Rice plant quality cultivating tray and preparation method thereof

Technical field

[0001] The present invention belongs to agricultural production materials and a preparation method thereof, and relates to a rice plant material, a raw material and a manufacturing technology for rice seedlings and planting. Background technique

[0002] At present, the seedling trays used in agricultural production include plastic trays, pulp trays, and resin trays. Plastic trays are available in a variety of order, but no matter which form can be directly inserted into the machine, manual or double transplanting is required. It takes time and labor, and the seedlings are poor and easy to float. The pulp tray is used. The papermaking process is formed by adsorption, and the cost is low, but the wet strength of the pulp pan is low, and the pulping is excessively rotted at the end of the nursery period, and the machine insertion cannot be realized; the resin pan, the seedling quality is good, and the mechanical planting can be realized, due to the machine structure It is very complicated, with high processing precision, large investment, and expensive resin trays, which is difficult to promote and apply. Plastic trays and resin trays have poor water retention and require repeated watering and waste of water resources. Plastic trays and resin trays need to be recycled and carefully stored to increase management costs. Summary of the invention

[0003] The object of the present invention is to solve the problems of the prior art mentioned above, and to invent a rice plant material breeding tray composed of a plant material as a main component and a preparation method thereof, which can be degraded or combined with Rice seedlings and alfalfa blocks are planted in paddy fields to achieve nutrient-rich, rice seedlings planted in paddy fields without slow seedling stage, which is conducive to crop growth, fertility, and reduced production and manufacturing costs.

[0004] The object of the present invention is as follows: The rice plant material cultivating tray manufacturing material is composed of straw powder, water-soluble biological latex, micro-fertilizer nutrient medium soil, nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, fungicide and acid regulating agent. Percentage by weight of each component is: straw powder 55-60%, water-soluble bio-later 2-030%, micro-fertilizer nutrient medium 10-15%, nitrogen fertilizer 3-4%, phosphate fertilizer 2-3%, potassium fertilizer 2 -3%, bactericide 0.1-0.5%, acid regulator 0.2-0. 4%. The micro-fertilizer nutrient medium soil is composed of high-quality peat soil and multi-active formula trace elements in the following weight ratios: high quality peat soil: magnesium: sulfur: iron: boron: copper: manganese: zinc: molybdenum: chlorine = 9.7: 0.02: 0.015: 0.075: 0.030: 0.042: 0.037: 0.048: 0.007: 0.026.

[0005] The preparation process of the rice plant quality cultivating tray as described above is:

[0006] 1, the straw straw is pulverized by a pulverizer having a sieve opening diameter of 2-3 metre, and then made into a straw powder for use;

[0007] 2, the straw powder and the water-soluble biological latex are mixed and stirred, and then the nitrogen fertilizer, the phosphate fertilizer, the potassium fertilizer, the micronutrient nutrient medium soil are put into the above mixture and stirred uniformly, and finally the fungicide and the acid regulating agent are placed. Mixing and mixing in the material to obtain the material for preparing the rice planting tray; [0008] 3, in the preparation of the preparation of the material, the rice planting seedling tray forming mold is heated to 100-120;

[0009] 4, weigh the weight of the preparation material required to manufacture each rice plant cultivating tray, and fill it into the preheated forming mold, and hold the mold for 4-6 minutes;

[0010] 5, open the molding die, exit the rice plant quality 钵秧 tray;

[0011] 6, the rice plant quality cultivating tray drying, shaping, bundling, complete rice planting 钵秧。。。.

[0012] The plant quality cultivating tray is prepared by using straw powder as a main raw material, adding nutritive additives and sterilization sterilizing agents necessary for rice growth, and processing. The new plant quality cultivating tray has high water resistance, rich in slow-release organic fertilizer required for rice growth, good molding performance, sufficient soil, good water retention, easy packing, and formation of clams. Satisfying the requirements of mechanical planting, it can breed the scorpion scorpion with scorpion, and the seedlings in the planting are not wilting, and the root system can be kept intact without slow seedling period. The seedlings and clams are planted in the field at one time. The clams slowly degrade in the rice field with the growth of rice, providing nutrients for rice growth, and at the same time, fertilizing the soil to prevent land compaction and finally returning rice straw to the field. The plate is low in cost and easy to manufacture.

detailed description

[0013] The invention will now be described in detail by way of examples.

[0014] The straw straw was pulverized by a pulverizer having a sieve opening diameter of 25 mils to prepare straw powder for use.

[0015] Weigh 57 kg of straw powder, 22 kg of water-soluble bio-milk, 12 kg of micro-fertility nutrient medium, 3.5 kg of nitrogen fertilizer, 2.5 kg of phosphate fertilizer, 2.4 kg of potassium fertilizer, 0.3 kg of fungicide and 0.3 kg of the acid modifier was used, and the percentage of each component in the total weight was 57%, 22%, 12%, 3.5%, 2.5%, 2.4%, 0.3%, and 0.3%. Among them, 12 kg of micronutrient nutrient medium soil is taken from 19.4 kg of high quality peat soil, which in turn is 0.04, 0.03, 0.15, 0.06, 0.084, 0.074, 0.096, 0.014, 0.052 kg of magnesium, sulfur, iron, boron, copper. 20 kg of micronutrient nutrient medium soil composed of manganese, zinc, molybdenum and chlorine.

[0016] 57 kg of straw powder and 22 kg of water-soluble bio-milk were mixed and stirred, and then 3.5 kg of nitrogen fertilizer, 2.5 kg of phosphate fertilizer, 2.4 kg of potassium fertilizer and 12 kg of micro-fertilizer nutrient medium soil were added together. The mixture of the straw powder and the water-soluble biological latex is evenly stirred. Finally, 0.3 kg of the bactericide and 0.3 kg of the clarifying agent are placed in the above mixture to stir the hook, thereby obtaining the material for the rice plant cultivating tray. While preparing the material, the rice planting cultivating tray forming mold is heated to HO; the preparation material is weighed according to the weight of the preparation material required for each tray, and filled into the boring mold, and the pressure is kept after the mold is closed. After about 5 minutes, the mold is opened, the rice plant cultivating tray is taken out, and the rice plant cultivating tray is dried, shaped and bundled to complete the production of the rice plant cultivating tray.

[0017] The scientific research test data shows that the plant quality cultivating tray can save 60% of the seed and save 40% of the soil for breeding compared with the ordinary mechanical transplanting tray. Due to the small amount of seeding, the area occupied by the individual is far greater than that of the common machine seedlings, which is conducive to the cultivation of large and strong seedlings, and the quality of the seedlings is better than that of ordinary machine insertion seedlings. [0018] Comparison of seeding rate, single seedling area and seedling quality of different seedling methods

[0019] It can be seen from the table that in the same period of sowing, 30 days old, the leaf age, dry weight and fullness of the seedlings are far greater than the seedling seedlings, indicating that the seedling quality of the seedlings is better than the machine insert. Nursery. Therefore, the early birth is good, 5-7 days earlier than the ordinary machine inserted in the seedlings, and the dryness is significant, the degree of fullness is high, the early birth is good, and the earing is earlier than the ordinary machine.

[0020] The roots are continuously rooted when planted, and there is no plant injury. The investigation showed that the survival rate of alfalfa roots after transplanting by ordinary machine inserts was only 12.7%, while the survival rate of alfalfa roots after planting seedlings was up to 42.9%. Therefore, the seedlings were not planted. The tillers occur early and the early growth is strong. Planting with alfalfa, less plant damage to the roots. Therefore, the effect of increasing production is obvious, and the average mu increase is 20-25%.
