Description
Technical field
The present invention relates to field of agricultural production technologies, and in particular to a kind of synchronized by the machine transplanting of rice applies Controlled Release Fertilizer raising early rice
The method of yield.
Background technology
Hunan is the major grain producing area of south China, and rice in Hunan total yield accounts for 87% left side of the whole province's total grain output for many years
The right side, rice have extremely important status in the whole province's grain-production.To ensure increasing production of rice synergy, Hunan is in recent years the machine transplanting of rice
Seedling Technique Popularizing is promoted as the important measures for improving production capacity of rice, Ensuring Food Safety, rice mechanical transplanting area and machine
Slotting rate has the tendency that leaping year after year, is further promoted within 2016 and arrives about 30%, and transplanting rate speedup is very fast, but accelerates to promote and also meet with
Meet many difficulties.Hunan topography and geomorphology is complicated, and field is small and scattered, in addition traditional planting habit influences, Rice Cropping link is complete
Journey Mechanization Level is not also high, becomes the maximum bottleneck of Hunan Province's Rice Production entire mechanization.How to combine Hunan practical prominent
Broken bottleneck promotes rice planting technology, especially changes traditional planting technology, rice planting technology and fertilising are effectively combined, ensured
Rice high yield is efficient, it appears is even more important.
Tradition plantation in apply fertilizer material based on quick-acting fertilizer, this fertilizer due to dissolving soon, fertilizer efficiency is short, is easy to run off,
Fertilizer efficiency is needed and improved to meet growth so to take multiple fertilizer application mode in rice entire breeding time, is manually repeatedly applied
Fertilizer is not only time-consuming, but also be easy to cause fertilising excessively, increases environmental pollution, due to that cannot accomplish scientific and reasonable fertilising,
Cause rice yield that cannot also effectively improve.And Controlled Release Fertilizer can solve the problems, such as rice single fertilization.
Invention content
It is of the existing technology the purpose of the invention is to overcome the problems, such as, a kind of synchronized by the machine transplanting of rice is provided and applies controlled release
The method that fertilizer improves early rice yield, can effectively improve early rice yield, avoid subsequently applying top dressing, save labour.
To achieve the goals above, the present invention provides a kind of side for being synchronized by the machine transplanting of rice and applying Controlled Release Fertilizer and improving early rice yield
Method carries out rice transplanting using machinery and synchronizes disposable accurate fertilizing, and the material that applies fertilizer is Controlled Release Fertilizer and compound of the common fertilizer with synthesis
The ratio of nitrogen is 2 in fertilizer, the Controlled Release Fertilizer and the common fertilizer:8~8:2.
Preferably, the ratio of nitrogen is 2 in the Controlled Release Fertilizer and the common fertilizer:8.
Preferably, nitrogen total amount is 120kg/hm in the compound fertilizer2, phosphorus total amount is 45kg/hm2, potassium total amount is 90kg/
hm2。
Preferably, the Controlled Release Fertilizer is control release urea, and nitrogenous fertilizer is common urea in the common fertilizer.
Preferably, fertilization depth is 5~8cm.
The present invention can effectively improve early rice yield, synchronize single fertilization by the machine transplanting of rice, save labour, Controlled Release Fertilizer
Application can meet needs of the crop in the time of infertility to nutrient, avoid subsequently applying top dressing.
Specific implementation mode
The endpoint of disclosed range and any value are not limited to the accurate range or value herein, these ranges or
Value should be understood as comprising the value close to these ranges or value.For numberical range, between the endpoint value of each range, respectively
It can be combined with each other between the endpoint value of a range and individual point value, and individually between point value and obtain one or more
New numberical range, these numberical ranges should be considered as specific open herein.
The present invention will be described in detail by way of examples below.In following embodiment,
Rice varieties are early rice (two excellent 25) of long-grained nonglutinous rice.
Applied Controlled Release Fertilizer is the control release urea that big ecological limited liability company of Nintaus provides, and peasant habit fertilising is Hunan gold
The common fertilizer that leaf people's expectations Science and Technology Co., Ltd. provides, nitrogenous fertilizer is common urea in common fertilizer, and control release urea is matched with common fertilizer
Synthesize the compound fertilizer of application.
It carries out rice transplanting and synchronizes the machinery that disposable accurate fertilizing uses to be that the 2FH-8 rice transplantings that dragon boat company researches and develops are same
Accurate fertilizing machine is walked, which pushes away fertile structure using the screw compulsory of domestic original creation, using mechanical side deep fertilizing, can determine fertilizer
Amount, fixed point, periodically in the soil of deep placement to rice shoot side, fertilization depth can realize Tree Precise Fertilization in 5~8cm.
Early rice planting density is 12cm × 25cm.Early rice keeps shallow water in one week to pour after rice transplanting, and shallow water pours 2~3
It is secondary, shallow water is kept later and moistens alternate pouring, promotes early rice tiller.Start to shine when reaching the 90% of required effectively fringe seedling number
Field cultivates and strengthens stalk.It is all made of shallow water in early rice boot stage and grouting parameter and moistens alternate pouring, to promote early rice later stage root
It is vigor.
