Abstract

The invention is concerned with the lift-type solid planting method for sweet potato, the characteristic is: spans the traversing suspender between the spaces of the interlacing sweet potato, the height is about 1.0 m to 1.5 m, hangs the cirrus on it. The method is: changes the original growing state of the cirrus to light irradiation all sides solidly; the area coefficient of the sweet potato leaf increases from 1 to 1.8 - 2.0, improves the lighting condition and the ventilation of the plant, and improve the yield and the economic benefit.

Description

The suspending sweet-potato three-dimensional cultivation method

Technical field

The present invention relates to the stereo cultivation method of liana cereal crops, especially a kind of for improving the lift type threedimensional growth method of sweet potato (Ipomoea batatas Lam.) leaf-area coefficient and the bright potato output of increase.

Background technology

The stem of many vine crops originally crawls to grow on the ground, stretches towards horizontal direction.Some crop vegetable variety especially wherein always has the custom of built cultivation.As cowpea, Kidney bean, sponge gourd and the cucumber etc. of greengrocery, grape in the fruit and kiwi fruit etc.Set in brickwork mode has herringbone, frame, rack, hedge wall type, canopy hedge formula and corridor cribbing etc.These crops, all growing at stem branch position usually has tendril, can climb, can the built growth.But some vine crop does not have set in brickwork custom or necessity, and especially cereal crops still do not have set in brickwork example.

Sweet potato is cereal crops, does not have tendril on tendril, and it is relatively poor that its stem rattan climbs ability, from unmanned built, is the nature of crawling to grow in ground always, and output is very limited.

Summary of the invention

The technical assignment of technical problem to be solved by this invention and proposition is to crawl on the ground to grow at cereal crops sweet potato stem, the situation that output is very limited, a kind of sweet potato tendril lift type threedimensional growth method is provided, the potato rattan is grown in space multistory, improve photoenvironment and ventilation condition greatly, reach the purpose of remarkable volume increase.For this reason, the present invention is by the following technical solutions:

The suspending sweet-potato three-dimensional cultivation method, it is characterized in that in the sweet potato planting site one highly being the lateral suspension thing of 1.0m～1.5m (rope or galvanized wire, the bamboo pole etc. fixed with timber as two ends) in the ranks every setting up of 1 row, the potato rattan is hung on it, the potato rattan is stretched, unlikely dropping in solid space on ground.

Described suspending sweet-potato three-dimensional cultivation method when it is characterized in that potato rattan length to 40～60cm, is tied up each plant tip of a branch with the plastic tape bundle, be suspended on side under the lateral suspension thing; Along with the sweet potato tendril constantly grows, suspension height also will constantly raise, and when the long length of potato rattan is spent greater than the lateral suspension object height, the potato rattan directly is suspended on the lateral suspension thing again.

Described suspending sweet-potato three-dimensional cultivation method is characterized in that the top potato rattan with lateral suspension thing both sides corresponding plants, hang on the lateral suspension thing after, be fastened mutually.

The inventive method---suspending sweet-potato three-dimensional cultivation method is not to refer to three-D crop cultivating method in the past.At present, the vertical cultivation of being taked on the agricultural is meant between the interplanting of two or more crop and plants, and is intended to utilize Different Crop property difference and symbiosis phase thereof, and performance space and ground stress effect promote output to improve.As the stereo cultivation method of planting between interplantings such as sweet potato/corn, sweet potato/wheat, sweet potato/capsicum.

The inventive method---suspending sweet-potato three-dimensional cultivation method, obviously different with the sweet potato cultivation method of routine: the inventive method is that potato rattan plant is suspended in the air, early growth period is suspended under the lateral suspension thing, the growth middle and later periods directly is suspended on the lateral suspension thing, and suspension height changes with potato rattan growing height; Cultivation method always is the growth no matter the potato rattan crawls on ground then, and potato rattan growing height does not change.

The inventive method, also cultivation has very big difference with built such as vegetable and fruit:

1. the difference that has or not tendril and climbing ability: sweet potato vine does not have tendril, and it is relatively poor that the stem rattan climbs ability, needs artificial auxiliary the bundle to tie up during proping; Liana vegetables and fruit plant all have tendril usually, and stem rattan climbing ability is stronger, generally need not artificial auxiliary the bundle during built and tie up.

2. the difference of adventive root aspect: in a single day sweet potato vine touches soil, and every joint all very easily grows adventive root; Other vine crops, most no adventive root, or the less or difficult formation adventive root of adventive root.

3. object purpose difference: the inventive method is intended to promote underground nutrition organs by the ground vertical cultivation---bright potato volume increase; Liana vegetable and fruit built is cultivated, and is in order to promote organ of multiplication on the ground---fruit (melon and fruit) growth.

4. the built form is different: the support that the inventive method adopts is a kind of suspended scaffold, and tendril is suspended in the air; Other liana vegetable and fruits adopt frame, herringbone frame, corridor and rack etc., and tendril is not to hang.

5. support service time: the suspending sweet-potato support then service time be about 4 months; The liana vegetables support time was above 6 months; The support of vine fruit then will use for many years.

The inventive method has following advantage:

1. change the sweet potato growth pattern, become and crawl to be grown to aerial three-dimensional growth, be convenient to cultivating and managing, reduce adventive root and form and nutrient consumption;

2. greatly improve plant illumination condition and ventilation situation, about leaf-area coefficient doubles;

3. bright potato per unit area yield increases by 18～46%.

Sweet potato is a kind of liana cereal crops, and its plant is under nature, and along level ground direction growth with stretch, floor space is bigger, and can only simultaneously to be subjected to light, leaf-area coefficient from the top be about 1.Adopt the present invention's lift type threedimensional growth method, the potato rattan is suspended on the lateral suspension thing, three-dimensional growth aloft, illumination condition greatly improves down, ventilation in order, leaf-area coefficient reaches about 2, plant can the four sides solid be subjected to light.Simultaneously, the inventive method can also reduce and avoid the formation of potato rattan adventive root.So can make bright potato output obtain volume increase by a relatively large margin.

Embodiment

Embodiment one

The lift type threedimensional growth of Xu's potato 18 kinds.

1. plant in 0.25 mu of cuttage sweet potato on the 10th seedling in May, 1000 strains.

2. build support late June with rope in the ranks (interlacing) build the lateral suspension thing of 1.2 meters of height, two ends are fixed with timber.

3. tendril is put plant strain growth on the shelf during to 45cm, ties up potato rattan taper with a bundle of plastic tape, and the other end is pricked to tie up and is being suspended on the lateral suspension thing and with the potato rattan below the lateral suspension thing.Along with the tendril growth, improve constantly suspension height.When plant grows to 1.5 meters, again it is directly hung on the lateral suspension thing, artificial auxiliary the bundle tied up.

4. cultivating and managing is with common sweet potato cultivation.

The present embodiment sweet potato produces 1010 kilograms of bright potatos gathering in the crops by the end of October, amounts to 4040 kilograms of per mu yields, and comparison improves 46% according to output.
