Embodiment 1

[0020] The method for crop rotation of short pavilion flying canopy and tobacco, its steps are as follows:

[0021] 1. Land selection and arrangement: Select the fertile sandy soil land at an altitude of 1500 meters. At the end of March, deep plow the land, combine with leveling the land, apply 4500 kg of farmyard manure per mu, mix evenly in the cultivation layer, and make it 80cm wide and 20cm wide. High soil moisture, waiting to plant tobacco; after the harvest of the big spring tobacco in late August, clear the field, plow the land, combine with leveling the land, apply 2500 kg of farmyard manure per mu, mix evenly in the cultivation layer, and make a 120cm wide, 20cm high soil moisture, to be planted short pavilion flying canopy.

[0022] 2. Crop rotation:

[0023] (1) In the spring season at the end of March, dig a pond in the shape of a character on the moisture surface of the tobacco field to be planted after step 1. The depth of the pond is 15-20cm, the distance betw...

Embodiment 2

[0027] Embodiment 2 is the same as Embodiment 1 except that the following measures are different, and will not be repeated here.

[0028] 1. Land selection and arrangement: the altitude is 1,100 meters. At the end of April, 5,000 kg of farmyard manure was applied to each mu, and the soil moisture was 100 cm wide and 30 cm high. Tobacco was to be planted; Apply 3,000 kg of farmyard manure per mu to the land, with a moisture content of 140 cm wide and 30 cm high, and short pavilions and flying canopies will be planted.

[0029] 2. Crop rotation:

[0030] (1) In the spring season at the beginning of April, dig a pond in the shape of a character on the moisture surface of the tobacco field to be planted after step 1. The depth of the pond is 15-20cm, the distance between plants is 60cm, and one tobacco seedling is transplanted in each pond; At the tobacco seedling stage, loosen the soil and remove weeds every 15 days, combined with loosening the soil and removing weeds, topdressi...

Embodiment 3

[0033] Embodiment 3 Except that the altitude is 1800 meters, other steps are the same as in Embodiment 1, and will not be repeated here.

[0034] The effects of each embodiment are shown in Table 1.

[0035] The effect of the embodiment is compared with the total value of the fresh products harvested for 3 times in Duanting Fei Peng.

[0036] In Table 1, wheat, potato, broad bean, and pea are rotated with tobacco respectively according to the prior art, and will not be repeated.

[0037] The prices in the table are calculated based on the current market price: the unit price of short pavilion flying canopy is 3 yuan / kg; the unit price of wheat is 2.8 yuan / kg; the unit price of potato is 0.8 yuan / kg; the unit price of broad bean is 3.5 yuan / kg; the unit price of pea is 3.5 yuan / kg.

[0038]

[0039] The above examples show that:

[0040] 1. The present invention is beneficial to the prevention and control of diseases, insects and weeds; it is beneficial to the balanced use...

Abstract

The invention relates to a method for crop rotation of erigeron breviscapus and tobacco and belongs to the technical field of commercial crop planting. The method comprises the following steps: transplanting a tobacco seedling in a sandy soil with an elevation of 1100-1800 m, wherein the crop rotation time is the spring season ranging from the end of March to the beginning of April each year, and the base fertilizer is 4500-5000kg farm manure / mu; and from the last ten-day period of August to the beginning of September, transplanting erigeron breviscapus in the late autumn season after the tobacco is harvested, wherein the base fertilizer is 2500-3000kg farm manure / mu. By using the method, the crop rotation of two commercial crops with different root system extending lengths, namely, erigeron breviscapus and tobacco, is achieved, thereby being beneficial to prevention and control of diseases, insect pests and weeds and being beneficial to balanced utilization of soil nutrition. The method provided by the invention is a tobacco and medicament crop rotation mode capable of effectively improving soil utilization ratio, and amplification of newly increased output value per mu is ****, thereby being beneficial to promotion of regulation of an industrial structure of agriculture.

Description

technical field [0001] The invention belongs to the technical field of planting economic crops, and in particular relates to a method for cropping with short pavilion fly canopy and tobacco. Background technique [0002] Short tcap flying canopy ( Erigeron breviscapus (Vant.) Hand.-Mazz.) is a perennial herb of Compositae, also known as Erigeron breviscapus and Erigeron breviscapus. It is mainly distributed in open hillsides, grasslands or forest margins of alpine and subalpine mountains at an altitude of 1200-3500. The whole herb is pungent, slightly bitter, warm, and has the effects of expelling wind and dehumidification, activating collaterals to relieve pain, invigorating the spleen and eliminating stagnation. It is used for paralysis, rheumatic joint pain, toothache, stomach pain, infantile malnutrition, poliomyelitis and sequelae of meningitis. It is an important raw material plant for Chinese patent medicines in the treatment of cardiovascular diseases in my countr...
