Embodiment Construction

[0024] The inventor implements the present invention in Tengchong County, Yunnan Province, specifically as follows:

[0025] 1. Layout: First, select a suitable planting area. The layout of the area must be below 1500 meters above sea level, otherwise there will be low temperature hazards. Second, we must adhere to the rice and tobacco rotation system.

[0026] Table 1 Effects of different altitudes on rice transplanting time

[0027]

[0028]

[0029] Tobacco needs to implement crop rotation measures. Rice-tobacco crop rotation is used when planting tobacco in Tengchong paddy fields. From the perspective of economic benefits, timely transplanting of rice is necessary, and delaying the time of rice transplanting will cause a decline in rice output. It is known from Table 1 that when the altitude is above 1600 meters, the transplanting period of rice will be delayed by 29 days, which is extremely unfavorable to the growth of rice. Considering the reality of Tengchong (s...

Abstract

The invention relates to a method for planting cured tobacco in a hot area from May to September, belonging to the technical field of agriculture. The invention not only develops the technology, but also cooperates with a reasonable cultivation mode for cultivation, thereby effectively solving the problem of insufficient temperature in winter planting technology. The method for planting cured tobacco in a hot area from May to September is used for researching planting altitude, planting density, seedling raising modes, nitrogen application amount, antifreezing measures, irrigation regime, and the number of days for reserving tobacco, thereby solving the technical problems of land area shortage, and confliction between the hot-area cured tobacco planting technology from May to September and the climate from October to next April. Meanwhile, the cured tobacco is planted below the film instead of above the film, and idle soil in winter is utilized to develop the method for planting cured tobacco in a hot area from May to September, thereby increasing the land-use ratio and enhancing the economic benefit of farmers. The method for planting cured tobacco in a hot area from May to September has the advantages of less investment, high effect taking speed, high yield, high efficiency and the like, and can be used for large-scale production.

Description

Technical field: [0001] The invention relates to a method for planting flue-cured tobacco in small spring season in a hot zone, belonging to the technical field of agronomy. Background technique: [0002] The hot zone mainly refers to the low-heat valley area at an altitude of 1000-1500 meters, with an annual average temperature of 14.9°C, the coldest month being January with an average temperature of 7.7°C, the hottest month being August with an average temperature of 19.8°C, and a frost-free period of 234 days. The average annual sunshine is 2069 hours, the average relative humidity is 79%, the climate has four seasons, hot summer, concentrated rainfall, warm and pleasant autumn, winter and spring, less precipitation, sunny all year round, and small annual temperature difference. [0003] The flue-cured tobacco planting and development technology in the small spring season in the hot area can make full use of the light and heat conditions in the low-heat valley area, winte...
