How to cultivate mountain vegetables? Cultivation Techniques of Mountain Vegetables in Yunnan Province

Luliang County, Yunnan Province is rich in mountain resources. The cold weather conditions of the mountain itself, coupled with Luliang County's unique winter and summer cool, moderate temperature climatic conditions, make it suitable for planting summer and autumn and early spring off-season vegetables.

First, the choice of variety and land

Radish is a vegetable that is kept by households in winter. It is resistant to storage and is not easily spoiled during transportation. Therefore, in addition to considering the output, it is also necessary to consider its ability to withstand storage, transportation, pests and diseases. Taking Japanese white radish as an example, the disease-tolerant total and the true winter leap should be the priority varieties. After selecting the radish variety, it is necessary to select suitable land for cultivation. The field should be loose and plowed, rich in organic matter and water, and the soil type is superior to sandy soil or red loam. In addition, it is necessary to pay attention to the fact that radish should not be cultivated adjacent to cruciferous vegetables.

The selection of small green vegetables is preferred to local varieties, and it is necessary to have strong cold resistance, such as green stalks. The land selection for planting small green vegetables should be based on rice, and choose non-polluting, pesticide-free, fertile and flat plots.

Second, nursery

First, soaking seeds promotes germination. After selecting the special vegetable seeds of Luliang County such as radish, small green vegetables, potatoes, and green beans, the selected seeds are exposed to the sun for one or two days. After the seeds are soaked, the seeds are disinfected, and then the disinfected seeds are disinfected. The seeds are soaked at a suitable temperature to allow the seeds to fully absorb the water. When soaking the seeds, the soaking time should be selected according to the thickness of the seed coat. If the seed skin is thick, it needs to be soaked for a while; if the seed skin is thin, it needs to be soaked for a while. The temperature of the soaked seeds is generally 20 to 30 ° C. During the soaking process, it is necessary to germination two or three times a day to allow the seeds to fully obtain oxygen and be uniformly heated. Seeding can be carried out when the seeds are 60% to 70% white.

Third, sowing

In order to achieve high yield of radish, it is necessary to control the sowing date and seeding density reasonably. The radish is usually sown in September each year. The row spacing of radish plants is controlled at 30 cm. The planting density should be controlled at 6 000 ponds/667 m2, and 1 to 3 seeds should be planted per pond. After sowing, check the seedlings and make up the seedlings.

Potatoes are germinated and propagated with their roots, so they should be diced and germinated before planting. Potato seed potatoes should not be too large or too small. They should not be diseased potatoes or rotten potatoes. They should be fully aired before cutting, and then cut into three-dimensional triangles. The buds should have bud eyes, and then they should be immersed in the carbendazim solution and the gibberellin solution respectively. After a certain period of time, they should be taken out and fully aired to achieve the purpose of germination. It is advisable to use sunny days when planting, and the plant spacing is controlled at 25-30 cm. For the sowing of green beans, it is necessary to dig a hole of suitable size, and three or four seeds are planted in the hole.

Fourth, soil preparation and fertilization

If you want to sprout out as soon as possible, you should not only remove the weeds, but also use the tractor to plow the land. This not only makes the land smooth and delicate, but also achieves the depth of cultivated land required for radish cultivation. Fertilize before and after the land is turned over, fertilize the organic fertilizer before the plow, apply urea, compound fertilizer, borax after the plow. The amount of each fertilizer is determined according to the actual situation. After mixing various fertilizers in a certain ratio, it is evenly mixed and then spread evenly in the field.

For the cultivation of potatoes, it is necessary to fully dry the land before winter, and then deep-turn the land after applying the decomposed organic fertilizer, and then apply ternary compound fertilizer, zinc sulfate, boric acid and other fertilizers.

Small green vegetables can be planted several times a year. Before each sowing, the land should be made into regular vegetable dishes. The vegetables should be mixed with fine soil, covered with decomposed farmyard manure, and then watered.

V. Colonization

First, vegetable seedlings should be soiled for planting operations. Seeds are cultivated 7 days before planting, which requires effective measures for ventilation and effective measures to control moisture. Two or three days before planting, the greenhouse does not need to cover the film. The day before planting, the vegetables should have sufficient water, and the corresponding drugs should be used to control pests and diseases, reduce the adverse effects of external factors on the growth of vegetables, and ensure the healthy development of vegetable roots. Second, reasonable close planting. When planting vegetables, we must fully consider their varieties and types, and select the appropriate cultivation methods according to the actual situation. For example, in areas with fertile soil and poor irrigation conditions, planting density can be appropriately reduced. Third, master the depth of planting. If the planting is deep, it is not conducive to the development of the root system, it is easy to appear seedling problem; if the planting is shallow, the phenomenon of vegetable death will occur when the soil is dry. Therefore, a suitable planting depth can promote the survival of vegetables.

6. Field management

6.1 Weeding and soil cover

After the planting operation is completed, the straw needs to be covered on the ground, and the mulch film needs to be covered if conditions permit. The adjustment of soil temperature and humidity is achieved by covering the mulch, thereby promoting the growth and development of vegetables. In the high temperature and dry season, in order to promote the growth of vegetables, it is necessary to appropriately lower the temperature and provide sufficient water for vegetables to avoid the phenomenon of rain erosion and soil compaction, to ensure that the soil in which the vegetables grow is loose and fertile, and to reduce weeds and pests to vegetables. influences.

6.2 Timely scaffolding and pruning

The cultivation of green beans requires scaffolding, and generally chooses a "human" shape or a fence type shelf. After the frame is completed, it needs to be rooted next to it and tied with a plastic rope. When the leaves grow to a certain length, the branches and leaves need to be trimmed, and the old leaves and diseased leaves are removed in time to create a ventilation environment for the growth of the vegetables and increase the fruiting rate.

6.3 Fertilizer management

When applying fertilizer, it is necessary to follow the principle of applying appropriate amount of nitrogen fertilizer and applying phosphorus and potassium fertilizer. At the same time, it is necessary to properly apply top dressing according to the growth of the crop. Drainage should be done after the end of the rainy season to avoid flooding. In order to do a good job of drainage, it is necessary to dig the drainage ditch in advance. Each hillside in the planting area needs to open a drainage ditch from top to bottom. After the drainage ditch is laid, it is necessary to construct a drop zone according to the topographical features to prevent rainwater from affecting the growth of vegetables.

6.4 Strengthen pest control

The prevention and control of vegetable pests and diseases must always adhere to the principle of prevention and supplementation. In the specific prevention and control process, it is necessary to comprehensively apply agricultural, physical, biological, chemical and other methods to achieve effective cooperation of nitrogen, phosphorus and potassium fertilizers, and it is strictly forbidden to use pesticides indiscriminately.

Conclusion
