Abstract

The invention belongs to the field of soil improvement, and particularly relates to a special green cultivation soil for planting blueberry and a preparation method thereof, the special green cultivation soil comprises the following compositions: dead moss, pine needle, common mineral soil, sulfur powder and a mycorrhizal fungi spore turbid liquid (QM15), and the pine needle and the moss are simple renewable resources, and are wide in distribution area, low in price, and readily available. In a preparing process, the sulfur powder is added and then water is added to cover the sulfur powder, and the bactericidal effect of the sulfur powder is used to disinfect the mixed cultivation soil, so that an individual disinfection process is omitted, the cost is further reduced, the preparation process of the cultivation soil is simplified, and the preparation method is conducive to fast preparation of the cultivation soil; addition of mycorrhizal fungi after disinfection is conducive to field planting of the mycorrhizal fungi and establishing of beneficial dominant population and the success rate of mycorrhizal inoculation of the blueberry can be improved.

Description

A kind of for cultivating special-purpose non-toxic compost of blueberry and preparation method thereof

Technical field

The invention belongs to soil improvement field, a kind of special cultivation soil of cultivating blueberry of specific design and preparation method thereof.

Background technology

Blueberry (blueberry) formal name used at school (Vaccimium spp), belong to Ericaceae genus vaccinium (or Vacciniodeae) plant, claim again blue berry, the gorgeous unique flavor of its fruit colour, be rich in the high anthocyan material of abundant VITAMIN, mineral substance and multiple anti-oxidant activity, having very high health protection effect, is a kind of novel functional fruit.China's blueberry cultivation is started late, and from nineteen eighty-three, starts to introduce and cultivate research work, and development recent years rapidly, has begun to take shape industrialization cultivation.As the emerging fruit tree of a kind of third generation, the cultivation management of blueberry is compared obviously different from other fruit trees.Blueberry root hair is few, shallow root, and the histogram of root mass, in thin solum, is applicable to growing in organic content and reaches more than 3% soil, requires soil pH 4.5 ~ 5.5 simultaneously.Because blueberry cultivation condition is harsher, therefore soil improvement all will be carried out in most of areas.

Along with the surging of blueberry plantation upsurge and the lifting to blueberry plantation special-purpose soil demand, prepare completely, for different blueberry kinds, plant required compost and just seem particularly important.We are when carrying out blueberry plantation practice, first the problem running into be exactly to cultivating required soil, carry out fast, the simple and not high improvement of cost, the blueberry that makes plantation is in growing way or at percentage of fertile fruit or in mouthfeel, all occupy certain advantage.Because grow required Soil Habitat and most of planting site soil and common farm crop of blueberry has very large difference, therefore also just more difficult aspect soil improvement.For plantation blueberry, past all adopts turfy soil, ripe pine needle to soil improvement, and vermiculite, and the additional multiple mineral manure of the artificial soils such as perlite is mixed, but wherein turfy soil used is only distributed in a small amount of areas such as northeast, and storage is limited, though can also utilize in present stage, belong to Nonrenewable resources, and the digest process of pine needle is very long, also be unfavorable for quick improvement, and in soil, mix vermiculite, the artificialities such as perlite also can bring considerable influence to edatope.And the mixing of mineral manure also can make blueberry failure in carrying out green food authentication.A lot of bibliographical informations are crossed the symbiotic relationship of liver moss, tamarack and wild blueberry, but have no report for the required special soil of manual inseminating's blueberry aspect.

Summary of the invention

In view of the problem that prior art exists, object of the present invention will provide a kind of for cultivating special-purpose non-toxic compost of blueberry and preparation method thereof

For achieving the above object, the technical solution adopted in the present invention is a kind of for planting the special-purpose non-toxic compost of blueberry, its moiety comprises: dead liver moss, fallen leaves pine needle, common mineral soil, SULPHUR POWDER and VA Mycorrhizal Fungi spore suspension liquid (QM15), the weight percent of described each material is: dead liver moss 25% ~ 35%, fallen leaves pine needle 45% ~ 55%, mineral soil 15% ~ 25%, SULPHUR POWDER 1kg/m ³, VA Mycorrhizal Fungi suspension liquid 1L/m ³.

The VA Mycorrhizal Fungi of described VA Mycorrhizal Fungi suspension liquid for extracting from blueberry platymiscium, configuration suspension liquid concentration is 5000/ml.

Described for planting the preparation method of the special-purpose non-toxic compost of blueberry, its process is as follows:

The first step: checkmating, liver moss is mixed in proportion with fallen leaves pine needle, the air-dry rear segment that utilizes pulverizer to be ground into 5 ~ 8cm;

Second step: mineral soil is admixed in the mixture of the first step, and added SULPHUR POWDER;

The 3rd step: add the agricultural water of 0.6 cubic metre in every cubic metre of mixed cultivating soil, cover and preserve 2 weeks;

The 4th step: add VA Mycorrhizal Fungi suspension liquid after opening coverture.

The invention has the advantages that: fallen leaves pine needle and liver moss are all simple renewable resources, and Distribution Area is extensive, low price, easily obtains.In preparation process, adding and adding that water covers after sulphur powder is to utilize the germicidal action of sulphur powder to carry out disinfection to mixed cultivating soil, therefore omitted independent sterilizing process, make the further reduction of cost, and also simplified compost preparation process, be conducive to the quick preparation of compost.And after sterilization, carry out again the interpolation of VA Mycorrhizal Fungi, be also conducive to the field planting of VA Mycorrhizal Fungi and the foundation of useful dominant population, increase the success ratio of blueberry mycorhiza inoculation.

After soil configures one month, can record soil ph value 4.5 left and right, specific conductivity 1380ms/cm left and right, soil microbial biomass 800mg/kg left and right, and at plantation blueberry, after 1 year, measure Mycorrhizal Infection Incidence and can reach more than 60%, therefore can judge that this compost meets blueberry growth requirement completely.

Embodiment

A kind of for planting the special-purpose non-toxic compost of blueberry, its moiety comprises: dead liver moss, fallen leaves pine needle, common mineral soil, SULPHUR POWDER and VA Mycorrhizal Fungi spore suspension liquid (QM15), the weight percent of described each material is: dead liver moss 30%, fallen leaves pine needle 50%, mineral soil 20%, SULPHUR POWDER 1kg/m ³, VA Mycorrhizal Fungi suspension liquid 1L/m ³.

The first step: the liver moss of checkmating is mixed in proportion with fallen leaves pine needle, the air-dry rear segment that utilizes pulverizer to be ground into 5cm left and right;

As two kinds of compost contrasts take turfy soil and vermiculite be main compost respectively within 2 years, generating northern highly cultivate from blueberry of long-term and 5 years raw rich fruit phases, plant 1 year after controlling its other environmental factors, obtain following increment and yield comparison as table 1

The different compost types of table 1 are to blueberry increment and yield effect contrast

Note 1: in table, numeral is mean+SD, different letter representations significant difference in ducan multiple comparisons after numeral

As can be seen from the table, under this patent compost, gained blueberry in vegetative period height increment of seedlings is significantly higher than other two kinds of composts, and in rich fruit phase blueberry output, is also significantly higher than other kind composts, and it is with the obvious advantage as seen.
