Abstract

The invention discloses a season-divided efficient sweet potato planting method suitable for the three-dimensional climate of Yunnan and Qian areas. According to the method, the stereoscopic climate of the Yunnan Qian area is utilized, seedlings are raised in advance in the geothermal valley area, transplanting is carried out in seasons, and harvesting and marketing are carried out in batches, so that the risk of outbreak of plant diseases and insect pests is reduced, the sweet potatoes are brought into the market early, centralized marketing is avoided, the marketing time is 50-80 days earlier than that of a traditional sweet potato planting mode, the competition of the sweet potatoes brought into the market in advance is small, and the unit price is high. Moreover, the season of concentrated outbreak of plant diseases and insect pests is staggered, so that less chemical pesticide is used in the planting process, even the chemical pesticide can not be used, the planting cost is saved, the quality of the sweet potatoes is improved, and the market competitiveness is improved.

Description

Sweet potato season-divided efficient planting method suitable for three-dimensional climate in Yunnan and Qian region

Technical Field

The invention relates to the technical field of agriculture, in particular to a season-divided efficient sweet potato planting method suitable for the three-dimensional climate of Yunnan and Qian areas.

Background

The Yunnan Qian area is a main production area of the Chinese sweet potatoes, the traditional planting mode generally arranges seeds and grows seedlings in the late 3 th ten days, transplants in the early 6 th days, and centralizes the seedlings on the market in 10 months and 11 months, the growth season of the transplanted sweet potatoes has a positive sweet potato pest peak period, the pest and disease damage is large, the loss and weight loss are high, the cost of the needed chemical pesticide is high, and the market sweet potatoes have large market quantity, low unit price and large competition when being centralizedly marketed in 10 months and 11 months.

Disclosure of Invention

The purpose of the invention is: the season-divided efficient sweet potato planting method suitable for the three-dimensional climate of the Yunnan and Qian area is provided, the risk of plant diseases and insect pests is reduced, the time of the sweet potatoes appearing in the market is advanced, the problems that the unit price of the sweet potatoes in the Yunnan and Qian area is low in the season of the market, the competition is large, the planting benefit is poor and the like are solved, and the risk of the plant diseases and insect pests is reduced.

The invention is realized by the following steps: the season-divided efficient sweet potato planting method suitable for the three-dimensional climate of the Yunnan Qian area comprises the following steps:

1) early seedling in late middle and late 1 month: in the middle and late ten days of 1 month, sowing seeds in sunny days in the low-altitude valley region of Yunnan and Qian, and raising seedlings in advance;

2) transplanting in different seasons: transplanting and planting in batches by using seedlings bred in advance from 20 days in 3 months, and transplanting once every 20 days until 7 days, and stopping transplanting;

3) harvesting in batches: harvesting and marketing in batches from 7 months and 20 days, and continuously harvesting and marketing according to the season-divided transplanting condition.

Due to the adoption of the technical scheme, compared with the prior art, the method utilizes the stereoscopic climate of the Yunnan Qian area, seedlings are raised in advance in the geothermal valley area, transplanting is carried out in seasons, and sweet potatoes are harvested in batches and listed, so that the risk of outbreak of plant diseases and insect pests is reduced, the sweet potatoes are listed on the market in advance, the sweet potatoes are prevented from being listed on the market in a centralized manner, the sweet potato planting time is 50-80 days earlier than that of the traditional sweet potato planting method, the competition is small, and the unit price is high. Moreover, the season of concentrated outbreak of plant diseases and insect pests is staggered, so that less chemical pesticide is used in the planting process, even the chemical pesticide can not be used, the planting cost is saved, the quality of the sweet potatoes is improved, and the market competitiveness is improved.

Detailed Description

The embodiment of the invention comprises the following steps: a season-divided high-efficiency sweet potato planting method suitable for the three-dimensional climate of Yunnan Qian region,

1) early seedling in late middle and late 1 month: in the middle and late ten days of 1 month, in the low-altitude valley areas of Yunnan and Qian (the sparkling town of Ziyun county, the Lutuo county, the Li Ping county, the Yangjiang county and the like), sowing in fine days is selected, and seedlings are grown in advance;

2) transplanting in different seasons: transplanting and planting in batches by using seedlings bred in advance from 20 days in 3 months, and transplanting once every 20 days until 7 days, and stopping transplanting;

3) harvesting in batches: harvesting and marketing in batches from 7 months and 20 days, and continuously harvesting and marketing according to the season-divided transplanting condition.

The specific implementation of this technique is as follows:

1. the implementation time is as follows: in 2019, the implementation site: guizhou province purple cloud county, planting variety and scale: purple cloud red core potato, 500 mu.

The implementation condition is as follows: seeding and seedling raising are carried out in a sparkling town (height of 628 m) in purple cloud county of Guizhou province in 20 days in 1 month in 2019, and transplanting is carried out in a country with limestone in purple cloud county of Guizhou province in 3 months and 20 days in 2019 in seasons (height of 1359 m).

TABLE 12019 years Guizhou province purple cloud county purple cloud red core potato quartered transplanting result statistical table

Transplanting yield by seasons: the yield is 807 jin/mu (122 days in the growth period) when the rice is listed on 20 days in 7 months in 2019, 1200 jin/mu (110 days in the growth period) in the early 8-9 middle days in 2019, and 1800 jin/mu (100 days in the growth period) after the late 9 months in 2019.

2. Planting results in a traditional planting mode:

2. planting time: in 2019, the planting place: the elevation 1341 m of the country of white rock in purple cloud county of Guizhou province, the planting variety and scale: purple cloud red core potato, 3000 mu.

Planting conditions are as follows: the conventional transplanting time of sweet potatoes in Guizhou province, purple cloud county, 2019, one year and one season is about 6 months and 20 days, the harvesting time is about 10 months and 25 days, the average yield per mu is about 1900 jin, and the average purchase price is about 2.0 yuan/jin.

3. Comparison of the patent of the invention with the traditional planting method in the same area

In Guizhou province purple cloud county, the yield value per mu of sweet potatoes planted by the traditional sweet potato planting method is about 3800 yuan, the time of sweet potatoes concentrated on the market is staggered, the sweet potatoes are listed in the market early, the economic value of the sweet potatoes is improved, the yield value per mu reaches 5000 + 8000 yuan, sweet potato marketing seasons are staggered, the vacancy of the sweet potatoes in the summer market is made up, people's summer vegetable baskets are enriched, and compared with the traditional planting method, the advantages of the method are very obvious.
