Description
Technical field
The utility model belongs to the sand field of planting, is specifically related to the composite sand pattern of farming that a kind of utilization can be directly used in the porous plantation sand of water conservation, fertilizer conservation of plantation and nutrient planting sand and self-defence ventilative planting container.
Background technology
The desertization phenomenon is a kind of natural phenomena, is because earth dry zone moves the climatic variation that produces and causes some areas desertization.And, along with global climate reach day by day badly that the soil that population fast growth brings is excessively developed and cultivated, herding, cause global desertization process more and more faster, can plant the arable land and day by day reduce, Agricultural production ability continuous decrease.Especially for the such country of having a large population in a small area of China, the negative effect that brings but growing desertization process causes the minimizing of agricultural and planting soil is fatal.
But the day by day minimizing of agricultural and planting soil, directly cause grain and crop yield to descend, this mainly is because in the present agricultural grain product and vegetables and fruits plant husbandry, it is main that what rely on is in the adhesion of soil and cohesion water conservation, fertilizer-preserving ability, to be applied to moisture and the fertilizer maintenance of Plants and play effectiveness, the natural grains of sand after the desertization are then because the surface is comparatively smooth and grains of sand adhesive capacity each other is relatively poor and so that it does not have the ability of water conservation, fertilizer conservation, and can't be used for the usefulness of plantation.
At present, agronomists are for the day by day improvement of desertization, except be devoted to develop desert planting, concentrate on and in the desert, carry out antiseepage or windproof processing, weaken sandy soil migrations, promote the survival rate of desert always, also be devoted to develop the plantation sand that water conservation, fertilizer conservation function are arranged that some can be applicable to daily agricultural planting, can improve agricultural soil reduces the predicament that brings day by day on the one hand with expectation, also helps to improve simultaneously the utilization ratio of the sand that day by day gathers.

Cultivate after 15 days, get the soil specimen in the planting container of embodiment 5-8 and Comparative Examples 2, and it is cleared up be liquid sample, adopt the ion chromatography instrument to detect phosphorus content remaining in it, measure simultaneously the growing state of plant seedlings in each container, detect simultaneously the remaining composition of the liquid that oozes out the flowerpot outside that each embodiment collects, comparing result sees the following form.
| Sequence number | Phosphorus content (g/L) in the container | Ooze out composition phosphorus content (g/L) | Fruit plant height (cm) |

From embodiment 1 and Comparative Examples 1 and embodiment 5 and Comparative Examples 2 data can find out, when using identical existing porose planting container plantation, the porous plantation sand that mixing described in the utility model is used and nutrient planting sand facies are for existing soil plantation, the performance of its fertilizer conservation quite even increase, the plant growth situation is also slightly good, prove that porous plantation sand described in the utility model and nutrient planting sand have suitable with soil at least ability for the plantation fertilizer conservation, are conducive to plant growth; Can find out in the correction data from embodiment 2 and embodiment 3 and embodiment 5 and embodiment 6, with water-tight vessel as plantation with being fertilizer when running off, use the plant growth performance boost of planting container plantation of waterproof and breathable described in the utility model more, the simultaneously fertilizer amount consumption in the container also exceeds a lot, as seen permeability is to the importance of plant growth, and have the preferably planting container of permeability and the growth that described sand pattern of farming helps plant described in the utility model are described; From embodiment 2 and embodiment 4, and the data of embodiment 6 and embodiment 8 can find out, the plant growth performance of arranging the sand pattern of farming of laying with porous plantation layer of sand and nutrient planting layer of sand mode interlayer is better, and the utilization ratio of fertilizer is also higher.
Obviously, above-described embodiment only is for example clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And the apparent variation of being extended out thus or change still are among the protection domain of the invention.
