Abstract
The invention belongs to the technical field of a crop cultivation method, in particular relates to a three-dimensional cultivation method for sweet potatoes and watermelons in a dry land, and aims to solve the problems of irrationality, high labor intensity, low yield, low land utilization rate and the like in the conventional cultivation method for sweet potatoes and watermelons in the dry land. The technical scheme of the invention comprises the following steps of: 1) deeply ploughing the land to the depth of 20-25cm in the middle of October or late October; 2) rowing and ridging according to the conventional method in middle and late March when the moisture content of soil is 65 to 70 percent, applying a nitrophosphate fertilizer in field ditches according to a ratio of 20-25kg/mu, applying a potassium sulfate fertilizer on two sides of the field ditches according to a ratio of 20-25kg/mu, and covering micro-films; 3) planting watermelons in the field ditches in early April according to the row spacing of 40-50cm; and 4) holing and planting sweet potato seedlings on the upper parts of the ridges in late April according to the row spacing of 23-26cm, and watering and covering soil according to the conventional method. The method has the advantages of high yield, low labor intensity, high land utilization rate and the like.
Description
Technical field
The invention belongs to the crop cultivation methods technical field, be specifically related to a kind of nonirrigated farmland sweet potato watermelon stereo cultivation method.
Background technology
Nutrient sweet potato is worth very high, is widely used in health food, exists the sweet potato seedling growth too fast in the existing sweet potato planting process, influence the growth of sweet potato root tuber, cause yield of sweet potato to reduce, at this kind situation, the sweet potato grower often need often turn over seedling, artificially suppresses the growth of rice shoot, guarantees yield of sweet potato; There is the too fast problem of melon seedling growth equally in watermelon in planting process, simultaneously for guaranteeing the pollination of watermelon flower fully, the melon grower need with the growth of watermelon seedling constantly press seedling, make fork, though this method can improve the colored pollination of watermelon, still also has the change melon underproduction of rolling and occurring because of melon seedling.In addition,, need occupy certain space, so need reserve sufficient soil space in sweet potato and the growth of watermelon process, cause the significant wastage of land resources because sweet potato rice shoot and watermelon rice shoot are bigger.
Summary of the invention
The objective of the invention is problems such as unreasonable at existing nonirrigated farmland sweet potato, cultivating watermelon method, that labour intensity big, yield poorly, land utilization rate is low, a kind of output height, labour intensity is little, land utilization rate is high nonirrigated farmland sweet potato watermelon stereo cultivation method are provided.
The present invention addresses the above problem the technical scheme of taking to be:
A kind of nonirrigated farmland sweet potato watermelon stereo cultivation method may further comprise the steps:
1) deep ploughed to 20～25 centimetres in the last ten-days period in mid-October to October in the soil;
2) in the middle ten days and the last ten days in March, soil water content is 65～70% o'clock ridgings that paddle according to a conventional method, and executes nitrophosphate fertilizer according to 20～25 kilograms/mu in furrow, and potassium sulphate fertilizer is executed according to 20～25 kilograms/mu in the furrow both sides, and covers mocromembrane;
3) the first tenday period of a month in April, the spacing in the rows according to 40～50 centimetres in furrow is planted watermelon;
4) last ten-days period in April, roll plantation sweet potato's seedlings in hole on the top on ridge according to 23～26 centimetres spacing in the rows, water according to a conventional method, blinding.
Wherein said soil is red soil soil property or sharp sand soil property soil.
The described diameter that rolls the hole is 1.2～1.5 centimetres, and the degree of depth is 15～20 centimetres.
The present invention compared with prior art has following beneficial effect:
1) the present invention is according to different growth periods priority, the alternately plantation of sweet potato and watermelon, the scientific utilization intergrowth theory, borrow sweet potato piling, the watermelon seedling must be entangled on the sweet potato seedling, both solved that growth of watermelon is in the past pressed seedling, made fork, the hand labor of complexity such as keep down the vines of a creeping plant, prevented the mad length of sweet potato seedling again, saved intertillage, turning over the arduous work of seedling, is the saving of labor's that kills two birds with one stone act;
2) plastic mulching of the present invention has the effect of preserving moisture that heats, the propagation that helps edaphon, making nutrient be made for thing continuously grows and absorbs, according to surveying and determination, quick-acting nitrogen can increase by 30%～50% behind the covering with plastic film, and potassium increases by 10%～20%, phosphorus increases by 20%～30%, plastic mulching simultaneously also can reduce leaching, loss, the volatilization of nutrient, improves the availability of nutrient;
3) the inventive method is taked rational spacing in the rows and film cultivation, keep the moisture and the nutrition in nonirrigated farmland, through test than 2～3 times of every mu of volume increase of epiphragma list kind sweet potato not or watermelon, plant crop yield more than 50%～90% than the list of epiphragma, and the raising land utilization rate of science, the maximization benefit of the low input of the round Realization producer, high production.
