Prevention Methods for Sweet Potato Cellar Rot and Storage Management Techniques
The biggest problem during sweet potato storage is cellar rot. Once cellar rot occurs, it may at best reduce the quality of the sweet potatoes, and at worst cause all the sweet potatoes in the cellar to rot, resulting in varying degrees of loss. Sweet potato cellar rot is mostly caused by physiological diseases and infectious diseases. Physiological diseases mainly

Detailed Explanation of Foliar Fertilization Methods for Sweet Potato Cultivation
During its growth, the sweet potato can be divided into three types: weak seedlings, strong seedlings, and vigorous seedlings. Foliar fertilization must be carried out in a targeted manner according to the different growth appearances, in order to promote robust vines and high tuber yields. For weak seedlings in such fields, 0.5-1 kg of urea, 1-1.

Summary and Sharing of Experience in Double-Season Sweet Potato Cultivation
I. Variety Selection: Choose virus-free early-maturing varieties, which can be harvested just over 3 months after planting, allowing off-season marketing and yielding considerable economic benefits. Early-maturing varieties can include Japanese Yellow Sweet Potato, Yushu 10, Sushu 8, etc. These early-maturing varieties have vines 50-70 cm long and are suitable for close planting.

Common Abnormal Phenomena During Rice Seed Germination and Remedial Measures
During the germination of rice seeds, abnormal phenomena such as dead seeds, slime production, sprout scorching, and uneven roots and sprouts occur. In fact, these conditions are mostly caused by poor management; as long as the cause is identified and reasonable remedial measures are taken promptly, losses can be reduced and strong seedlings can be cultivated. 1. Many dead seeds.

The correct method for soaking and germinating hybrid rice seeds
Now is precisely the main spring production season. A small number of farmers, due to improper operation during the soaking and germination process, have encountered problems such as seeds turning sour and smelly and poor sprouting. Therefore, when soaking and germinating seeds, attention should be paid to: 1. Sun-drying the seeds: one week before soaking, choose a sunny day and sun-dry the seeds for 3-4 hours

What are the key management points during the grain-filling stage of rice?
The grain-filling stage of rice is the critical period that determines yield. Field management should aim to nourish the roots and protect the leaves, prevent premature senescence, improve photosynthetic efficiency, promote grain filling, and increase the seed-setting rate and grain weight. 1. Supplemental application of grain fertilizer: apply grain fertilizer according to the seedlings, the field, and the weather. Apply it when the leaf color is on the yellowish side and the flag leaf is short and small; do not apply it when the leaf color is deep green and the flag leaf is large and plump. Apply it to lean fields, not to fertile fields; apply it when there are many sunny days, not when there are many cloudy and rainy days. Generally, it is appropriate to apply 2-3 kg of urea per mu at the booting stage.

Field Management Techniques for Rice During the Jointing and Panicle Elongation Stage
Rice jointing begins around the peak tillering stage and internode elongation does not stop until several days after heading; in production, this period is called the jointing and panicle elongation stage. The field management goals during the jointing and panicle elongation stage are: on the basis of preserving tillers and increasing panicles, promote strong stems and large panicles, and prevent excessive vegetative growth

Key Technical Points for Field Management of Rice During the Green-Returning and Tillering Stage
The green-returning and tillering stage of rice refers to the period from transplanting to the time before jointing and booting. This period is important for determining the number of panicles and laying the foundation for panicle and grain development. The main goal of field management is to promote good root development, rapid green-returning, and early tillering, and to form sufficiently strong
