Embodiment Construction

[0014] Substrate preparation: mix peat, sandy black soil and vermiculite in a ratio of 2:1:0.5, add 0.25% of the total amount of the above-mentioned substances, and then mix evenly. The peat is the product of the formation and development of the swamp. The peat contains more than 75% of organic matter, about 30% of humic acid and fulvic acid, has small bulk density, good air permeability, rich in nitrogen, phosphorus, potassium and trace elements, pH The value is slightly acidic, which is very suitable for growing seedlings of crops; sandy black soil is a kind of soil with strong viscosity and rich in nutrients, and its function is mainly to facilitate the matrix to form lumps and provide certain nutrients; Siliceous minerals are made after high-temperature expansion, with small bulk density, large porosity, strong water absorption capacity, and contain more nutrients that can be absorbed and utilized by crops such as potassium, calcium, and magnesium. Diammonium phosphate is a...

Abstract

The invention relates to a substrate used in cotton cavity seedling transplantation and relative method, wherein said substrate is formed by mixed peat, black soil and vermiculite at 2:1:0.5, added with 0.25% ammonium phosphate. And the method for cavity seedling comprises that: wetting the substrate and putting into cavity disc with 176 cavities, compressing, seeding one grain into one cavity, covering vermiculite at 1.5cm, pouring water, putting disc into warm room, plastic booth or arc booth, grow seeding without irritating, irrigating water one time for 3-5 days in leaf period, irrigating water one time for 2-3 days in real leaf period, ventilating, moving substrate into large field when the seed old is 35-40day; in the process, feeding nourishment one time when the real leaf grows out that putting 2g ammonium phosphate into each cavity; 3 days before removing seed, putting rooting agent. With said invention, the survive rate is more than 98%, the seed period can reach 5-6days, the yield can increase 10%.

Description

【Technical field】 [0001] The invention relates to a technique for growing and transplanting cotton seedlings, in particular to a substrate and a method for growing and transplanting cotton seedlings, in particular to a substrate and a method for growing and transplanting cotton seedlings. 【Background technique】 [0002] For many years, cotton production has been adopting nutrient pot seedling transplanting technology, which has made historic contributions to improving cotton yield and quality and solving the problem of full seedlings. However, nutrient pot seedling transplanting requires a lot of labor, labor intensity is high, and seedbed management is complicated. Affected by rainy and cold weather, cotton seedling raising is already a heavy burden for cotton farmers under the current situation that rural laborers go out to work more. Therefore, there is an urgent need for labor-saving, labor-saving, convenient and fast seedling raising technology. Cotton plug seedling tra...
