Potato Summer and Autumn Management

First, the budding period

From late June to mid-July, potatoes entered the budding period, which is also an important period for the simultaneous growth of underground and underground parts. At this point, the potato needs the most water for fertilizer, and strengthening field management during budding period is the key measure for obtaining high yield of potato.

1. After promptly cultivating the potato, it is necessary to strengthen the cultivator, carry out the shallow ramming soil, and cultivate soil with the cultivator.

2. Appropriate top-dressing should apply topdressing nitrogen fertilizer to potato dwarf and yellow weak potato field, and should apply phosphorus and potash fertilizer to the vigorously growing field.

3. Immediately after the potato is budded, it immediately enters the flowering stage and consumes a lot of nutrients. To avoid this inefficient consumption, it should be topped off and the buds should be removed.

4. During the budding stage of the root-spraying fertilizer, the roots should be sprayed in sunny afternoons and sprayed with a mixture of 0.3% potassium dihydrogen phosphate and 0.3% manganese sulfate to make the potato plants dwarf by 1/3 and the leaves become dark green. Enhance photosynthesis and increase the proportion of large potatoes.

5, prevention and treatment of pests and potatoes into the budding period, the growth of the sheltered fields, prone to high humidity environment, resulting in the occurrence of late blight. Once the central diseased plant should be sprayed and prevented, available copper sulfate, chlorothalonil, Rhizoctonia and other fungicides. Potatoes are also susceptible to damage by ladybugs, which can be eliminated by 800-fold spray of omethoate.

Second, the flowering period

From late July to late August, when the potato blossoms, it enters the potato stage, and the water requirement increases. After the plant buds, the underground grape stems begin to swell and enter the peak water demand period. Where the watering conditions occur, they should be carried out during the flowering period. Watering should be done once every 7-10 days to promote the rapid expansion of tuber roots. It should not be poured too late to avoid causing leggy. If there is excessive fishing or rainfall, it should be drained. Where there are no irrigation conditions, the timing of precipitation should be seized, topdressing flowering fertilizers, and flowering fertilizers should be dominated by nitrogen fertilizers.

III. Mature period

From late August to mid-September, potato maturity is the key period for starch accumulation. The most important aspect of field management is to prevent premature senescence, extend plant growth time, and promote dry matter accumulation.

Fourth, harvest

From late September to mid-October, the leaves should turn yellow when the leaves are 2/3 and the plants begin to wither. After harvesting, they were aired in the field for 3-5 days. Soil, sweet potatoes, and mildewed potatoes were removed. Non-damaged and disease-free sweet potatoes were selected for storage. Combined with autumn harvest, the film was removed to prevent soil contamination.
