Abstract
The invention discloses a slow-release fertilizer for watermelons in dry sandy field. The slow-release fertilizer comprises the following compositions in percentage by weight: 20 percent of urea, 60 percent of calcium superphosphate, 19.4 percent of potassium sulfate, and 0.6 percent of sustained release drug; the sustained release drug is prepared by mixing nitrogen inhibitor and phosphorous activating agent according to weight ratio of 3:1; and the nitrogen inhibitor is prepared by mixing nitrification inhibitor and urease inhibitor according to a weight ratio of 1:0.3. The slow-release fertilizer for watermelons in dry sandy field has the advantages of being simple to apply, capable of conducting application at one time, low in production cost, and high in fertilizer utilization rate, and increasing the yield of watermelons.
Description
Technical field
The present invention relates to a kind of chemical fertilizer, particularly, relate to a kind of non-irrigated sandy land watermelon slow-release fertilizer.
Background technology
The drought sandy land is the field that the face of land has covered 7-20cm thickness gravel or cobble folder coarse sand; Be NORTHWEST CHINA arid, unique, the traditional drought resisting tillage method in semiarid zone; Be to create the non-irrigated agro-farming of coming out during numerous working people long-term farming short of rain in arid and saline and alkaline barren land is put into practice to make form, one of the covering of dependent territory earth and soil and water conservation method.
China's sandy land is mainly concentrated and is distributed in rainfall Middle Gansu Province on the low side, and the some areas in Ningxia, Qinghai and Xinjiang.Show that through practice and research the more native field of sandy land has the evaporation of minimizing and runoff, improves the soil moisture, moisturizes and infiltrate, stop the effect of soil erosion and soil secondary salinization.
In recent years, the development along with sandy land melon dish industry has obtained remarkable economical, ecology and social benefit.And sandy land is because its singularity, and in long-term cultivation process, fertilising difficulty is the subject matter of puzzlement sandy land production always; Conventional fertilizer application not only labour intensity is big, and production cost is high, and utilization rate of fertilizer is low; And be prone to cause sand to mix, cause the sandy land ecological functions to descend, shorten the working life of sandy land.And the more common fertilising of slow-release fertilizer is compared; Have and can be used as disposable full dose base manure and use; Reduce fertilizer application frequency and recruitment, crop is to nutrient absorbing efficient advantages of higher, and the administering long-lasting slow-release fertilizer can reduce because of topdressing to the number of times that stirs of sandy land on sandy land; Therefore the working life of corresponding prolongation sandy land, has the dual function of economic benefit and ecological benefits.
Summary of the invention
The technical problem that the present invention will solve is to overcome existing defective, and a kind of slow-release fertilizer that is exclusively used in non-irrigated sandy land watermelon is provided, and it has fertilising simple (can disposablely apply), production cost is low, utilization rate of fertilizer is high, The yield of watermelon increases advantage.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of non-irrigated sandy land watermelon slow-release fertilizer, form by following component in percentage by weight:
Urea 20%, superphosphate of lime 60%, vitriolate of tartar 19.4%, sustained release drug 0.6%;
Said sustained release drug is mixed by nitrogen suppressor factor and the phosphorus activating agent weight ratio according to 3:1;
Said nitrogen suppressor factor is mixed by nitrification inhibitor and the urease inhibitor weight ratio according to 1:0.3.
Particularly, said nitrification inhibitor is dihydro-amine (DCD); Said urease inhibitor is N-NBPT (NBPT); Said phosphorus activating agent is a humic acids.
Particularly, said urea contains N amount>=46%, and superphosphate of lime contains P
2O
5Amount>=12%, vitriolate of tartar contains K
2O amount>=50%.
The present invention has following beneficial effect:
(1) can be used as that base manure is disposable to apply; The special-purpose fertile fertilizer efficiency period of this drought sandy land watermelon long-acting slow-release reached about 120 days; Rumble is disposable to apply with applying fertilizer before the watermelon sowing, to can be used as base manure, need not manuring late, has reduced fertilizer application frequency; Reduced labour intensity and farm work and caused sand blended probability, working life that can corresponding prolongation sand.
(2) obviously improve The yield of watermelon; Improve quality of watermelon: compare with the conventional fertilizer application that waits nutrient; It is special-purpose fertile to use non-irrigated sandy land watermelon long-acting slow-release, can make the sandy land The yield of watermelon improve 20-34%, and single melon is brought up again high 12-20%; And significantly reduce watermelon center and peripheral sugar gradient and effective acidity, nitrate content reduction about 20%, Vitamin C content increases 8-10%.
(3) plant recovery of nutrient obviously improves: the special-purpose fertile nutrient proportioning characteristics of this non-irrigated sandy land watermelon long-acting slow-release are that nitrogen content is moderate, phosphorus content is the highest, potassium content is lower; The fertility characteristics of " the few nitrogen, lack phosphorus, rich potassium " that is just shown with sandy land district soil adapts; And added sustained release drug is that collection nitrogen suppressor factor and phosphorus activating agent are the compound fertilizer sustained release drug of one, and it is less that the release of nutrient is influenced by soil moisture, influenced by the soil moisture; In watermelon growing in earlier stage; Crop is less to the nutrient demand amount, and ground temperature is also lower, so nutrient discharges also slower; The watermelon growing middle and later periods, the crop fertilizer requirement is bigger, and ground temperature is also higher; Therefore nutrient discharges and accelerates, and this just adapts with the fertile characteristic of need of non-irrigated sandy land watermelon, and then has improved fertilizer utilization ratio; Compare with conventional fertilizer application, nitrogen, phosphorus, potassium utilization rate improve about 20%, 5% and 23% respectively.
(4) preparation technology is simple, raw material sources are abundant: the present invention be with various raw materials by a certain percentage mixing granulation get final product, preparation technology is very simple, cost is lower, non-pollution discharge in the course of processing; This long-acting slow-release fertilizer using on non-irrigated sandy land watermelon both improved the economic benefit of sandy land watermelon, reduced the number of times that stirs to sandy land again, prolonged the working life of sandy land accordingly, has the dual function of economic benefit and ecological benefits.
