting in poor seedling quality in the later stage, underdeveloped root system, and easy disease.

[0025] The material composition of the matrix seedling tray 2 is: straw fiber powder, nitrogen, phosphorus and potassium fertilizers, trace elements, carbendazim, sodium sulfamethoxam, myclobutrazol, paclobutrazol, and humic acid. 1 cubic meter of straw fiber powder is added with 2.5-5kg of nitrogen, phosphorus and potassium fertilizers, 2.5-5kg of trace elements, 0.2-0.5kg of carbendazim, 20-50g of sodium sulfamethoxam, 15-40g of myclobutrazol; 2-8g of paclobutrazol, and 5-10g of humic acid.

[0026] Nitrogen, phosphorus, potassium and trace elements are all the nutrients required by the seedlings during the growth period of the seedbed. The trace elements are commonly used elements such as magnesium, sulfur, iron, boron, copper, manganese, zinc, molybdenum, chlorine, etc., which are not limited in the present invention;

[0027] The chemical control drug paclobutrazol is used to control the excessive elongation of the stems of the seedlings, control leggy growth, prevent weak seedlings, and play a role in strengthening the seedlings;

[0028] The disease prevention drug is composed of sodium disulfide, azoxystrobin, and oxazolidinone, which can effectively prevent the occurrence of seedling diseases;

[0029] Humic acid plays a role in regulating the pH value of the seedling tray, because rice prefers acid to alkaline. Rice seedlings like to grow in acidic soil. If the soil is alkaline, the rice seedlings are prone to disease, because harmful bacteria like to reproduce in alkaline soil, so the seedlings are prone to disease;

[0030] The present invention can also add special biological agents (such as rhizobia, nitrogen-fixing bacteria, etc.) into the matrix seedling tray 2 to promote the growth and development of the seedling root system, so that the seedling root system is well developed in the seedling stage, the seedling can be resistant to disease and cold, the seedling can grow quickly after transplanting, the survival rate is high, the root is good and the seedling is strong, and the root is cultivated first.

[0034] S1. Processing of straw fiber powder: crush the straw and then inoculate it with fungi for fermentation. Cut the straw into coarse powder after two weeks of inoculation and fermentation, and then enter the secondary fermentation. After the straw is completely fermented, it is mechanically made into fiber powder. After the fiber powder is made, it enters the fine powder machine, and finally the straw fiber fine powder is dried to a moisture content of 20% to 25%;

[0035] S2. Batching: Add the processed straw fiber powder raw material into a batching machine for proportioning to prepare the split combined straw rice seedling tray raw material, proportion the types, add nitrogen, phosphorus and potassium, trace elements, mefenamic acid, sodium sulfamethoxam, azoxystrobin, paclobutrazol and humic acid to the straw fiber powder and mix them evenly;

[0036] S3, manufacturing: the prepared matrix seedling tray 2 raw materials are spread flat in the mold cavity and pressed at room temperature, and are formed only by pressure pressing. The formed matrix seedling tray 2 enters the intelligent conveyor, and two groups of matrix seedling trays 2 are simultaneously loaded into the degradable plastic chassis 1 through the suction cup of the intelligent conveyor.
