斜插法：这是河南省当前大田生产上普遍采用的栽插方法。其特点是薯苗入土的节位分布位置介于水平栽插与直插法之间，单株结薯数比水平插法少、比直插法多，上层节位结薯较大，下层节位结薯较小，结薯大小不太均匀。但是此法抗旱性较好，成活率高，单株结薯少而集中，适宜山岗丘陵地或缺水源的平原旱地采用。此法栽插简单，如适当增加密度，加强肥水管理，即使单株结薯不多但因薯块大仍能获得高产。 

水平栽插法：适合水肥条件较好的www.rixia.cc地块，发挥其结薯多而均匀的优点，可获高产。目前各地大面积高产田多采用此种方法。但其抗旱性较差，如遇高温干旱、土壤瘠薄等不良环境条件，则保苗比较困难，容易出现缺株或小苗，并因结薯数多而得不到充分的营养，导致小薯块增多而产量不高。

直插法：因薯苗入土较深，能利用土壤深层水分，易成活，返苗快，耐旱性较强。适宜山坡干旱、瘠薄及沙土地使用。采用此法成活率高、省工，但要适当增加密度以弥补单株结薯少的缺点，从而提高产量。 

船底形栽法：此法一般选用20厘米-25厘米的薯苗，将头尾翘起如船底形，埋入土中5厘米-7厘米深。因入土节位较多且多数节位接近土表，利于结薯、薯块多。此法适于土壤肥沃、土层深厚、无干旱威胁的地块使用，充分发挥其结薯多的优势获得高产。缺点是薯苗中部入土较深的节位往往结薯少而小，甚至空节不结薯。  

钩形栽插法：此法大致同深斜栽，栽时将苗基部弯成钩状直接压入埂土中，常使基部入土较深，故易成活。苗稍长时可用此法，地上露出10厘米左右的苗身。 

栽插技术：选用壮苗：在苗源充足的情况下应做到用壮苗，剔除弱苗。春薯剪苗前要经过几天炼苗，夏薯选用采苗圃带顶尖的薯苗。因为壮苗返苗快，成活率高，长出的根多、根壮，吸收养分能力强。薯苗进行灭菌处理：主要目的是预防因病害而造成老小苗的发生。

Sweet potato is a kind of crop with high and stable yield. It has the characteristics of wide adaptability, strong resistance, drought and barren, less diseases and insect pests and so on. It is planted in a place with good water and fertilizer conditions. The yield can reach to 2000--3000 kg per mu. In order to give full play to the potential of sweet potato production and to achieve high quality and high yield, we put forward suggestions for high yield cultivation techniques of sweet potato.

I.

Germination and seedling raising is an important part of the whole Off-season Cultivation. The time for raising seedlings is appropriate to move the seed potato into the seedbed nursery in the middle of February. The seedbed is protected by double layer film. The seed potatoes are arranged orderly, covering a layer of fine soil, spreading a layer of plastic film, and then covering a thin layer of the arch to improve the ground temperature of the seedbed. In order to avoid burning fine seedlings on sunny days, we should punch holes on the plastic mulch in time. The seedling bed was sprayed 1 times every 7 days for first months. After L months, 2 water and fertilizer were sprayed every week, and one batch was cut every 7-10 days (when plant height was 15 cm), and 2 water and fertilizer were sprayed every week from first times, and the nutrient supply of the regenerated seedlings was ensured.

Two.

Choose sand soil block, early spring combined with ploughing, Mu fertilizer 2-3 tons, urea 15 kg, phosphate fertilizer 20 kg.

Three.

Film mulching can increase the temperature and moisture content, improve the physical and chemical properties of soil, and increase the temperature difference between day and night in the soil. Planting sweet potatoes can usually be planted with high ridge and double row intercropping, with a whole distance of 60 centimeters, 50 centimeters in cover, 40 cm in small rows, 33 centimeters in interplant interlaced, 4000 trees and high ridges. Moderate, such as too dry during planting, can be planted flat cover to facilitate seedling growth.

Four.

Timely early insertion, reasonable planting: mid April is the seedling planting suitable period, at this time the annual spring temperature is basically stable, planting seedlings after the late frost after the end of the 10 cm temperature up to 15 degrees can start planting, early winter or early in the early years of early spring tillage, planting, ridge and whole furrow. The border zone was wide 50cm. In April, the seedlings were cut and planted in succession according to the seedling rate. The number of tubers was increased by line insertion, increasing the number of potato seedlings to increase the number of tubers. 3500-4000 plants per mu, the plant distance is about 33cm. Planting time should not exceed April 20th, otherwise the harvest time will be delayed, which will affect the transplanting season of continuous cropping late rice.

Early planting is the key to increase yield of sweet potato. Under suitable conditions, the earlier the planting is, the longer the growing period, the longer the growth period, the longer the tuber, the long time of the tuber, the high yield and the good quality, the late growing of the seedlings, the short growth period, the small and low yield of the sweet potato, the low yield of the sweet potato, and the temperature of 10 centimeters above 15 centigrade after the end of the late frost. In order to improve the seedling quality, we should eliminate the "old hard seedlings" and the weakly sick seedlings when planting the seedlings. The best seedlings should be graded and planted in order to balance the growth of the black potato black class disease, which can be used to control the black potato black class disease, and 50 can be used to control the black potato black class disease. The percentage of methyl totozine 1000 times was 2-3 cm in the base, 10 minutes. The sweet potato should strive for shallow planting on the basis of ensuring survival, and the depth of planting is generally 5-6 centimeters, which requires tight soil and consistent depth, so that the leaves are exposed to the ground, the water is not stained with mud, the outcrop of the seedlings should be straight, the seedlings should not be exposed too long to prevent the survival of the big wind and the flinging seedlings.

