Four unfavorable factors in paddy field management
1. The time for land preparation and field soaking is short, the clods are large, and seedlings are transplanted before the soil is thoroughly soaked; salt removal and alkali washing are incomplete, making salt damage likely and harming seedling growth and development. 2. This year there are many windy days and cloudy days with large temperature differences, so the seedlings cannot be properly ventilated and hardened, which is unfavorable for recovery after transplanting. 3. The masses have a relatively strong fear of water, transplanting in deep water and managing with deep water, which is unfavorable for raising soil temperature after transplanting, early rooting, early seedling growth, and early tillering. 4. Water stored from last winter to this spring is of poor quality, and soil salinity is high, making the rice growing environment unfavorable.

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.

For garlic to yield high, applying four types of fertilizer well is key
Seedling fertilizer: For garlic, after all seedlings have emerged, at the 2-3 leaf stage, apply 40-50 dan of decomposed dilute liquid manure per mu, or 20-25 kg of ammonium bicarbonate. Winter fertilizer: mainly organic fertilizer, applied in shallow furrows 10-15 cm deep between the rows, with 1500-2000 kg of pig and sheep manure and 15-20 kg of ammonium bicarbonate per mu, then cover with soil to prevent fertilizer volatilization; this fertilizer should generally be fully applied before "Winter Solstice." Green-up fertilizer: after Start of Spring, when the rain season begins, apply about 10 kg of urea per mu

Four Major Pests to Focus on Preventing and Controlling in Garlic Cultivation
Garlic has medicinal properties and generally does not contract diseases, so it rarely develops illness, which is already widely known. However, garlic can only suppress the occurrence of certain diseases; it cannot suppress the harm caused by pests. For pests such as aphids, seed maggots, thrips, and leafminers, careful prevention and control should be carried out to ensure garlic quality and improve cultivation benefits: 1. Aphids The aphids that mainly harm garlic include: turnip aphid, cotton aphid, green peach aphid, and mustard aphid, appearing respectively in yellow, green, yellow-green, and some in cherry red. When temperatures are higher, they are more favorable for continued reproduction and

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—

For garlic to be high-yielding, getting these four stages right is key
To make garlic high-quality, high-yielding and early to market, you must get the following four stages right: The sprouting stage: harvested garlic seed remains dormant for a certain period. Therefore, 10 days before planting, the selected garlic seed should be placed in a cool spot and covered with fine sand or loess. Before sowing, soak it in well water for 12 hours. This not only brings germination forward by 2-3 days, but also gives even, sturdy growth. The soil preparation stage: garlic likes moist sandy soil; other loess and clay soils can also be planted as long as they are broken up. The

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:

Detailed Explanation of the Four-Harvest Cultivation Model: Rice, Cotton, Garlic, and Potato
The Gao'an Agricultural Technology Station in Fanchang County, Anhui Province, has promoted a three-dimensional cultivation model of four harvests per year: upland rice, cotton, green garlic, and potato. Per 667 sq m, it yields 213 kg of upland rice, 200.7 kg of seed cotton, 510 kg of green garlic, and 1,480 kg of potato, achieving good economic benefits. The cultivation model is as follows. I. Planting Method Each planting strip is 1 m wide. Cotton is grown in single-row ridges; cotton rows are ridged in single rows 50 cm wide, with 1 m between ridges, and a 50 cm wide bed surface is made between two ridges. Cot-

Four precautions for wheat seed dressing before sowing that you must remember
If the chemical seed dressing before wheat sowing is not operated correctly, it will not only fail to prevent diseases and pests, but may also lead to slow and uneven emergence of wheat, and even affect the normal growth of wheat seedlings. In general, the following 4 points should be noted when dressing wheat seeds with chemicals before sowing: determine the type of pesticide according to the local occurrence of pests and diseases. If the local pest infestation at the wheat seedling stage is very mild and the disease occurrence is severe, only a fungicide seed dressing is needed, and no insecticide is necessary; if pests and diseases occur together, both an insecticide seed dressing and a fungicide seed dressing should be used; if
