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.

Detailed Explanation of Four Key Points for Winter Cultivation and Management of Oyster Mushrooms
1) Light should be strong rather than weak. Light is not only an important way to raise the shed temperature in winter, but also an important means to increase yield and improve mushroom quality. Light intensity and duration should be determined according to the insulation performance of the mushroom shed and weather conditions. If the insulation performance of the mushroom shed is good and the nighttime temperature can be maintained above 5°C, then the straw mats on the shed roof can be uncovered early and covered late, extending the daytime light duration as much as possible; otherwise, the daytime light duration in the mushroom shed should be correspondingly shortened. As for weather conditions, when the temperature is below 5°C, on sunny and cloudy days, under the condition of ensuring a shed temperature of 5°C

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:

How to carry out field management of licorice? Four key points to master
Cultivation: Licorice seedlings grow slowly, and weeds have a relatively large impact on them. Cultivation should be combined with timely removal of weeds, with weeding 2-3 times in the same year. After the plants grow larger, weeds become fewer. Pay attention to pulling out weeds, and avoid hoeing the soil, so as not to damage new shoots sprouting from the rhizome. Topdressing: Licorice belongs to the legume family, and its root nodules have nitrogen-fixing ability, so nitrogen fertilizer is generally not applied, and phosphate fertilizer is mainly used for topdressing. After the aboveground parts of licorice wither in late autumn, 2000 kg of decomposed farmyard manure can be applied per mu to cover the ground, so as to increase ground temperature and soil fertility. Thinning: For direct-seeded seedlings of the same year, when they have 2-3 true

Four key points to ensure fish fatten up in autumn
A fishing proverb says: In summer they grow shells, in autumn they grow flesh. When autumn turns cool, it is the peak season for fish growth, and the following four points must be well managed: 1. Manage feeding and fertilizing well. Generally, from September to November, both the amount of fertilizer applied and the amount of feed given should account for about 30% of the total for the whole year. When applying organic fertilizer, apply small amounts multiple times to avoid excessive fertilization causing pond fish to gasp at the surface; when applying inorganic fertilizer, use 5-7.5 kg of ammonium bicarbonate per mu, or 2.5-3.5 kg of urea. After "White Dew," grass resources gradually

How to care for roses? Master these four key points
The rose is a plant that loves sunlight very much; if there is not enough light, it is very difficult to get it to bloom every month. To make roses bloom year-round, you must grasp the following four keys. (1) Sunlight must be sufficient: the place where roses are planted must be both well ventilated and able to receive more than half a day of sunlight; this is the primary condition for them to bloom in profusion. (2) They must be pruned often: even if the sunlight conditions are good, roses will not grow well if they are not pruned for a long time. The pruning method is: after December each year, when the rose leaves fall, prune once; after May, each time a round of flowers finishes blooming, cut away 2/3 or 1/2 of the branch that has bloomed, so there will be more chances for new flower buds to regenerate. The wounds caused by pruning should be sealed promptly with healing and antiseptic membrane to prevent the wounds from drying and cracking and from damage by pests and diseases, and to promote the rapid growth of callus tissue.

What are the four key points to get right for fish farming at the start of spring?
1. Fertilization: In early spring, when the pond water temperature stabilizes at 8°C-10°C, start applying supplemental fertilizer to cultivate natural food organisms in the water. The amount of fertilizer should be determined according to the fertility of the water quality and the quality of the fertilizer. Generally, apply 60-90 kg of human excrement and urine per mu; or 100-150 kg of livestock manure. If chemical fertilizer is used, follow a nitrogen-to-phosphorus-to-potassium ratio of 1:1:0.5. When applying, first crush and mix with water, then splash evenly over the whole pond, with a total amount of 3-7 kg per mu, and an interval of 5-10 days between each application. Keep the pond water quality yellow-brown or yellow-green, with a transparency of 30 cm

How to manage greenhouse apricots? Master these four technical points
1. Fertilizer and water management. Apply base fertilizer every autumn. The base fertilizer is mainly organic fertilizer such as livestock manure, compost, and cake fertilizer, appropriately mixed with some nitrogen, phosphorus, and potassium fertilizers. After covering with plastic film, no more topdressing is applied; after fruit set and during the hard-core stage, spray once with 0.3% urea plus 0.2% compound micronutrient fertilizer and 0.3% monopotassium phosphate. Install drip irrigation pipes in the greenhouse and water reasonably according to soil moisture. Do not water too much, so as to avoid excessive growth of new shoots and cause physiological fruit drop. 2. Training and pruning. For "Y"-shaped training, mainly retain lateral branches (main branch branching angle about 70 degrees
