Abstract

The invention provides a planting method of selenium-enriched millets in moderate temperature arid and semi-arid area with the altitude of 1500 to 2100 m. The planting method comprises the following steps: harvesting preceding crops, ploughing, carrying out stubble chopping and deeply ploughing in early spring; carrying out rotary tillage and soil preparation, crushing soil and flattening, and carrying out film mulching and moisture conservation; before rotary tillage and soil preparation are carried out, applying a composting fertilizer, a nitrogen fertilizer, a phosphorus fertilizer, a potassium fertilizer, and a humic acid selenium fertilizer; coating seeds by using a seed coating agent or carrying out seed dressing by using 50 percent of carbendazim, wherein the seed coating agent is prepared from zinc sulfate, ammonium molybdate, manganese sulfate, a water retaining agent, the carbendazim and a film-forming agent; the sowing amount is 7.5 to 11.2 kg per hectare, the line spacing is 20 cm and the sowing depth is 2.5 to 4.5 cm; dressing urea at a booting stage or spraying monopotassium phosphate and / or urea on foliage. The yield of the millets can reach 6000 to 8500 kg per hectare, the spike number reaches 675 thousand spikes per hectare, thousand grain weight is 3.3 to 3.7 g and the selenium content of millet products is 0.1 to 0.2 mg / kg.

Description

technical field [0001] The invention relates to the field of planting agricultural products, in particular to a method for planting selenium-enriched millet. Background technique [0002] Millet is one of the main crops in the upland areas of northern my country, and it is the cereal crop with the strongest drought resistance and wide adaptability. Millet is widely distributed in my country, but it is mainly distributed in the northern provinces between 32-48 degrees north latitude and 108-130 degrees east longitude. However, due to unfavorable factors such as remote planting areas, pests and birds, and poor weather conditions, the yield of millet production areas varies greatly, which limits the good development prospects of the millet production industry. In the millet planting process, in order to improve the yield and quality of millet, it is necessary to strengthen the management of the millet cultivation process, control the cultivation technology, make preparations b...
