Description
Technical field
The present invention relates to slow-release or control-release fertilizer technical fields, and in particular to a kind of controlled release Blending Fertilizer resistant to lodging for Direct-seeding Rice
Material, preparation method and application.
Background technology
South rice is one of most important cereal crops in China, and is broadcast live as a kind of original rice cropping mode,
It is gradually substituted after the appearance of rice transplanting technology.But since Direct-seeding Rice has the characteristics that saving of labor, laborsaving, cost-saving,
And Direct-seeding Rice can shorten breeding time without process of turning green after pull up seedlings plant injury and cultivation；Along with 1 year one season of kind, direct sowing of rice had enough
Time, seedling is not required to shorten the implantation time in big Tanaka, therefore, compared with rice transplanting technology, farming rich and influential family is more
Like using direct-seeding rice cultivation.At present in China, Direct-seeding Rice can increase Population to increase by increasing application rate
Yield, yield can reach rice transplanting quite or the level more than transplanting rice, therefore the development of Direct-seeding Rice cultivated area is swift and violent.But
There is easily lodging in Direct-seeding Rice plantation, on the one hand since seed imposes on soil surface, plant root is shallow, and bundle soil is not deep,
And thickness of sowing is excessive, the later stage easily lodges；On the other hand it is exactly improper fertilization, early period is more using available nutrient, easily
Making plant, rice basal internode causes late growth stage of rice lodging tolerance weaker away from elongation in mid-term over growth.Large area
Lodging can reduce the yield and quality of rice, and can not realize mechanical harvesting, increase harvest difficulty.Therefore, for previous original
Cause has the prior art and paddy rice planting method is studied to improve the situation resistant to lodging of rice, and for latter reason, it is existing
There is an urgent need for the new fertilizer of research and development, can effectively improve the lodging tolerance of Direct-seeding Rice, and can reduce top dressing number, improve fertilizer
Expect utilization rate, reduce dose.
The Chinese invention patent of Application No. 201710144850.2 discloses a kind of rice with nitrogen potassium slow-release function
Special fertilizer and its application are combined by nitrogen-potassium binary Controlled Release Fertilizer and other granulated fertilizers, and single fertilization extends nutrient in water
Time, although can meet the needs of paddy growth is to nutrient, nitrogen potassium content is than fixed (2 in nitrogen-potassium binary Controlled Release Fertilizer:
1), and in nitrogen-potassium binary Controlled Release Fertilizer nitrogen, K released phase are the same, and adaptation rice varieties are single, are not suitable for promoting and applying.
The Chinese invention patent of Patent No. ZL201410175904.8 discloses a kind of sustained release for rice mechanical transplanting and answers
Complex fertilizer, the coated slow-release component of the slow-release compound fertilizer include resin coating composite fertilizer, resin coating diammonium, resin coating chlorine respectively
Change potassium, 2 months resin-bonded grinding wheels, 3 months resin-bonded grinding wheels, although the slow-release compound fertilizer, which has, only needs single-dose application, prolong
Long time for fertilizer realizes the advantages of nutrients release is synchronous with crop nutrient absorption, but each component is resin-coated sustained release
Fertilizer, without quick-acting ingredients, fertilizer cost is excessively high, and available nutrient wretched insufficiency early period, before seriously affecting machine-transplanted rice
Phase tiller influences a mu spike number, seriously affects yield, and because total incapsulation is handled, price is high, lacks production application valency
Value.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of controlled release bulk blended fertilizer resistant to lodging for Direct-seeding Rice, systems
Preparation Method and application, according to the regulation of fertilizer requirement of the Direct-seeding Rice of different growth periods, by Available N-P k particle, different acquisition times
Trace element in anti-floating resin coated urea and coated with resin potash fertilizer and boron zinc-magnesium etc., carries out blending system by a certain percentage
Standby obtained fertilizer, is on the one hand greatly reduced production cost, and on the other hand, available nitrogen, phosphorus, potassium are conducive to point of early period
Tiller and growth substantially increase the effect resistant to lodging and rice quality of rice, meanwhile, fertilizer application frequency is effectively reduced, it is economical real
Favour is conducive to be widely applied, and has actual application value in production.
The present invention solves technical problem and adopts the following technical scheme that：
The present invention relates to a kind of controlled release bulk blended fertilizer resistant to lodging for Direct-seeding Rice, the fertilizer includes following parts by weight
