Abstract

The invention provides a mud seedling raising method of transplanted seedlings for a rice machine. The mud seedling raising method comprises arranging a rectangular seedling bed with side walls with a certain height in the periphery as a seedling raising carrier; placing the rectangular seedling bed in a seedling raising field which is well prepared; adding rice paddy mud into the rectangular seedling bed, wherein the rice paddy mud needs to be solidly sunk with a standard that seeds fall into the mud without sinking during sowing; laying the mud flat in the rectangular seedling bed as subsoil with the thickness of 1.5 to 2.3 cm; and sowing the rice seeds and covering substrates after the sowing, wherein the thickness of the substrates can completely cover the seeds and not more than 5 mm preferably. The mud seedling raising method of the transplanted seedlings for the rice machine has the advantages of being capable of improving the seedling rate of the seedling transplanting of the rice machine, improving the uniformity of seedling emergence, promoting the growth of seedling root systems, improving the intertwining fastness of the seedlings, improving the machine transplanting effect and being simple and practical to operate and low in cost.

Description

The rice mechanical transplanting mud method of raising seedling of rice shoot

Technical field

The present invention relates to the paddy rice planting technology, be specifically related to the mud method of raising seedling that rice mechanical transplanting is used rice shoot.

Background technology

The rice mechanization rice transplanting is adopted standard seedling dish usually with rice shoot, the matrix that in the seedling dish, adds rice field mud soil or nonirrigated farmland soil or mixed in proportion by suitable seedling growth material, sowing then, allow seed sprouting, root growth dish knot, breed seeding root and form the blanket appearance seedling of sheet, rice mechanical transplanting requires rice shoot must become blanket.Use the soil workload that fetches earth in nonirrigated farmland big in the machine transplanting of rice seedling, and can destroy the soil structure of dry land.And the seedling raising ground substance cost that uses suitable seedling growth material to mix in proportion is higher.Adopt rice field mud soil seedling, can gather materials on the spot saving of labor's abridged edition, but because traditional rice field mud indigenous method adopts rice field mud as the machine transplanting of rice seedling soil of trying to get to the heart of a matter, sowing after planting covers seed with mud then, because the gas permeability of rice field mud soil is relatively poor, make planting percent lower, outside then seed was exposed to without mud covering seed, the upper surface dehydrating speed was fast, emergence rate also is affected, therefore pure rice field mud seedling, emerge poorly, and the regularity of emerging is poor, and makes rice shoot become blanket poor.Hybrid rice machine transplanting of rice seedling is low because of seeding quantity, and this phenomenon is more serious, machine transplanting of rice weak effect.

Summary of the invention

Technical problem to be solved by this invention provides rice mechanical transplanting with the mud method of raising seedling of rice shoot, with realize low cost and emerge neat, become blanket good, reach the strengthening seedling of rice machine standard.For this reason, the present invention is by the following technical solutions:

The rice mechanical transplanting mud method of raising seedling of rice shoot, it is characterized in that it utilizes periphery to be provided with the rectangle seedling dish of the limit wall with certain altitude as the carrier of seedling, put the seedling field for preparing, rice field mud is joined in the seedling dish, mud need be through heavy real, with when sowing seed drop to that not sink on the mud be standard, mud is tiled in the seedling dish as subsoil, thickness is at 1.5-2.3cm; Sow paddy seeds then, after planting cover matrix; Stromal thickness is to cover seed fully for well, and thickness is no more than 5mm.

Described matrix is that main component is other agricultural waste material except husk, earth, the peat of crushed material, the pulverizing of the broken required mineral matter element material of husk, paddy rice, the mixture of PH conditioning agent, through microbial fermentation, pulverize and sieve and handle the mixture be made into, this matrix has the characteristics of good water absorption, good permeability.

1), the mud appropriateness is heavy real in the seedling dish, prevents from sinking behind the planting seed, causes the seed hypoxia death the present invention has following beneficial effect:.2), cover the covering matrix of certain thickness preparation behind the planting seed, can heat and moisture preserving, reduce the influence of climatic variation, be more suitable for seed growth, improve planting percent.3), matrix covers seed, can improve seedling growth environment air capacity of soils, promotes root growth, improves root system dish knot ability, forms blanket appearance seedling easily.4), rice field mud is as the seedling subsoil, it is convenient to obtain, cost is low, the higher rice shoot that brings out that makes of the cohesiveness of rice field mud is easier to into blanket.

To sum up, rice mechanical transplanting provided by the present invention can improve rice mechanical transplanting seed planting percent with the mud method of raising seedling of rice shoot, improves the seed sprouting regularity, promotes the rice shoot root growth, improves rice shoot dish knot stability, improves machine transplanting of rice effect.And this method is operated simple and easy practicality, cost is low.

Embodiment

With reference to accompanying drawing.The present invention utilizes periphery to be provided with to have the rectangle disk body 1 of limit wall of certain altitude as the carrier of seedling, neatly put the seedling field for preparing, and rice field mud 2 put in the disk body 1, mud 2 needs through heavy real, sow paddy seeds 3 then, paddy seeds for well, after planting covers the matrix 4 for preparing through presoaking and germinating.Mainly may further comprise the steps:

1, the farming of pouring water by the field, smooth, processes such as trench digging are made the smooth seedling field 5 that is divided into stick that is fit to the rice seedling growth, the rectangle seedling dish 1 that periphery is provided with the limit wall with certain altitude neatly is placed on the rice seedling bed 5 by a definite form, and guarantee that 1 end of seedling dish contacts fully with 5 surfaces, rice seedling bed, and prepare rice field mud 2 on the spot in the seedling field, in mud 2 tiling seedling dishes, mud 2 thickness are greater than 1.5cm, generally needn't surpass 2.3cm, mud 2 upper surfaces leave a segment distance apart from seedling web wall top in the seedling dish, space as sowing seed 3 and covering matrix 4, mud 2 as subsoil needs heavy real a period of time, exclusive segment moisture content, generally decide according to water content of slurry, during with sowing, seed rice drops on the mud not sink to getting final product.

2, after mud 2 sinks in fact in the seedling disk body 1, broadcast seed 3 by machinery or the artificial mud 2 of mode in seedling disk body 1, seeding quantity is decided according to the actual requirements.After planting cover ready matrix 4 at seed 3, the even spreading of matrix, thickness is no more than 5mm to cover seed fully for well.Cover transparent insulation film or nonwoven then as required, heat and moisture preserving is emerged and seedling growth provides condition for seed 3, cultivates rice shoot.When pouring water by the seedling dish during matrix 4 lacks of water above the seedling dish, allow the soil suction in the seedling dish keep the skin wet.Breed until rice shoot.

Described matrix is the material of ventilative suction, and being rich in nutrition.It can adopt following method to make in advance: it takes main component is other agricultural waste material except husk, earth, the peat of crushed material, the pulverizing of the broken required mineral matter element material of husk, paddy rice, the mixture of PH conditioning agent, through microbial fermentation, pulverize and sieve and handle the mixture be made into, this matrix has the characteristics of good water absorption, good permeability.
