Description
Technical field
The present invention relates to soil conditioner technical fields, and in particular to a kind of water conservation fertilizer changes acid type mountain plateau red soil improving agent
And its application.
Background technique
Red soil is distributed mainly on the middle part of Yunnan Guanyuan, between 24 ° -26 ° of north latitude, 1500-2400 meters of height above sea level of remaining it is high
Former face, the low mountain of lake rim and hills.In addition, Yi Autonomous Prefecture of Liangshan that the Sichuan Province west and south and Yunnan are adjoined and Panzhihua
Also there is fragmentary distribution in the mountainous regions such as city.
According to Yunnan Province's data, the forest cover degree of mountain plateau khoai is 5 percentage points lower than the whole province at present, and deserted mountain barren hill is than complete
It saves 8 percentage points high.Mountain plateau red soil it is existing arable land 626.1 ten thousand mu, wherein Yunnan just accounts for 559.2 ten thousand mu, be the whole province's grain, cigarette, oil,
The main producing region and high yield area of fruit mulberry and vegetables.But in existing arable land, middle-and-low-yielding fields account for 80% or so, and effective irrigation area only accounts for
1/3.As long as the comprehensive development and utilization potentiality of mountain plateau red soil are huge it can thus be seen that agriculture management management measure is proper.
Mountain plateau khoai is up to 6 months dry seasons because it exists, and significantly limits mentioning for arable land multiple crop index and winter crops per unit area yield
Height makes winter higher temperature and stronger illumination be difficult to play a role, becomes the limiting factor of planting industry sustainable development.Therefore
Exploitation is directed to the water-retaining agent of mountain plateau red soil, very necessary for the water conservation of mountain plateau red soil.
Current China, arable land, red earth area acidification phenomenon is universal, all causes biggish shadow to agricultural production and ecological environment
It rings.Therefore, it adopts an effective measure and acidification red soil is improved and repaired, to protection agroecological environment and ensure agricultural product
Safety in production and agricultural sustainable development have important Significance for Environment and economic benefit.It is traditionally main both at home and abroad to use list Shi Shi
The alkaline matters such as ash carry out soil acidification improvement, but the side effect of single lime excessive be easy to cause soil hardening and multiple acidification existing
As asking.
Summary of the invention
The purpose of the present invention is to provide a kind of water conservation fertilizers to change acid type mountain plateau red soil improving agent and its application, can promote soil
The increase of organic substance in earth, retain water and nutrients performance is good, can long-term adjustment soil aciditiy, and not will cause soil hardening, it is right
