Relay intercropping planting and returning utilization method for Vicia villosa in cold tobacco area

A technology of light-leaf sagebrush and cooling, which is applied in fertilization methods, applications, tobacco cultivation and other directions, can solve the problem that it is difficult to meet the accumulated temperature requirements of sagebrush, the upper tobacco leaf curing loss rate is high, and the tobacco leaves turn yellow layer by layer during the mature stage. It can improve the soil quality of tobacco fields, increase the growth period of the field, and improve the germination rate of seeds.

Problems solved by technology

Tobacco leaf production in cold and cool tobacco areas often faces the problem of "low temperature at both ends", that is, low temperature during the transplanting period and low temperature during the maturity period, and it is difficult for the tobacco leaves to fall yellow layer by layer during the maturity period.
In addition, the winter temperature is low in cold and cool tobacco areas, and it is difficult to sow green manure crops of purple sweet potato after the harvest of flue-cured tobacco to meet the accumulated temperature demand of normal growth and development of purple sweet potato

Embodiment 1

[0031] A method for intercropping, planting and returning to the field of purple sweet potato in a cold and cool smoking area, comprising the following steps:

[0032] (1) Treatment of purple sweet potato seeds: before planting, place the seeds of purple sweet potato in the sun to dry for 1 day. After drying, mix the seeds and fine sand in a ratio of 2:1, put them in a woven bag, and rub them repeatedly for 6 Rub the seed coat in minutes, select seeds with salt water to remove floating debris on the water surface, pour off the salt water, rinse twice with water, soak the seeds once with ammonium molybdate solution, and finally mix the seeds with the rhizobia exclusive to Viola glabra at a ratio of 10:1 The ratio is mixed well, and it is advisable to add appropriate amount of water so that the rhizobia can attach to the surface of the seeds. After mixing well, the seeds can be sown.

[0033] (2) Tobacco field preparation and sowing: After harvesting the lower leaves of flue-cur...

Embodiment 2

[0039] A method for intercropping, planting and returning to the field of purple sweet potato in a cold and cool smoking area, comprising the following steps:

[0040] (1) Treatment of purple sweet potato seeds: before planting, place the seeds of purple sweet potato in the sun to dry for 2 days. After drying, mix the seeds and fine sand according to the ratio of 2:1, put them in a woven bag, and rub them repeatedly for 8 Rub the seed coat in minutes, select seeds with salt water to remove floating debris on the water surface, pour off the salt water and rinse with water 3 times, soak the seeds with ammonium molybdate solution 1 time, and finally mix the seeds with the rhizobia bacterium exclusive to P. glabrata at a ratio of 10:1 The ratio is mixed well, and it is advisable to add appropriate amount of water so that the rhizobia can attach to the surface of the seeds. After mixing well, the seeds can be sown.

Embodiment 3

[0047] A method for intercropping, planting and returning to the field of purple sweet potato in a cold and cool smoking area, comprising the following steps:

[0048] (1) Treatment of purple sweet potato seeds: put the purple sweet potato seeds in the sun to dry for 1.5 days before sowing. After drying, mix the seeds and fine sand according to the ratio of 2:1 and put them in a woven bag. Knead repeatedly for 10 days. Rub the seed coat in minutes, select seeds with salt water to remove floating debris on the water surface, pour off the salt water, rinse twice with water, soak the seeds once with ammonium molybdate solution, and finally mix the seeds with the rhizobia exclusive to Viola glabra at a ratio of 10:1 The ratio is mixed well, and it is advisable to add appropriate amount of water so that the rhizobia can attach to the surface of the seeds. After mixing well, the seeds can be sown.

Abstract

The invention discloses a relay intercropping planting and returning utilization method for Vicia villosa in a cold tobacco area. The method comprises steps as follows: Vicia villosa seed treatment, tobacco field soil preparation and sowing, fertilization management, water management, green manure turning and pressing and fertilization management of later-crop flue-cured tobaccos after green manure turning and pressing. By means of the Vicia villosa seed treatment, seed germination rate and emergence rate of the Vicia villosa can be effectively increased; by means of the fertilization management and the water management, growth and development of the Vicia villosa can be effectively promoted, and biomass of the Vicia villosa is increased; by means of the green manure turning and pressing treatment, the biomass of the overground part of the Vicia villosa can be effectively turned and pressed into a soil layer, and the Vicia villosa is promoted to be sufficiently decomposed and release nutrients; by means of the fertilization management of the later-crop flue-cured tobaccos after green manure turning and pressing, tobacco quality of the later-crop flue-cured tobaccos is improved. Comprehensively, the method has an obvious effect of increasing the biomass of the Vicia villosa as overwintering green manure in the cold tobacco area, improving soil quality of the tobacco field and improving tobacco quality of interplanting flue-cured tobaccos and the later-crop flue-cured tobaccos.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a method for intercropping, planting and returning to fields of purple sweet potato in cold and cool tobacco areas. Background technique [0002] Cold tobacco areas are the main body of tobacco leaf production in my country. For example, Qujing Zhaotong in northeastern Yunnan, Lijiang Dali in northwestern Yunnan, and Liupanshui in Bijie in northwestern Guizhou are all cold tobacco areas. Tobacco leaf production in cold and cool tobacco areas often faces the problem of "low temperature at both ends", that is, low temperature during the transplanting period and low temperature during the maturity period, it is difficult for the tobacco leaves to fall yellow layer by layer during the maturity period, the quality of fresh tobacco leaves in the field is poor, and the loss rate of the upper tobacco leaves is high. In addition, the winter temperature is low in cold ...
