Abstract
The present invention discloses controlled-release fertilizer bag specially for tree. Soluble quick-acting chemical fertilizer is packed into impermeable bag of polymer film and the bag has holes made in certain amount of size and number to regulate the fertilizer releasing speed. The fertilizer may be one single fertilizer or mixed nutritive fertilizer and may also be composite multifunctional fertilizer with mixed plant growth regulator and/or pesticide. The present invention is simple and practicable, and the bag is made preferably with degradable film to avoid pollution to soil.
Description
Technical field
The present invention relates to fertilizing bag, be specifically related to a kind of trees special-purpose control-release fertilizer pocket.
Background technology
What existing controlled availability fertilizer had is difficult to artificial control as rate of release such as urea-formaldehyde, sulfur coated urea, ammonium magnesium phosphates, and the polyene fat coated carbamide price as Japan that has is too high again, and large-area applications is restricted.
Summary of the invention
The objective of the invention is to: a kind of trees special-purpose control-release fertilizer pocket is provided, realizes that fertilizer control release is long-acting, reduce farming originally.
Technical solution of the present invention is: the quick-acting fertilizer packagings of solubility are gone in the fluid-tight bag to make bag with fertilizer, and this bag with fertilizer is a polymeric film pouch, with the bag Wrapped fertilizer, and quantity and the big or small rate of release of regulating fertilizer by punching on the bag film; Described release and release control fertilizer can be a kind of straight fertilizer, also can be the full nutritious fertilizer that multiple fertilizer mixes, and can also be the complex function fertilizer such as able to prevent and eliminate diseases and pests that add plant growth regulator or other agricultural chemicals.
Used coated fertilizer bag can be common plastic film bag or similar containers, also can be the membranaceous lapping bag of degradable.
The simple for production easy row of this bag with fertilizer, but the composition and the rate of release regulated at will of the interior nutrient of bag; Because the planting density of trees is low, the individual plant fertilizing amount is big, and again methods of spreading manuer in holes that adopt make that this coat fertilizer pocket is feasible economically more; In addition, trees fertilising point is clear and definite, and it is few to execute number of spots, and the plastic film that residues in the soil can take out when applying fertilizer next time, if adopt degradable films to make parcel bag, just can not pollute soil.
Embodiment
Embodiment 1: with urea 200g, MAP 100g, potassium sulphate 100g mixing, getting 300g is sub-packed in 3 plastic sacks, every bag of 100g, with diameter 1mm pin, difference acanthopore 5,10,15, promptly form the control-release long-acting bag with fertilizer of different rate of release, cut-off footpath 10cm, 4 of the plastic barrels of high 30cm, end opening nylon wire tying, the first wet fine sand of shop height 10cm, each one bag of release and release control fertilizer putting into different rate of release respectively have one directly to put unpacked mixed fertilizer 100g and compare in addition, repave the fine sand of 10cm height, at room temperature, in the 15th, 30 days, 45 days, 60 days, 90 days, every added water 600ml and divides three drip washing, collection filtrate, survey nitrogen with Kjeldahl method respectively, the yellow colorimetric method of vanadium surveys phosphorus and flame luminosity is surveyed potassium, calculates the drip washing total nutrient content and accounts for the percentage that drops into nutrient, the results are shown in Table 1.
Table 1 controlled release fertilizer nutrient rate of release is measured

If fertilizer such as employing urea, phosphorus ammonium, potassium sulphate are mixed with the full nutrition quick-acting fertilizer of 15-15-15 ratio, about 1300 yuan per ton of fertilizer cost.By per 100 gram mixed fertilizer is a pouch, 10,000 bags in fertilizer per ton, the size of plastic sack is long 12cm, wide 8cm, thickness is 0.01mm, material is a polyethylene, the heavy 0.18-0.020g of individual plastic bag, and fertilizer per ton weighs 1.8-2.0kg with plastic sack, about 20 yuan of cost, add packing, seal etc., 80 yuan of per ton costs, adding up to increases by 100 yuan of costs.Adopt this technology to realize the long-acting cost that increases of fertilizer control release, only account for 8% of fertilizer cost.With the fast growth poplar is example, every mu of 25 strains of planting trees, and the 3-4 growing poplar, every strain 4 caves of applying fertilizer, 1 bag in every cave, fertilizer per ton can be used for 100 mu of ground 2500 strain willows, directly uses than common equivalent chemical fertilizer with control-release long-acting fertilizer of the present invention, and every mu only increases by 1 yuan of cost.
Embodiment 2: with red triangle brand 45% granular compound fertilizer of commercially available Nan Hua company, by the amount of the every bag of 100g thickness 0.01mm that packs into, long 12cm, in the polyvinyl chloride plastic pocket of wide 8cm, evenly punch 13 with the 1mm pin on the plastic sack, make the control-release long-acting bag with fertilizer, consistent business willow 6 strains in 3 years of choosing growth, be divided into two groups, 4 bags of release and release control fertilizers are executed in one group of every strain, and another organizes contrast, divide 4 caves with kind equivalent common fertilizer, fertilizer placement is apart from trunk 50cm place, east, the west, south, each cave, north, degree of depth 20cm, fertilising date: March 11, measure the above 1.3 meters diameters in the height of tree and ground during fertilising, get side shoot measuring blade nitrogen content May 25 and September 15, November 20 was measured the height of tree and the diameter of a cross-section of a tree trunk 1.3 meters above the ground, the results are shown in Table 2, use the fertile bag of controlled release and keep the leaf nutrition level higher in the long time, the tree body increases fast.
