To achieve these objects and other advantages in accordance with the present invention, there is provided a method for growing seedlings of temple acer mono seeds, comprising the steps of:
soaking seeds in a disinfectant for 8-15 min, washing with sterile water, and then placing in a cool and ventilated place for airing;
step two, digging a sand storage pit, uniformly mixing the aired seeds with wet river sand with the water content of 60-80% according to the volume ratio of 1: 3-5, filling the mixture into the sand storage pit, laying a layer of thin wet river sand on the top, covering a woven bag, turning the mixture once every 7-14 days, and spraying a proper amount of sterile water after each turning until 30-50% of the seeds have bud spots;
step three, pouring a proper amount of 20-25 wt% carbendazim wettable powder 500-800 times of liquid medicine on a seedbed, and then sowing seeds on the seedbed, wherein the seedbed comprises: sequentially paving a pine needle-clover mixture layer, a matrix soil layer and a perlite layer from top to bottom;
the preparation method of the pine needle-clover mixture layer comprises the following steps:
soaking pine needles in soap water for 1-2 h, then washing, drying and cutting into 1-2 cm to obtain pine needle sections;
pulverizing herba Trifolii Pratentis, soaking in clear water, filtering, and oven drying to obtain herba Trifolii Pratentis powder;
and stirring and mixing the pine needle segments, the clover powder and 2-5 wt% of hydroxypropyl methylcellulose uniformly.
Preferably, the matrix soil layer in the third step comprises the following raw materials in parts by weight: 45-60 parts of brown soil, 30-40 parts of pine needles, 3-7 parts of compound microorganisms, 10-15 parts of sawmilling residues and 2-6 parts of EM (effective microorganism) powder.
Preferably, the preparation method of the matrix soil layer in the third step comprises the following steps:
adding a proper amount of water into the brown soil, and stirring until the soil is in a mud state to obtain brown soil mud;
soaking pine needles in soap water for 1-2 hours, cleaning, drying and crushing to obtain pine needle powder;
fermenting the sawn wood residues by using compound microorganisms to obtain a fermentation liquid and fermentation residues;
fully and uniformly stirring the brown soil mud, the pine needle powder, the fermentation liquor, the fermentation residues and the EM bacteria powder, adjusting the pH to 5.5-6.6 by using a saturated potassium carbonate solution and a saturated phosphoric acid solution, airing, and then covering a degradable mulching film on the surface of the soil for 2-3 days to obtain the matrix soil layer.
Preferably, the disinfectant in the first step is a solution prepared by mixing 10-12 wt% of Bordeaux mixture and 20-25 wt% of carbendazim according to the volume ratio of 1: 1.
Preferably, the method further comprises the step two of disinfecting the river sand, and the specific method comprises the following steps: and (3) spraying 0.2-0.4 wt% of potassium permanganate solution, wrapping the plastic cloth, and airing the plastic cloth in the sun for 2-3 days.
Preferably, the weight parts of the compound microorganism in the third step are 20-30 parts of propionic acid bacteria and 50-60 parts of lactobacillus acidophilus.
Preferably, the seedbed in the third step has a ridge length of 1.2-1.5 m, a ridge width of 0.8-1 m, a ridge height of 0.15-0.25 m and a step width of 0.4-0.6 m.
Preferably, the sowing mode of the step three is drill sowing, and the parameters of the drill sowing are as follows: the sowing width is 8-10 cm, the row spacing is 5-8 cm, and the depth is 4-6 cm.
The invention at least comprises the following beneficial effects:
firstly, the pine needle-clover mixture layer is adopted to cover the matrix soil layer, so that the water evaporation in the matrix soil layer is reduced, the temperature of the matrix soil layer is increased, the soil moisture preservation and moisturizing effects are achieved on the matrix soil layer, the emergence rate of the Temple chiffon seeds is improved, meanwhile, the pine needle and the clover are decomposed by microorganisms to form humus, and the humus provides the seedlings with nutrient components consisting of nutrient elements such as nitrogen, calcium, phosphorus and the like, so that the growth of the seedlings is promoted.
Secondly, at present, less research on artificial breeding of temple acer mono is carried out, and the emergence rate of seeds is low.
Thirdly, fermenting the sawmilling residues by adopting propionic acid bacteria and lactobacillus acidophilus to generate a fermentation liquid and fermentation residues, wherein the fermentation liquid contains abundant lactic acid and acetic acid, and promotes calcium, phosphorus and iron in soil and the fermentation residues to be converted into quick-acting calcium, quick-acting phosphorus and quick-acting iron which are easy to absorb by seedlings, and the fermentation residues are comprehensive in nutrition and cannot cause the plants to have rich nitrogen and lack phosphorus and potassium, so that the nutrient substrate of a substrate soil layer is enhanced; meanwhile, EM bacterial powder is matched, the diversity of bacterial colonies in a matrix soil layer is increased, the conversion and circulation of organic matters and nutrients in the matrix soil layer are promoted, and the balance of the bacterial colonies and the nutrient medium in the matrix soil layer is guaranteed.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention.