Four.

The management of 1.|, root and seedling stage was slow, and the period of root setting and slow seedling growth was from 1 months after the emergence of new roots to tuberous roots. When the sweet potato is planted, it is necessary to check seedlings and fill seedlings in time, so as to ensure that the whole seedlings and seedlings should be irrigate slowly in order to survive. Generally, after planting, it should be watered once, and then plowing once every 10-15 days to loosen soil, raise temperature, eliminate weeds, and promote rapid growth of plants to facilitate root formation.

The management of 2.|, branch and tuber stage, 30-40 days after planting, as the temperature rises, the growth of the stems and leaves is quicker, the root of the tuber continues to grow, and the management of water and fertilizer should be strengthened in time. For example, 5-8 catties of urea can be chased after the drought.

The management of 3.|, stems and leaves of long tubers, from the first half of July to the next ten days of 8, the stems and leaves of the long tuber root enlargement, the leaf area coefficient reached the maximum, generally in this period, it is necessary to promote control in the promotion of promoting. This period is in the rainy season, the temperature is high, the plant grows fast, in order to prevent the growth of the plant, it can be used in the field even with the 50PPM's multi effect azole solution in the field, and the leaf surface is covered with the liquid. In this period, the root mass of the underground is rapidly expanding, if the water should be watered, but the amount of water should not be too large. (12) 15 grams of water should be sprayed 7-10 times a day for two times.

After the late 8 month of 8, the stem and leaf growth later, the stem and leaf from the slow growth to the stagnation, the nutrient transfer to the root, the growth center from the ground to the ground, the management should protect the stem and leaf to maintain normal physiological function, and promote the rapid expansion of the root tuber. Management measures to ensure the soil water content, with the maximum water holding capacity of 60 - 70% in the field, such as the long drought and no rain, the soil drought, will make the stem and leaf premature failure affect the formation of carbohydrate. with

红薯的种植方法

1

首先是选择种植容器。番薯是长在地下的，因此块根要求的空间比较大，所以，选择的容器一定要有足够的宽度和深度。深度最好达到50厘米(最低不能低于40厘米），宽度根据种植的薯苗数量决定（单苗种植的容器长宽最好要达到30厘米。种植多根苗的容器，长宽根据株距行距决定，株距一般在20到30厘米，行距一般在30到40厘米，宽叶薯类株行距就大些，小叶薯类株行距就小些）。红薯有一定的耐寒能力，但不耐涝，因此，容器底部一定要打消水孔。

2

接着选培植基质也是很关键的。一般建议选择土壤作为培植基质，如果取土不方便，也可以用锯末之类的填充物，非土壤培植基质对施肥和KXbFBVZ管理要求比较高。番薯喜欢肥沃疏松的土壤，尤其是沙质土壤，这样种植出来的红薯外观好看，因此尽量选树林或是浓密草丛的腐殖质，或是肥效高的沙质土壤。也可以用肥沃安全的淤泥混合细沙来得到沙质土壤。

3

装了土壤后，就要选择合适的摆放位置了。红薯主要成分是淀粉，需要大量的光照才有利于成薯，因此容器一定要摆放在光照充足的天台或是阳台，否则光照不好会不结薯或是结薯不足。此外，还要有足够的空间给薯藤攀爬。

4

接着就是选择种植品种啦，根据自己口味需要来决定。如果只是想摘薯叶吃，则种植食叶品种；根据味道口感，又有甜的、面的之分；此外，近年来还流行颜色养生，比如紫薯富含花青素可以抗癌扛衰老，因此，可以选择紫薯黑薯等。

5

薯苗的选购是很多人的难题，尤其是大城市里。乡村和乡镇集市都是有薯苗售卖的，如果不怕麻烦，可以到乡村市镇购买。但是，对于很多都市人来说，光从薯苗外观也难以分清品种，因此，可以自己培养薯苗，从市场买几个番薯回来，种在花盆里，用不了多久就会长出薯苗来，这样可以买到货真价实的品种。

6

以采食薯叶为主的番薯，春夏秋都可以种植，而采食块根的番薯，则主要分春薯和夏薯。春种则在农历三月到四月间下种，三到四个月后采收；下种则在农历七月到八月下种，三个月后采收。

7

种植前，先要选剪薯苗。薯苗长在20到30厘米之间，至少要有6个芽节。此外，为了刺激长薯，尽量去掉薯苗芽节上的根。

8

在种之前给容器底部装基肥，中上部放几颗复合肥。种的时候薯苗平放，埋入土下5厘米深，露出地面两三个芽节。种后每天早晚浇水一次，坚持一周；也可以把花盆搬到阴凉处，每一两天浇水一次即可。一周后，即可视土壤干湿而浇水。两周后，如果长势弱，可追肥一次；如果长势好，则不用追肥。下种一个月后，施肥一次即可，最后就等着收获啦！

需要注意的是，种来采食块根的番薯，在生长期不可采食薯叶，否则番薯很可能长不大。
