Abstract
The present invention provides a kind of seedling raising device of the above the average age for marriage rice shoot of suitable machine transplanting of rice and its applications, belong to technical field of agricultural cultivation.Seedling raising device of the present invention includes seedling-cultivation plate, matrix and seedling paper, from top to bottom successively includes: the first seedling paper, hypothallus, the first nutrient-raising rice seedlings paper and the second nutrient-raising rice seedlings paper in the seedling-cultivation plate.Using seedling raising device of the invention, at the length of time rice seedlings grow 20 days, rice shoot height is lower than control, rice shoot stem foot is wide, leaf area, chlorophyll content, overground part and weight of root system dramatically increase, root/shoot ratio and the disk knot power of root system, root activity also greatly improve, and show that seedling raising device of the invention is remarkably improved seedling quality.In addition, seedling quality, which is also significantly greater than, to be compareed when the length of time rice seedlings grow was by 30 days, rice shoot highly significant is still suitable for the machine transplanting of rice lower than control.It can be seen that method of raising seedling of the invention is able to extend the suitable cultivation phase of rice shoot.Meanwhile method of raising seedling of the invention also reduces substrates quantity, can be peasant's save the cost, improve effect.
Description
Technical field
The invention belongs to technical field of agricultural cultivation, and in particular to a kind of above the average age for marriage raising seedling device of the suitable machine transplanting of rice and its
Using.
Background technique
Under the premise of Current mechanical rice transplanting, cultivates and the rice shoot of the machine transplanting of rice is suitble to be also needed for situation, and transplanting is to seedling
The seedling length of time rice seedlings grow requires stringenter.If the machine-transplanted rice length of time rice seedlings grow is too long, it will appear height of seedling increase, yellow leaf increases, and rooting ability decline shows
As not only bad for the raising of machine transplanting of rice quality, and rice shoot turns green work slowly, influences tiller, and crop field tiller is caused to start to walk
In evening, effective tillering section is few, and influences the formation of suitable spike number needed for high yield in turn, reduces rice yield.Test display, matrix
The suitable rice transplanting age of seedling, cultivation was proper, and per mu yield can be super very heavy within the scope of 15~20 days, but the length of time rice seedlings grow every extension one day, under yield
Drop 1.4%.
In recent years, in seedling, due to taking native difficult, Nutrition Soil to puddle becoming increasingly conspicuous for the problems such as uneven, lead to rice shoot
Quality is irregular, and burn seedlings phenomenon is more universal, has seriously affected the production of rice.So the mode of Nutrition Soil seedling just by
Gradually substituted by matrix seedling.Although matrix seedling has compared with Nutrition Soil seedling, technically simple, low in cost, success rate is high, suitable
The advantages that closing the machine transplanting of rice, but matrix seedling also has its shortcoming.Firstly, late effect property of the matrix seedling relative to its fertilizer efficiency of Nutrition Soil
Short, rice shoot is easy de- fertilizer after 1 leaf, 1 heart and turns yellow；Secondly, the physical property of matrix determines its poor water retention property, rice shoot is increased
Water management difficulty；Third, if matrix is decomposed, fermentation is insufficient, stirring is uneven, easily causes burn seedlings dead seedling etc. existing
As, so alignment seedling, packing influence greatly.
During current Rice Production, stubble maturation is postponed before often encountering, and rainy weather postpones harvest time, mechanical
Situations such as device fails, causes that transplanting cannot be implemented in planned time, cannot transplant so as to cause of the right age rice shoot.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of above the average age for marriage raising seedling device of suitable machine transplanting of rice and its educating greatly
