Embodiment 1

[0020] Embodiment 1 (dry year)

[0021] A method for planting highland barley against seasonal drought in Tibet, comprising the following steps:

[0022] (1) Soil preparation, irrigation and fertilization

[0023] Tibet Chunqing farmland needs to be sprayed 1-2 times after the first stubble crops are harvested, when the weeds grow out in the farmland fallow period in mid-September 2014, with an interval of 7 days between each time, and then spray herbicide once at the end of March 2015; Irrigate on April 10 and water thoroughly; plow the ground on April 15, use mechanical deep plowing, plow 30-40cm deep, pick up the field weeds, apply more than 2000kg of high-quality organic fertilizer per mu, and apply sufficient inorganic fertilizers Fertilizer, urea 15kg / mu, diammonium phosphate 15kg / mu, potassium chloride 6kg / mu, adopt the "one shot" fertilization method, apply organic fertilizer and inorganic fertilizer into the soil at one time as base fertilizer, and use a rotary tille...

Abstract

The invention discloses a drought resistant planting method of highland barley, and relates to the technical field of agricultural planting. The method comprises the steps of soil preparation, irrigation and fertilization in the earlier stage of sowing, conducting drought-resistant treatment on highland barley seeds, and conducting soil moisture conservation treatment on soil after sowing; conducting weeding through intertillage in the elongation stage of highland barley during the middle period of sowing, and irrigating the highland barley with a moisture measurement control method and adopting a water-retaining agent to conduct drought resistance and water conservation from the elongation stage of the highland barley to the pustulation period; spraying the highland barley with a leaf fertilizer from the booting stage of the highland barley to the pustulation period in the earlier stage of sowing. According to the drought resistant planting method of the highland barley, the soil permeability and water-retaining property can be improved, and ineffective physiological water consumption of crops is reduced and water-saving irrigation is achieved through soil moisture control; meanwhile, the method can fully meet the physiological water requirement of the highland barley, irrigation water is reduced, the drought resistance of the highland barley is improved, the rate of emergence, effective tillering, seeds per ear and thousand seed weight of the highland barley are increased, and the method has obvious drought resistance and yield increase effects on the highland barley.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a planting method for highland barley to resist drought. Background technique [0002] Most places in Tibet have low annual rainfall (below 400 mm), but annual evaporation is high (above 2000 mm), and the distribution of rain is uneven. More than 70-80% of the amount. Judging from the rainfall distribution in Tibet, there is drought and little rain in the early stage of Tibetan highland barley growth, and abundant rain in the later stage. Spring drought and summer drought will hinder the normal growth and development of highland barley. Climate warming has brought forward the sowing date of highland barley in Tibet, and the altitude suitable for sowing highland barley has increased. At the same time, since most agricultural areas in Tibet belong to arid and semi-arid climate zones, the drought hazards of highland barley have increased year by year. During the growth and dev...
