Abstract
The invention discloses a method of controlling the temperature and the humidity of a greenhouse during a rice seedling raising period. The method for controlling the temperature and the humidity of rice seedlings disclosed by the invention is accord with the growth rule of young seedlings; the color depth of the surface of soil can be improved by adding biochar and a variety of dark raw materials into a heat preserving agent, so that the absorption amount of sunlight is increased; the heat absorption property and the heat preservation property are high; a plurality of stronger water absorbing materials, such as sodium humate, are added into a moisture preserving agent, so that irrigation water can be locked; the moisture preserving agent is remained on leaf surfaces for a long time through high film forming property; good effects in saving water resources and reducing planting cost are achieved; the method of controlling the temperature and the humidity of the rice seedlings disclosed by the invention is suitable for large-scale popularization and application.
Description
Technical field
The present invention relates to planting technology field, the control method of greenhouse temperature humidity during particularly relating to a kind of raising rice seedlings.
Background technology
Along with socioeconomic development, the production situation generation profound change of China paddy rice, promoting with the machine transplanting of rice is that the paddy rice entire mechanization of key technique becomes inexorable trend.China's rice mechanical transplanting Demonstration And Extension is existing for many years, but popularize not yet at present, its reason is many-sided, wherein because transplanting seedling requires high, makes to produce to fail to cultivate and is not only applicable to rice transplanting job requirements but also meets high yield agronomy required standard strengthening seedling and becoming maximum technology barrier.
The quality of seedling quality, heavily plays an important role to the spike number in Rice Growing later stage, grain number and grain, cultivate healthy and strong rice seedling, rice yield is improved further, and the temperature humidity of seedling phase controls particularly important.But make a general survey of various places for many years to the patent research of rice mechanized transplant, find that the patent research in the rich water of seedling planting machinery, seeding quantity, seedtime and Honda is planned strategies for etc. is in the majority, but less for the temperature and humidity control patent research during seedling.
For this reason, current inventor provides a kind of control method of raising rice seedlings greenhouse temperature humidity, be intended to cultivate the rice seedling that quality is high, forming degree is good, positive facilitation is played to the mechanized cultivation of paddy rice and ultimate output.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, the control method of greenhouse temperature humidity during providing a kind of raising rice seedlings.
The present invention is achieved by the following technical solutions:
A control method for greenhouse temperature humidity during raising rice seedlings, comprises following aspect:
(1) during after planting to leaf dew point, temperature of shed controls at 28-30 DEG C, and based on insulation, keeps ground moistening, uses heat preserving agent in soil simultaneously;
(2) will promote the normal growth of root after emerging, temperature of shed controls at 25-28 DEG C, and after planting 3-5 days start the 2-3 hour that ventilates noon, along with the growth of leaf age, and the corresponding prolongation of ventilation time;
(3) control temperature of shed after tidy seedlings output and be no more than 25 DEG C, prevent premature heading, and based on shallow water pouring, promote growth of seedling, training leaf urgees tiller;
(4) rice shoot two leaf is wholeheartedly between transplanting time, temperature controls within 20 DEG C, ventilate round the clock when nocturnal temperature is greater than 12 DEG C, because during this, rice shoot evaporation discharge is large, physiological water requirement amount increases, easy lack of water, therefore will increase water spray number of times and time, spray humectant simultaneously, prevent physiology dehydration from causing dead seedling of wilting.
The method of described raising rice seedlings greenhouse temperature humid control, described heat preserving agent is made up of the raw material of following weight portion: rice straw 95-105, bentonite 23-27, calcium acetate 4-5, iron chloride 0.8-1.2, active carbon 12-15, potassium nitrate 8-10, water are appropriate; Its preparation method is pulverize after tanning by the sun 2-3 days under rice straw being placed in daylight and drop into carbonizing kiln, be warming up to 600-700 DEG C of charing 3-4 hour, obtain biological powdered carbon, mix with active carbon again, after adding 10-12 times of water, mix with calcium acetate, potassium nitrate, iron chloride and be warming up to 70-80 DEG C, stirring 40-60 minute post-drying, then mixing with bentonite and drop into granulation in comminutor; Its using method is that every mu of soil is at shallow soil layer uniform broadcasting 50-60kg.
The method of described raising rice seedlings greenhouse temperature humid control, described humectant is made up of the raw material of following weight portion: CMC 14-16, sodium humate 26-29, Ferric Sodium Edetate 5-7, methane liquid 16-20, ferrous sulfate 1-2, water are appropriate; Its preparation method is the water adding 8-10 times of quality after being mixed with Ferric Sodium Edetate by methane liquid, be warming up to 75-85 DEG C, stir and add ferrous sulfate after 20-25 minute, continue to stir 30-40 minute, sodium humate and CMC is added after solution is down to 50-60 DEG C, again stir 20-30 minute, be down to after room temperature until solution after completing and preserve; Its using method is every mu of soil foliage-spray 25-35kg.
Advantage of the present invention is:
The temperature humidity control method of rice shoot of the present invention meets the growth rhythm of seedling, in heat preserving agent, the interpolation of charcoal and multiple dark raw material can improve upper soll layer color depth, increase the absorptive amount to sunshine, heat absorption heat-proof quality is good, with the addition of the multiple stronger water-absorbing materials such as sodium humate in humectant, irrigation water can be pinned, and be deposited in for a long time on blade by good film forming, have good effect to the saving of water resource and the reduction of planting cost, the control method of rice shoot temp. and humidity of the present invention is suitable for promoting the use of on a large scale.
Embodiment
A control method for greenhouse temperature humidity during raising rice seedlings, comprises following aspect:
(1) during after planting to leaf dew point, temperature of shed controls at 28 DEG C, and based on insulation, keeps ground moistening, uses heat preserving agent in soil simultaneously;
