Embodiment 1

[0020] A sesame drought-resistant and seedling-preserving cultivation technique. The sesame variety is Jinzhi No. 3. The test site is Xicun, Wanrong County, Shanxi Province. The test time is 2010. The planting area is a demonstration field of 16 mu. The spring of 2010 happened to have no rain, which is typical arid climate.

[0021] The specific planting method is as follows:

[0022] 1. Watering in winter: Plow the field after harvest in the autumn of 2009. After the plowing is completed, water once when the seasonal climate temperature is stable at minus 3 degrees. After watering, the irrigation water freezes in the soil;

[0023] 2. Preparation before sowing: Normal soil preparation began in the spring of 2010;

[0024] 3. Sowing: Observe the soil conditions, sow in time when the temperature and humidity reach the required range, the temperature is stable between 20°C and 23°C, the soil humidity is 20%—40% when sowing, and the sowing depth is 3cm , the sowing rate is 2 k...

Embodiment 2

[0027] The selected sesame variety is Jinzhi No. 2. The test site is Jiajiazhuang Village, Fenyang City, Shanxi Province. The test time is 2011, and the planting area is a demonstration field of 10 mu. The spring of 2011 happened to have no rain, which is a typical dry climate.

[0028] The specific planting method is as follows:

[0029] 1. Watering in winter: Plow the land after harvest in the autumn of 2010. After the plowing is completed, water once when the seasonal climate temperature is stable at minus 5 degrees. After watering, the irrigation water freezes in the soil;

[0030] 2. Preparation before sowing: Normal soil preparation began in the spring of 2011;

[0031] 3. Sowing: The temperature during the sowing season is stable at 18°C, the soil humidity is 20% when sowing, the sowing depth is 3cm, and the sowing rate is 2 kilograms of sesame seeds per mu;

[0032] 4. Ding seedlings, appropriate evening seedlings, 2-3 pairs of true leaf time seedlings, thinning seedl...

Embodiment 3

[0034] The selected sesame variety is Jinzhi No. 4. The test site is Xingyao Village, Wenxi County, Shanxi Province. The test time is 2011. The planting area is a demonstration field of 3 mu, and the planting is contracted by local farmers. The area was dry and rainless in the spring of that year, which is a typical arid area in Northwest China. The seedling emergence rate reached 90% after planting with this technology, which was 15% higher than that of the traditional technology. More than 9,000 seedlings per mu, realizing one-seeding full seedlings .

[0035] The specific planting method is as follows:

[0036] 1. Watering in winter: Plow the field after harvest in the autumn of 2010. After the plowing is completed, water once in winter when the climate temperature is minus 8°C. After watering, the irrigation water freezes in the soil;

[0037] 2. Preparation before sowing: Normal soil preparation began in the spring of 2011;

[0038] 3. Sowing: The temperature during the s...

Abstract

The invention discloses a cultivation technique, particularly discloses a cultivation technique for drought resisting and seedling protecting of sesame. The cultivation technique includes watering for one time after plowing after autumn harvest to guarantee irrigating water can be frozen in soil after watering, preparing soil normally before starting seeding, performing late thinning when 2-3 pairs of main leaves grow and performing late final singling when 3-4 pairs of the main leaves grow. The temperature in seeding seasons is stabilized above 18 DEG C, soil humidity during seeding ranges from 20% to 40%, seeding depth ranges from 2.5cm to 3.5cm, seeding quantity ranges from 2 kilograms / mu to 2.5 kilograms / mu, and row spacing of thinning is 5cm. By the cultivation technique, emergence of seedlings can reach 9000-10000 plants, and emergence rate can reach above 90%; labor is greatly reduced, and seed-consuming quantity is reduced; integrity, orderliness and healthy of the seedlings can be realized after all the seedlings are sowed, so that a good foundation is laid for production increase and good harvest; and working efficiency is improved, and the key problem in production of arid regions of northwest and north China is effectively solved.

Description

technical field [0001] The invention relates to a sesame cultivation technique, in particular to a sesame drought-resistant seedling conservation cultivation technique. Background technique [0002] Sesame is one of the six major oil crops in my country. It has high nutritional value, health value and beauty function. One tenth of the area, with a total output of 600,000 to 700,000 tons, accounting for a quarter of the world's total output, and its per unit yield and total output both rank first in the world. It is a dominant crop in the adjustment of agricultural structure and a traditional foreign exchange earning crop for export . In the past ten years, domestic sesame consumption has risen sharply, with an annual consumption of more than 800,000 tons, of which 200,000 tons depend on imports, changing from an exporting country to an importing country. [0003] China's sesame is distributed all over the country. According to the distribution area and production characteris...
