Embodiment

[0025] 1) Crush the tea cake and oil cake to a particle size ≤ 2mm, and mix them evenly according to the mass ratio of tea cake and oil cake 2:1;

[0026] 2) Turn the plow and ridge about 10 days before transplanting the flue-cured tobacco, and apply the special fertilizer for flue-cured tobacco as a base fertilizer at one time during the ridge formation, with a pure nitrogen content of about 75kg per hectare, and the specific amount will be adjusted according to the local soil fertility status;

[0027] 3) Cover with plastic film a few days before transplanting, preferably after rain to ensure moisture content;

[0028] 4) The transplanting density is 1.5×10 4 Plants / hectare or so, adjust as appropriate according to local ecological conditions and transplanted varieties, and use small transplanting shovel to make nests on the plastic film according to the predetermined plant spacing and row spacing, and ensure the nest depth is 30cm;

[0029] 5) Use a small spoon to pour 100g of repel...

Abstract

The invention discloses a flue-cured tobacco transplanting method for expelling and killing blackcutworm. The method comprises the following steps: adding powder prepared by mixing tea and oil cakes in a certain proportion in nest bottom under the background of a plastic membrane mulching tobacco planting technology, expelling and killing the blackcutworm in and around the tobacco nest; directly killing the blackcutworm after transplantation or expelling and killing the blackcutworm after climbing on the mulching film. The concrete technical steps are as follows: (1) respectively grinding the tea and the oil cakes and mixing; (2) ridging before flue-cured tobacco transplantation, and applying base fertilizer in strips once; (3) covering film before plantation and keeping soil moisture content; (4) nesting on the mulching film in fixed point when transplanting; (5) inpouring the destroying and expelling agent into the tobacco nest, and covering a small amount of soil for mixing evenly; and (6) planting tobacco seedling to finish transplantation. The method of the invention has the advantages of environmental protection, economy, wide raw material source, good disinfestation effect, simple operation and strong practicability; the invention turns waste into wealth, is easy to popularize, and is a flue-cured tobacco transplantation mode with good effect, low cost and simple operation.

Description

Technical field [0001] The invention relates to flue-cured tobacco cultivation technology, and also to insecticides, especially to the technology for driving and killing cutworms in field transplanting of flue-cured tobacco. Background technique: [0002] Cutworms belong to the Lepidoptera Noctuidae family (Noctuidae), also known as soil silkworms, and are one of the main pests in tobacco areas. Among them, the cutworm [Agrotisypsilon (Rottemberg]) is more harmful to flue-cured tobacco production in southwest tobacco areas. Its small larvae damage young shoots, tender stems, and young leaves. After 3 instars, they can bite the roots and necks of seedlings and cause dead seedlings. Sometimes the larvae return Drag the broken seedlings into the holes to make the seedlings stand up with their roots cut off. Especially in the case of flue-cured tobacco within half a month after transplanting, the seedlings must be supplemented frequently, which is laborious and time-consuming. At pre...
