Potatoes, a high-yielding and adaptable crop, are not only resilient but also resistant to drought and infertile infestation. Cultivated in areas with high water fertility, the acreage of spring potatoes can be up to 2,000 to 3,000 kg. However, due to differences in the natural environment and cultivation techniques, the level of the individual cassava is highly uneven. In order to realize the full potential of the increased production of potatoes and to achieve the goal of high quality production, we have prepared technical proposals for high-yielding cultivation of potatoes。
I. Brewer beds
In anti-season planting, seedlings are a key step. In order to ensure that the seeding of potatoes is successful, we suggest that it be moved to protected nursery beds around mid-february. Slender beds should be protected with double film to maintain high temperatures. When the potato is grown in an organized form, it covers a layer of fine soil, which is then covered by a sheet of film. This would not only increase the temperature of the earth, but would also facilitate the growth of seeding potatoes。
In the process of breeding, care needs to be taken to fill the membrane with holes in a timely manner in order to avoid high-temperature fever. In addition, regular water spraying is required to maintain the humidity of seed beds. During the first month of the nursery, water is sprayed every seven days; after a month, twice a week, water is sprayed with fat and new high-fat membranes are added to prevent infection and ensure healthy growth of the seedlings. When the seedling is up to 15 cm, it is cut every 7 to 10 days, while water is sprayed twice a week, increasing the concentration as appropriate to ensure the nutrient supply for regenerative seedlings。
Ii. Equipment of between benefits
In the early spring, soil flaring and sandy plots are selected for tillage. Each acre should be applied to two to three tons of farm fertilizer, together with 15 kg of urea and 20 kg of phosphorus fertilizer, to provide sufficient nutrients for the growth of the potato。
Membrane cover technology
The membrane cover not only has a significant warming corrosive effect, it can also effectively improve the physico-chemical nature of the soil and further increase the temperature differential of the soil day and night. In cassava cultivation, planting is usually carried out in the form of high-swidth covered double-bar staggered planting, ensuring a total distance of 60 cm, coverage of 50 cm, 40 cm between small lines, staggered between strains and a distance of about 33 cm, with approximately 4,000 seedlings kept per acre. At the same time, it is adjusted to the actual situation, and in the event of drought during planting, the option is to flatten the seedlings in order to facilitate healthy growth。
Iv. Early planting in due course
Early and timely cultivation is essential in the cultivation of potatoes. In mid-april, planting began when early spring temperatures returned warm and stable, and when the night frost ended at temperatures above 15°c. The tan soil is tilled early and the tan soil is soared at the time of planting, with a width of 50 cm. Based on the rate of seedling production in the nursery bed, the planting of seedlings was continued in mid-april, using a linear approach to increase the number of seedlings in soil, thereby increasing the number of potatoes. Between 3,500 and 4,000 units per acre have been inserted at a distance of about 33 cm. It is important to note that it is not advisable for the implants to go beyond 20 april in order not to affect the cutting season of late rice。
Early planting in due course can prolong the growth cycle of the sweet potatoes, making the potatoes early and large, expanding for long periods of time and ultimately improving yields and quality. Late planting can lead to a long-term reduction in life and a decline in production and quality. Therefore, planting should begin as early as possible under suitable conditions of temperature above 15°c at the end of the nightfall. In order to ensure the quality of planting, “old hard seedlings” and weak seedlings should be eliminated, seedlings should be selected for planting, and attention should be paid to grade planting to promote balanced growth. At the same time, 50 per cent of methyl tobzin can be immersed in seedlings at 2 to 3 inches and for 10 minutes to combat red potato black class disease. In the case of planting, it should be ensured that the ground is exposed to the blades and that the water is not muddled to ensure high levels of activity of the potatoes。
V. Professional management
Field management is an indispensable link in the cultivation of potatoes. Starting with planting, it is necessary to pay close attention to the growth of potatoes and to take appropriate management measures. First, it is neither too dry nor too wet to ensure that the soil remains suitable for the growth of the red potato root system. Second, weeding should be done on a regular basis in order to reduce the competition between weed and the potato nutrients. In addition, fattening needs to be timely, depending on the growth of the potatoes, to meet the nutritional requirements for their growth. Care should also be taken to combat pests and diseases in order to ensure healthy growth and high quality of potatoes. These elaborate field management measures can effectively improve the yield and quality of potatoes。
Management of the root seed phase
This phase lasts for about a month, starting with a new root after the cultivation of the potato, until the root is formed. At this stage, seedlings need to be identified in a timely manner to ensure the growth of the whole seedling. In the event of severe drought, the water should be poured in time to facilitate the life of the potato. At the same time, pine fields are cultivated every 10-15 days in order to preserve the proper moisture of the soil and to eliminate competition for weeds. In addition, new high-fat membranes can be sprayed in due course to facilitate the rapid growth and root formation of plants。
Management of the cleavage stage
Roots continue to form and expand during the 30-40 days after planting, as temperatures rise and leaves grow more rapidly. At this stage, the management of hydrofertilizers should be strengthened to ensure healthy growth of potatoes. In the event of a dry weather, 5-8 kg of urea can be followed by water. At the same time, care should be taken to keep the soil wet by planting pine pores。
The management of the long-spreaded roots of the leaves
During the period between the first half of july and the second half of august, the leaves grew strongly and the roots expanded rapidly. At this stage, there is a need to promote controlled and managed management strategies. Care should be taken to prevent the growing of plants, which can be sprayed with multi-effect apricot and tirex. At the same time, in the event of drought, water needs to be poured in time to maintain soil moisture. In addition, it can be sprayed with inflatables to boost the expansion of chips。
Management of the rooting of the leaf decline
After mid-month, the leaves of the late growth of the sweet potatoes declined and nutrients began to shift to the roots. At this stage, it is necessary to protect the leaves from normal physiological functions and to promote the rapid expansion of the roots. This can be achieved through measures such as ensuring soil water content, timely watering, and leaf fertilizing. At the same time, care should be taken to prevent premature decay and to extend the light co-operation of leaves to increase production。
Picking the top and cracking the fat
Capturing can be done during the growth of the sweet potatoes to curb the growth of the penis and promote the expansion of the root blocks, while cracks can be treated for fattening to improve yields and quality. These measures can be undertaken at the right time to improve the production and quality of potatoes。
Getting it in time
Potato harvests generally begin at 15°c and are performed at temperatures above 10°c or above 12°c to ensure the high quality of potatoes. The harvesting process should be completed before and after the cold rise to ensure the safe storage and processing of potatoes。
