Abstract
The invention provides a cultivation method capable of increasing the amylopectin content in broomcorn. The optimal cultivation method is determined according to the accumulated biological characteristics of Milo starch, and particularly the cultivation method can increase the amylopectin content in broomcorn by over 11.1 percent through fine land preparation, in-time sowing, reasonable condensed planting, scientific fertilizer application and other measures. In the invention, the technique is simple in operation and suitable to be promoted.
Description
Technical field
The present invention relates to the arviculture field, relate in particular to a kind of cultivation method that improves the Chinese sorghum amylopectin content.
Background technology
Chinese sorghum is raised crop and brewing materials as important grain, has the photosynthetic efficiency height, hybrid vigour is strong, and drought resisting, waterlogging, salt tolerant alkali and multiple resistance such as barren-resistant are the staple food crops in China arid and semi-arid area.The sorghum seed content of starch is about about 75%, and wherein part sorghum variety amylopectin content accounts for more than 90%.The sorghum seed amylopectin content is the key factor of decision Chinese sorghum quality, and there is material impact the milled rice rate of seed, edible palatability and brewing quality aspect.The Chinese sorghum of China's production at present is mainly used in the high-quality liquor of brew, famous brands of wine such as the Maotai that has won fame both at home and abroad, five-Grain Liquor, Luzhou Old Cellar, Fenyang wine all form for the raw material brew with the Chinese sorghum, studies show that the height and the good and bad content that depends on amylopectin in the sorghum seed of distillation yield.Although cultivate some high starch sorghum hybrids in recent years, yet, also lack at present at the corresponding cultivation techniques that improves the Chinese sorghum amylopectin content, restricted the raising of high starch sorghum variety amylopectin content potentiality.
Summary of the invention
The purpose of this invention is to provide the cultivation method that improves amylopectin content in a kind of Chinese sorghum plantation, according to the biological property and the environmental impact factor of sorghum starch accumulation, by meticulous whole ground, begin sowing in good time, rational close planting, measure such as apply fertilizers scientifically improves the content of Chinese sorghum amylopectin.
The objective of the invention is to realize by the following method:
1, meticulous whole ground: promptly put in order the ground ridging in the fall behind the crop harvesting, adopt the rotovator stubble-cleaning, in conjunction with rake, drag chesson, level land accomplish dark, pine, carefully, spare, tilling depth 20cm, ridging then, row spacing is 60cm;
2, begin sowing in good time: after continuous 5 days daily mean temperatures were stablized by 10 ℃, daily mean temperature was accumulated in 10 days that reach after 426 ℃ and is sowed, and making Chinese sorghum be in daily mean temperature between the pustulation period is under the 19.5-20.5 ℃ of suitable temperature condition; Chinese sorghum sowing depth 3-5cm;
3, rational close planting: at 7.5 ten thousand strains-90,000 strains/hm
2Density range plant;
4, apply fertilizers scientifically: apply fertilizer to the subsoil prior to seeding, base fertilizer adopts farmyard manure, and fertilizing amount is 15000-20000kg/hm
2Execute seed manure during sowing, seed manure adopts diammonium phosphate and potassium sulphate, and fertilizing amount is diammonium phosphate 100-150 kg/hm
2, potassium sulphate 200-225 kg/hm
2Shooting stage imposes urea, and fertilizing amount is 260-390 kg/hm
2
The present invention compares with existing culture technique, has following advantage:
At the biological property of sorghum starch accumulation, determine best cultivation method, particularly by beginning sowing in good time, rational close planting, measure such as apply fertilizers scientifically can improve the Chinese sorghum amylopectin content more than 11.1%.The technology of the present invention is simple to operate, is suitable for promoting.
Embodiment
1, meticulous whole ground: promptly put in order the ground ridging in the fall behind the crop harvesting,, prolong the soil-ripening time in order to retaining and conserveing soil moisture.Adopt the rotovator stubble-cleaning, in conjunction with rake, drag chesson, level land and accomplish dark, pine, thin, even, tilling depth is advisable with 20cm.Ridging then, row spacing is advisable with 60cm, is accumulated in the moisture of topsoil with the guarantor.
2, begin sowing in good time: after continuous 5 days daily mean temperatures are stablized by 10 ℃, daily mean temperature is accumulated in 10 days that reach after 426 ℃ and is sowed, sorghum seed is between the pustulation period under the suitable temperature condition, the preference temperature of pustulation period is daily mean temperature 19.5-20.5 ℃, and suitable temperature of pustulation period can improve sorghum seed amylopectin content (for example areas of Shenyang is in sowing in-20 days on the 10th May).The Chinese sorghum sowing depth is advisable with 3-5cm, accomplishes the seed level unanimity during sowing, broadcasts row neatly to guarantee that seedling is neat, seedling even, seedling is strong.
3, rational close planting: plant with per hectare 7.5 ten thousand strains-90,000 strain density range.
4, apply fertilizers scientifically: apply fertilizer to the subsoil prior to seeding, base fertilizer adopts farmyard manure, and fertilizing amount is 15000-20000kg/hm
2Execute seed manure during sowing, seed manure adopts diammonium phosphate and potassium sulphate, and fertilizing amount is diammonium phosphate 100-150 kg/hm
2, potassium sulphate 200-225 kg/hm
2Shooting stage imposes urea, and fertilizing amount is 260-390 kg/hm
2
Through practical measurement: the Chinese sorghum amylopectin content of producing by this method can improve more than 11.1%.
Claims (1)
