Description
Technical Field
The invention relates to the technical field of forestry disease and pest control, in particular to a pine wood nematode tracery economic tree planting method.
Background
At present, the pine wood nematode disease seriously threatens abundant pine forest resources in China, not only causes great loss to national economy, but also destroys natural landscape and ecological environment. Therefore, how to reform forest stands on the pine line worm tracks, recover damaged pine forest as soon as possible and improve the ecological function of the damaged pine forest is the current urgent work and has very important significance.
In view of the above, the present invention is particularly proposed.
Disclosure of Invention
The invention aims to provide a pine wood nematode tracery economic tree species replanting method which can be used for popularization and application of forest stand reconstruction of pine wood nematode tracery, and can recover damaged pine forests and improve ecological functions of the damaged pine forests as soon as possible.
In order to solve the technical problem, the invention provides a pine wood nematode tracery economic tree planting method, which comprises the following steps:
(1) cleaning the diseased plant residues and setting an isolation belt;
(2) selecting the economic tree seedlings;
(3) replanting the nursery stock at a position 50-80 cm away from the diseased plant residue;
(4) and irrigating, fertilizing, pest control and cold-proof treatment are carried out on the nursery stock.
Preferably, the step (1) comprises applying the nematicide to soil of the diseased plant residue after cleaning the diseased plant residue.
Preferably, the selected economic tree species are container seedlings, the diameter at breast height of the seedlings is 3-6 cm, and the height of the seedlings is 1-1.2 m.
Preferably, the step (3) of replanting the nursery stock specifically comprises the following steps: firstly, digging supplementary planting holes with the specification of 50 multiplied by 50cm, and keeping the spacing between the supplementary planting holes to be 3 multiplied by 3 m; applying the organic fertilizer to the bottom of the hole, wherein the dosage is 500 g/hole; then the container seedlings are put into the replanting holes, covered with soil and treaded tight for 2-3 times, and covered with a layer of loose soil.
Preferably, the nursery stock is irrigated with rooting water added with auxin immediately after the replanting, and irrigated once a day within 10 days later to keep the soil moist.
Preferably, the fertilizing step comprises: and after 2 months of replanting, applying 0.2-0.3 g of nutrient fertilizer to each seedling, and applying the nutrient fertilizer within 5 years after replanting, wherein the application amount of the nutrient fertilizer is 1.5 times of that in the previous year.
Preferably, the pest control comprises 1-time pest killing by using a pesticide and sterilizing agent every month, wherein the pesticide and sterilizing agent is prepared from the following raw materials in parts by weight: 10-30 parts of coptis chinensis extract, 15-20 parts of wormwood extract, 10-20 parts of radix sophorae flavescentis extract, 15-20 parts of pepper extract, 10-15 parts of garlic extract, 20-25 parts of pyrethrum extract and 50-60 parts of water.
Preferably, the cold-proof treatment comprises coating the whole nursery stock with an anti-freezing whitening agent or wrapping the nursery stock with a plastic film tape to wrap the whole nursery stock.
Preferably, the nematicide is prepared from the following raw materials in percentage by weight: 0.1 to 0.3 percent of acetamido abamectin, 3 to 5 percent of brevibacillus laterosporus, 15 to 20 percent of allyl isothiocyanate, 15 to 20 percent of ricinine and the balance of water.
Preferably, the economic tree species are selected from any 3-4 species of liquidambar formosana, pterocarpus santalinus, zelkova, pterocarpus mongolicus, maple, albizzia julibrissin, fago, come tree, acer truncatum, box tree, arborvitae, juniper pennyensis, fagopyridae and oak species, and the same tree species are planted in a centralized way.
Compared with the prior art, the invention has the beneficial effects that:
the pine wood nematode tracery economic tree planting method can be used for popularizing and applying forest stand reconstruction on the pine wood nematode tracery, and can recover damaged pine forests and improve the ecological function of the damaged pine forests as soon as possible.
