Abstract
The embodiment of the utility model discloses a band type relay intercropping wheat no-tillage sowing and fertilizing machine for a hilly dry land. The machine comprises a rack, an auxiliary rack, a land wheel and four sowing boots, wherein the rack is provided with a seed box and also comprises a fertilizer box and four fertilizer boots, and the four sowing boots and the four fertilizer boots are horizontally arranged. According to the band type relay intercropping wheat no-tillage sowing and fertilizing machine for the hilly dry land, disclosed by the utility model, the sowing and the fertilizing can be carried out simultaneously under a no-tillage condition; since the band type relay intercropping wheat no-tillage sowing and fertilizing machine for the hilly dry land, disclosed by the utility model, is provided with only four sowing boots and four fertilizer boots, the machine can be driven by an enclosure of a small-sized tractor as the needed driving power for driving the machine is small, and the landforms of mountain lands and hills can be adapted; and thus, the band type relay intercropping wheat no-tillage sowing and fertilizing machine for the hilly dry land, disclosed by the utility model, is suitable for the hill landform and can be used for fertilizing and sowing simultaneously under the no-tillage condition.
Description
Technical field
The utility model relates to agricultural machinery technological field, more particularly, relates in particular to nonirrigated farmland, a kind of hills belt interplanting wheat no-tillage seeding fertilization machine.
Background technology
The southwest is China the third-largest wheat advantage producing region, contains Sichuan, Chongqing, Yunnan, Guizhou 4 provinces and cities, and this region topography rises and falls, and geographical relief is main with mountain region and hills, and the plot is narrow and small, and infrastructure such as road, water conservancy are poor, mechanized operation inconvenience.Because this district heat condition is three ripe deficiencies, two ripe having a surplus, so more than be main with the intercropping and interplanting plantation, " wheat/soybean " and " wheat/sweet potato " is the interplanting cropping pattern of promoting mainly.Spacing sleeve cropping has been inherited the fine tradition of China's cropping system, have to improve land utilization efficiency, increase plurality of advantages such as annual grain yield, but also exist technical sophistication, recruitment many, be not easy to drawbacks such as mechanization, planting cost height, benefit is low.Under the situation that current rural laborer shifts in a large number, the agricultural workforce is becoming tight day, Wheat Production is seen extensive more, yields poorly, and is of poor benefits, indivedual local phenomenons of letting a piece of farmland go to waste in the arable land that also occur.
Development mechanization sowing both can be liberated the labour, can guarantee seeding quality again, improved output, and make high yield and efficiently really obtain unification, be the only way of guaranteeing the hilly area sustainable development of agricultural production.In northern Plain, wheat is the crop of first realization entire mechanization of China.But north and south geographical relief, weather, soil heterogeneity are big, and north machinery also is not suitable for south, so must develop the small-sized machine that is applicable to southern hills, it then is the first step of its development that realization mechanization is sowed.Simultaneously, because how overcast and rainy southern wheat (particularly Sichuan) is between sowing time, soil cultivation inconvenience.And former study shows; Rotary tillage machinery is in whole ground process, and running up of its blade destroys greatly soil structure, and lacking no-tillage is whole Agricultural Development direction; But it is higher to the requirement of seeding machinery that no-tillage operation will be guaranteed seeding quality, difficult especially in the sticking heavy south of the soil texture.Existing seeding machinery does not satisfy the requirement of southern hilly area interplanting Wheat Production, mainly shows as following two aspects;
At first, though that domestic existing most of wheat no-tillage planters are sowed under no-tillage condition is effective, but its Dimensions is big and heavy, and the forerunner adopts large sized tractor to drive operation simultaneously, so only be adapted at operation on comparatively smooth, the spacious plot of physical features.Yet the southwest physical features is main with hills and mountain region all, and narrow, the poor flatness in plot can't satisfy its job requirements, and its sowing fabric width head and shoulders above the category of this area cover operation mode defined, therefore, can't be applied in the southwest.
Secondly, the mini-size tillage machine that use at present in the southern hills area, its power is little, and it is more shallow to ditch, and seed reveals easily to be broadcast, and is prone to cause disconnected ridge because of land wheel skids.In addition, its kind case is little, and fertilizer can only spread fertilizer over the fields prior to seeding; So mini-size tillage machine requires plowed soils at seeding operation as last, and it is excessive to soil stirring amount to turn over; And destroyed the structure of upper soll layer; Soil is prone to dehydration, and the seed germination process of emerging is obstructed, and dry year is bigger to the influence of emerging.Therefore should can't large tracts of land promote in the southwest by the combination facility, need further improve.
Therefore, how a kind of suitable hills and mountain topography being provided and nonirrigated farmland, the hills belt interplanting wheat no-tillage seeding fertilization machine with seeding operation of can under no-tillage condition, applying fertilizer simultaneously, is the technical barrier that those skilled in the art need solve.
