Description

A kind of no-tillage kind of wheat, fertilizer, medicine are the same as machine of broadcasting

Technical field

The utility model relates to a kind of no-tillage kind of wheat, fertilizer, medicines with machine is broadcast, and belong to the technical field of agricultural machinery.

Background technique

Wheat is the second largest staple food crop that China is only second to rice, and planting area is vast, and cultivated area is more than 2.4 Hundred million hectares.Optimization Planting technology, improving utilization rate of fertilizer is the key that wheat good harvest high yield, realizes weight-reducing synergy.Agricultural machinery Development, the planting patterns for the wheat that thoroughly taken on a new look makes the planting patterns of wheat apply to broadcast and be changed into machine by traditional livestock, manually Tool, which is applied, to be broadcast, and is changed by labor-intensive poly-talented, greatly optimizes traditional wheat planting mode, is to improve fertilizer utilization The effective means of rate, seed manure for weat are exactly prominent representative therein with machine of broadcasting.Seed manure for weat with machine of broadcasting by fertilizer and seed together It applies and is multicast in soil, compared with traditional fertilizing method, seed manure can effectively ensure that fertilizer below seed by crop with broadcasting Root system fully absorb, reduce fertilizer earth's surface loss and volatilization, utilization rate of fertilizer can be improved 10%-20%.It is improving While crop yield, broadcast technology not only simplifies planting type to seed manure together, also reduces labour cost, adapts to modern planting industry collection The requirement of reduction development.

Although seed manure planter has the above advantages, existing seed manure planter does not have trench digging, sowing, fertilising generally With the integrated function of suppression；And traditional seed manure planter can only often carry out solid fertilising, not be able to satisfy liquid fertilization It needs, generalization degree is low；In addition, existing seed manure planter is to apply fertilizer to broadcast in seed vertical lower, although solving root It is absorption problem, but fertilizer is excessively close apart from seed, in the case where soil moisture content is bad, compound fertilizer, diammonium, urea, sulphur coating The fertilizer that urea etc. is present in seed vertical lower is easy to volatilize, and causes nutrient that cannot be fully absorbed by root system, utilization rate of fertilizer Low, volatile substances therein such as free ammonia etc. also will cause burn seedlings phenomenon.

Chinese utility model patent application CN201510006429.6 discloses a kind of wheat subsoiling rotary tillage layer by layer manuring point Band seed broadcaster, the seed broadcaster once into the achievable subsoiling in ground, deep layer apply deeply slow-release fertilizer, etc. it is deep spread fertilizer over the fields base manure, etc. it is deep scatter seeds, The operations such as earthing, suppression effectively improve utilization rate of fertilizer, reduce manuring late operation, and energy conservation is high-efficient.But the wheat subsoiling Rotary tillage layer by layer manuring point is only available for applying for solid fertilizer with seed broadcaster and broadcasts, and can not achieve applying for liquid fertilizer and diseases prevention medicament With.

Chinese utility model CN201521070715.0 discloses a kind of salt-soda soil double-purpose fertilizer applicator, which applies Fertile machine, by the way that applicator boot, Seeding box, fertilizing box and pressing wheel link together, so that whole device is provided simultaneously with out Ditch, sowing, fertilising and overlay film function, and fertilizing box is divided into solid fertilizing box and liquid fertilization case, so that fertilizing box both may be used , can also be with applying liquid fertilizer to apply solid fertilizer, and liquid fertilization case can also be used to sprinkle water, and realize functional diversities.But the salt Alkali the fertilising step of double-purpose fertilizer applicator be after trench digging and sowing, fertilizer is applied above seed, and the effective of nutrient is unfavorable for It utilizes.

Seed manure planter is later in China's development, especially broadcasts technology using upper, present no-tillage seed manure is same in wheat, also Soil issues, the soil moistures content that still rely on soil such as hardening and soda acid cannot be fundamentally solved by a machine apply broadcasting.
