Abstract
A kind of method at alkalescence soil maize planting, the method utilizes soil conditioner to make the pH value of acid ground plow layer remain between 7.0 ~ 8.5, soil is made to become alkalescence, then maize planting in this subalkaline soil, its method comprises: sampling, survey soil are filled a prescription, soak seed dressing, sowed and field management; This method can eliminate the pollution of heavy metal in soil to corn, and the yield and quality of raising corn, is adapted at China's acid ground growing area and heavy metal pollution district applies.
Description
Technical field
The present invention relates to soil melioration and crop cultivation methods, particularly a kind of method at alkalescence soil plantation corn crop.
Background technology
At present, generally believe that corn only should grow at the acid ground of PH6.0 ~ 7.0, but along with industrialized process, the SO discharged in air
3, SO
2, NO
2, the goods and materials such as NO are increasing, thus form acid rain soil is hardened day by day, meanwhile, strong sulfate radical and nitrate anion etc. have activated again heavy metal ion a large amount of in soil, typical in lead, cadmium, chromium, mercury, arsenic.Along with the raising of soil acidity, the active part progressively passivation of the element needed for crop, form the goods and materials as calcium phosphate, calcium silicates etc. not easily absorb, cause the availability of the fertilizer in being manured into soil more and more lower, thus occurred that planting cost is more and more higher, output is more and more lower, particularly gained agricultural product heavy metals exceeding standard, causes serious impact to the health of eater.
Summary of the invention
Only the above-mentioned defect brought should be grown by the acid ground in PH6.0 ~ 7.0 for overcoming existing corn, the object of this invention is to provide a kind of method at alkalescence soil maize planting, in order to adapt to current ecotope, silicon in activating soil and phosphorus, the heavy metals such as precipitation passivation lead, cadmium, mercury, chromium, arsenic, improve the basicity of agricultural product, that guarantees on people's the tip of the tongue is healthy and safe.
For solving its technical problem, the technical solution used in the present invention is: the method utilizes soil conditioner to make the pH value of plough horizon remain between 7.0 ~ 8.5, make soil become alkalescence, then maize planting in this subalkaline soil, its implantation methods comprises the steps:
Step one, sampling: first will prepare the standard sample of farmland by agricultural sector of maize planting, its depth selection must not be less than 20cm;
Step 2, survey soil formula: the pH value of got soil sample is adjusted to about 9, record the kind consumption of soil conditioner used and the time needed for PH falling, the character of the sample areas soil of combining step one, by the community experiment of to three year, gets the Changing Pattern of P in soil H clear;
Step 3, leaching seed dressing: be watered with basic soil conditioner, make its pH value control between 7.0 ~ 8.0 seed soaking, is then mixed into suitable sand or fertilizer and corn seed dressing wherein;
Step 4, sowing: adjusted between 7.5 ~ 8.5 by the PH of corn field soil, be then sown in soil by soaking the corn seed mixed;
Step 5, management: when maize seedling grows to two leaf one cores, with soil conditioner, the pH value of corn field soil is adjusted to 7.0 ~ 8.0, within the vegetative period of the seedlings of cereal crops, take every 5-10 days and carry out primary sample detection soil sample, the change of record pH value, particularly for heavy metal pollution area, if find that the pH value of soil falls less than 7 after rise at corn Filling stage, benefit is also needed to execute soil conditioner, guarantee its PH be greater than 7 and heavy metal ion be in passivation sequestering properties, thus ensure heavy metal ion do not absorbed by corn seed.When pH value is greater than 8.5, if deep ploughing can be taked once in vacant lot, pH value once all can be made to fall after rise if filling can be soaked when having crop;
Wherein, described soil conditioner is the existing product that market is buied, and preferably the applying date is on June 24th, 2014, number of patent application is the soil conditioner of 201410285528.8.
Compared with prior art, the present invention has following substantive distinguishing features and progress significantly: because of the method for maize planting crop of the present invention, utilize soil conditioner to make the pH value of plough horizon remain between 7.0 ~ 8.5, soil is made to become alkalescence, then maize planting in this subalkaline soil, its method comprises: sampling, survey soil are filled a prescription, soak seed dressing, sowed and field management; This method can eliminate the pollution of heavy metal in soil to corn, improve the yield and quality of corn, fundamentally eliminate the harm that soil acidification and heavy metal pollution bring, for agriculture good quality and high output low consumption is laid a good foundation, adapt to widely apply at China's acid ground growing area and heavy metal pollution district.
Embodiment
Below by embodiment, the present invention is further described:
Embodiment one, alkalescence soil plantation corn crop method, comprise the steps:
Step one: in farmland sampling, its degree of depth is 20cm;
Step 2: survey soil formula, community corn experiment field arranges the experiment of a production cycle by pH value 8.5, determine to soak dress seed, sow, whole growth of earing with the pH value of the change of control group;
Step 3, leaching seed dressing: be watered with the soil conditioner that market is chosen and make it pH=9.0 sterilization, then in water, be mixed into sand or fertilizer, make its PH between 7.0 ~ 7.5, corn seed is stirred with it;
Step 4, sowing: before sowing, with soil conditioner, the P in soil H of corn field is adjusted to 7.0 ~ 7.5, then sow according to a conventional method, when rice shoot reaches two leaf one cores, the pH value of corn field soil is adjusted to 7.5 ~ 8.5, make its maize seedling all be in weakly alkaline environment growth;
Step 5, within the seedlings of cereal crops full vegetative period, take 5-10 days and carry out primary sample detection soil sample, the change of record pH value, particularly for heavy metal pollution area, at crop Filling stage, if find, the pH value of soil falls less than 7 after rise, need mend and execute soil conditioner, guarantee its pH value be greater than 7 and heavy metal ion be in passivation sequestering properties, thus ensure heavy metal ion do not absorbed by crop seed; Wherein, described soil conditioner is the applying date that market is buied is on June 24th, 2014, number of patent application is the soil conditioner of 201410285528.8, or the existing product that function is similar to it.
Sufficiently illustrate improvement acid ground by above embodiment to make it to become alkalescence and not only activated phosphorus and silicon, but also the multiple harmful heavy metal of passivation chelating, particularly supplement a large amount of moderate-elements, for basis has been tamped in the good quality and high output of corn, low consumption.
