Flue-cured tobacco shallow nest cover small hole deep planting method and integrated tool for digging and punching

Abstract

The invention discloses a flue-cured tobacco deep-planting method adopting small holes formed in shallow pits and a pit digging and hole punching integrated tool. The method comprises steps as follows: (1) soil preparation, ditching, row fertilization with base fertilizer and ridging are performed; (2) the shallow pits with diameters ranging from 20 cm to 25 cm and depths ranging from 8 cm to 10 cm are dug in ridge bodies by the aid of the pit digging and hole punching integrated tool firstly, and then the small round holes with diameters ranging from 5 cm to 6 cm are punched in bottoms of the shallow pits; (3) tobacco seedlings are vertically placed into the small holes with roots facing downwards, and growing points of the tobacco seedlings are exposed out of ports by 1-2 cm; (4) rooting water in which hole applied fertilizer and insecticide are dissolved is poured to soil around the ports; (5) a mulching film covers the ridge bodies, the tobacco seedlings are exposed, and film openings are sealed; (6) after 15-20 days after transplantation, side topdressing is performed at bottoms of the shallow pits, the shallow pits are filled with soil, and then conventional management is performed. The method has the advantages that the pit digging and hole punching strength is low, damage to the ridge bodies is little, the fertilizer does not lose easily, deep planting of the tobacco seedlings is realized, the survival rate of the tobacco seedlings is increased, topdressing is facilitated, impoundment for drought resistance is facilitated, labor for transplantation and topdressing links is reduced, and the like.

Description

technical field [0001] The invention relates to a method for deep planting of flue-cured tobacco with small holes in shallow nests and an integrated tool for digging and punching holes, and belongs to the technical field of flue-cured tobacco cultivation. Background technique [0002] Flue-cured tobacco planting mainly adopts the method of growing seedlings first and then transplanting, and transplanting tobacco seedlings is an important link in tobacco planting. The traditional way of transplanting flue-cured tobacco is to make a ridge first, then make a large nest on the ridge, put the tobacco seedlings in, cover with soil, compact, and water the roots. Nesting is generally done with a hoe, which requires multiple times of digging out the soil, which is time-consuming and labor-intensive; at the same time, the ridge body is greatly damaged, and the base fertilizer applied in strips is taken out of the ridge body, causing fertilizer loss; or the nesting is too shallow to ac...

Problems solved by technology

Nesting is generally done with a hoe, which requires multiple times of digging out the soil, which is time-consuming and labor-intensive; at the same time, the ridge body is greatly damaged, and the base fertilizer applied in strips is taken out of the ridge body, causing fertilizer loss; or the nesting is too shallow to achieve deep planting of tobacco seedlings

Chinese Patent No. ZL201110203197.5 "Transplanting Method of Flue-cured Tobacco Mulching Well Cellar Seedlings" and No. ZL201310373496.2 "Circular Hole Transplanting Method for Open Field Cultivation of Flue-cured Tobacco" respectively solved the unfavorable climate drought during the transplanting period in some flue-cured tobacco production areas. After the seedlings are transplanted, the seedling period is longer, and the damage to the ridge body caused by the hole in the transplanted pit, the compact soil in the hole is not conducive to the growth of the root system of the tobacco seedlings

However, the aforementioned transplanting method adopts deep pit holes or small round holes on the ridge. At present, when the soil moisture is not good, it is difficult to drill holes, the holes are easy to collapse, and the depth of the holes is insufficient. Water, topdressing needs to be drilled again or topdressing directly into the transplanting hole may cause burnt seedlings, and it is inconvenient to collect water for irrigation during drought
