Description
Technical field
The utility model is related to agricultural machinery technological field, is risen more particularly, to a kind of peanut for summer sowing peanut
Ridge tectorial seeder.
Background technology
China is the first big country of peanut annual production and outlet, and 3.3 hundred million mu of whole world peanut area, 33,070,000 tons of total yield is single
Produce 89 kgs/acre.70,000,000 mu of China peanut area, accounts for global 1/5th, occupies second；12,630,000 tons of total yield, accounts for
Global 40%, occupy first；197 kgs/acre of per unit area yield, is 2.2 times of world average level.
The Spring Peanut that China's general planting is harvested for one time each year, because land utilization ratio and annual economic benefit are relatively low, gradually sends out
Exhibition is the cropping pattern of the two crops a year based on cornfield interplanting, has taken into account Foodgrain and oilseed production, improves annual benefit.
But wheat and peanut interplant there is also interplant it is time-consuming take a lot of work, seeding quality is poor, uneven emergence, be difficult to ensure that density, seedling
Growing way is weak, yield poorly, poor quality and the problems such as inconvenient do mechanization operation, into after 21st century, with wheat yield
The raising of level and the popularization of combined wheat harvester, cornfield interplanting peanut seem and are more difficult to adapt to.Thus, it is ensured that peanut industry
Sustainable and healthy development, must just explore the new cultivation mode of peanut production, improve field machinery operating rate, and reduction is produced into
This, realizes high-yield and high-efficiency, increases farmers' income.
At present, direct-seeding peanut after small wheat harvest is implemented, the problems such as can not only solve wheat and peanut interplant seeding quality difference, Er Qiebian
Mechanization is realized in the whole process such as wheat mechanized harvest and peanut site preparation, sowing, fertilising, results.Implement live flower after small wheat harvest
It is raw, first wheat stubble and stalk in field etc. can be smashed using rotary cultivator after wheat harvest and return soil, peanut seeding machine sowing is then used again
Cultivate peanut.But peanut ridging tectorial seeder in the market is designed to coordinate spring sowing peanut technology, its ridging dress
It is set to a pair inside ploughshares digged, although wheat stubble and stalk after wheat harvest in field etc. are crushed by rotary cultivator and return soil,
It is different in size after but wheat stubble and stalk are pulverized, still can be by during the ploughshares inwardly digged for a pair are advanced forward
Gradually hang on ploughshare, influence normal work and the ridging effect of ploughshare, cause the current peanut ridging tectorial seeder cannot be
Direct-seeding peanut in field after wheat harvest.
Therefore, existing peanut ridging tectorial seeder how is improved so that live in the field that it can be after wheat harvest
Peanut is the technical problem of those skilled in the art's urgent need to resolve.
Utility model content
The purpose of this utility model is to provide a kind of peanut ridging tectorial seeder for summer sowing peanut, the flower
