Four key points to master in rice fertilization
First, pay attention to applying sufficient organic fertilizer. Organic fertilizer contains various nutrients, can improve soil aeration and its characteristics of absorbing fertilizer and retaining water, promote robust growth of rice plants, and achieve high yield and good quality. Organic fertilizer is mainly used as base fertilizer, applying 30-40 loads of decomposed farmyard manure per mu, or 30-40 kg of cake fertilizer, and 40-50 loads of human and livestock manure can also be applied after plowing and before flooding. Second, pay attention to controlling nitrogen fertilizer. Excessive application of nitrogen fertilizer to rice will not only cause an increase in ineffective tillering, greening, lodging, and intensified pests and diseases, leading to more empty and shriveled grains, a decline in the seed-setting rate, and affecting rice yield.

Four Key Points for High-Yield Cultivation of Spring Potatoes
Last October, many people in this village sowed potatoes, but a frost hit and they were all frozen to death. I sowed potatoes twice myself, at the end of January and in February this year; although they were not frozen to death, they only grew foliage and produced few and small tubers, and many had their centers hollowed out by termites. In addition, he used continuous cropping. The reader asks when it is more suitable to sow potatoes, and how to prevent frost damage and termites. For spring potatoes to be high-yielding, the main attention should be paid to the following four aspects: Pay attention to timely sowing. If spring potatoes are sown too early, the seedlings are prone to frost damage and death after emergence.

Four key points for rice management in August: seize the critical period to ensure a bumper harvest
1. Apply rice field herbicides at the right time. To eliminate weeds in the rice field, herbicides should be applied at the right time. This saves labor (no need for intercultivation) and money (about 2 yuan per mu for chemicals), and also resolves the conflict of weeds competing with rice seedlings for fertilizer and light, which restricts the normal growth and development of rice seedlings. The specific method is: 5—7 days after transplanting, apply per mu 20 grams of Caocaolong or 60—100 grams of Dingbian mixed with urea (combined with topdressing), fine sand, or dry mud powder 30—40 jin, broadcast after the dew has dried, and maintain a shallow water layer for 4—

How to grow spring-planted garlic for high yields? Master these four cultivation points
Garlic planted in spring and harvested in summer has a shorter seedling stage and less nutrient accumulation, so both yield and quality are inferior to autumn-planted garlic. To improve the yield and quality of spring-planted garlic, you must select good varieties and focus on management. The key is to do well in the following four aspects: 1. Choose suitable varieties: spring-planted garlic takes about 100 days from planting to harvest, and the whole growth period is very short, so choose short-growing-period purple-skin garlic as seed garlic. 2. Apply heavy base fertilizer: before sowing, while preparing the land, apply 3000 kg of high-quality human and livestock manure or barnyard manure per mu, 15:

A detailed guide to four-season spinach cultivation techniques: master the key points for growing year-round
1. Sowing time and varieties. Autumn spinach is the main crop in spinach production, generally sown from August to September, but sowing can also be advanced to July or delayed to early October; after sowing, it can be harvested in batches in 30-40 d (days). Variety selection requirements are not strict, but for early-autumn spinach it is best to choose early-maturing varieties that are more heat-tolerant and fast-growing, such as Litou spinach, Huabo...

For high peanut yields, manage these four key points well in the late stage
The late growth stage of peanuts runs from when 50% of the plants show filled pods to when most pods mature and are harvested. The growth characteristics of this period are: vegetative growth gradually declines and stops, the pods gradually fill out and become plump, and the increase in pod weight generally accounts for 500%-70% of the total pod weight, making it the main period for pod yield formation. Field management technical measures for this period...

Sweet potato fertilization has its subtleties: keep these four points in mind
1. Harvest at the right time and avoid mechanical damage. Summer sweet potatoes should be fully harvested around Frost's Descent, and autumn sweet potatoes before the Start of Winter. Choose a sunny day for harvesting, and when digging the tubers, minimize or avoid causing wounds. 2. Select healthy tubers carefully to ensure safe storage in the cellar. Before the sweet potatoes go into the cellar, select them carefully, discard diseased, damaged and rotten tubers, let the moisture dry off, then store...

When is the best time to harvest sweet potatoes? Master the four key points of timely harvesting
Many farmers believe that growing sweet potatoes does not require fertilization, but this is actually a misconception. Only by mastering the correct fertilization methods can sweet potatoes be grown with high quality and high yield. Look at the seedling condition: during the branching and tuber-setting stage, the underground root network forms, the tubers begin to swell, and the ability to absorb fertilizer is strong. At this time, the sweet potato leaf area increases and photosynthetic efficiency rises...
