Embodiment 1

[0019] A method for transplanting flue-cured tobacco with double rows of concave ridges and large nests with deep butterfly-shaped rain collection and drought resistance, comprising the following steps:

[0020] (1) Soil preparation and ridging: plow the kang in winter in the first year, prepare the land 2-3 months before the ridging in the next year, and do ridging according to the double-row concave ridge method 20 days before transplanting;

[0021] (2) Make a large nest: Make a nest on the ridge according to the distance between plants and rows. The depth of the nest is 20cm, and it is half-conical in shape. The diameter of the upper mouth is 25cm, and the diameter of the lower bottom is 15cm;

[0022] (3) Fertilizing mixed soil: Spread the base fertilizer evenly in the nest, then backfill the soil dug out during the nesting into the nest, mix the soil and fertilizer evenly, and repair the ridges that were damaged during the nesting, and backfill the soil along the top edge...

Embodiment 2

[0026] A method for transplanting flue-cured tobacco with double rows of concave ridges and large nests with deep butterfly-shaped rain collection and drought resistance, comprising the following steps:

[0027] (1) Soil preparation and ridging: plow the kang in winter in the first year, prepare the land 2-3 months before the ridging in the next year, and do ridging according to the double-row concave ridge method 20 days before transplanting;

[0028] (2) Make a large nest: Make a nest on the ridge body according to the distance between plants and rows. The depth of the nest is 20cm, and it is half-conical in shape. The diameter of the upper mouth is 28cm, and the diameter of the lower bottom is 18cm;

[0029] (3) Fertilizing mixed soil: Spread the base fertilizer evenly in the nest, then backfill the soil dug out during the nesting into the nest, mix the soil and fertilizer evenly, and repair the ridges that were damaged during the nesting, and backfill the soil along the top...

Embodiment 3

[0033] A method for transplanting flue-cured tobacco with double rows of concave ridges and large nests with deep butterfly-shaped rain collection and drought resistance, comprising the following steps:

[0034] (1) Soil preparation and ridging: plow the kang in winter in the first year, prepare the land 2-3 months before the ridging in the next year, and do ridging according to the double-row concave ridge method 20 days before transplanting;

[0035] (2) Make a large nest: Make a nest on the ridge according to the distance between plants and rows. The depth of the nest is 20cm, and it is half-conical in shape. The diameter of the upper mouth is 30cm, and the diameter of the lower bottom is 20cm;

[0036] (3) Fertilizing mixed soil: Spread the base fertilizer evenly in the nest, then backfill the soil dug out during the nesting into the nest, mix the soil and fertilizer evenly, and repair the ridges that were damaged during the nesting, and backfill the soil along the top edge...

Abstract

The invention relates to a rainwater harvesting and drought resisting transplanting method adopting butterfly-shaped double-row concave ridges with large pits for deep application and used for flue-cured tobacco. The method comprises the following steps: (1), land is prepared and ridging is performed; (2), large pits are dug in ridge bodies according to the plant spacing requirement, each pit is 20 cm deep and is in a half turbination shape, the diameter of the upper port is 25-30 cm, and the diameter of the bottom is 15-20 cm; (3), fertilizer is applied and mixed with soil: base fertilizer is spread to the large pits uniformly, then soil dug out during pit digging is refilled to the pits, the fertilizer and the soil are mixed uniformly, the ridge bodies which are damaged during pit digging are repaired simultaneously, the upper edge of the refilling soil is slightly lower than the ridge bodies by 2-5 cm, and a butterfly shape is formed; (4), film mulching and earthing up are performed; (5), transplanting is performed. The method can solve the problems of effective rainfall deficiency and large drought resisting difficulty during flue-cured tobacco transplanting in areas with serious spring drought, saves labor and time, can increase the survival rate of transplanted flue-cured tobaccos, promote early growth and quick tillering of tobacco plants, improve the yield and quality of tobaccos and can be widely applied to crops such as pepper, eggplant, tomatoes and the like which need transplanting.

Description

technical field [0001] The invention belongs to the field of flue-cured tobacco cultivation methods, and in particular relates to a flue-cured tobacco double-row concave ridge large nest deep application butterfly-shaped rain-collecting and drought-resistant transplanting method. Background technique [0002] At present, the tobacco planting area mainly adopts the single-row ridge transplanting method. The main problem is that when the soil moisture (moisture) is insufficient, the film cannot be covered, because it is difficult for rainwater to enter the ridge after the film is covered, which affects the timely transplanting of flue-cured tobacco. In order to solve this problem, in recent years, some tobacco areas have used the double-row concave ridge film-covered transplanting method. This method has the following advantages: First, after the double-row concave ridge is covered, the rainfall can be received through the concave ridge, supplementing The moisture in the rid...
