How to Improve the Seed-Setting Rate of Sunflowers? A Detailed Guide to the Latest Methods
Sunflowers may be the favorite flower of some people who love eating sunflower seeds. In fact, sunflower seeds can not only be processed into sunflower seeds for eating, but can also be used for oil pressing. It is an economic crop used for both food and industry, and it also has a certain ornamental value. ⟦4 <p>Sunflowers may be the favorite flower of some people who love eating sunflower seeds. In fact, sunflower seeds can not only be processed into sunflower seeds for eating, but can also be used for oil pressing. It is an economic crop used for both food and industry, and it also has a certain ornamental value, so its planting prospects are relatively good. However, many people discover a problem when planting them: the seed-setting rate of sunflowers is relatively low. So how can we improve its seed-setting rate? Details are as follows:</p> <p></p> <p>1. Base fertilizer</p> <p>After sunflowers grow up, the plants become relatively tall with luxuriant roots and leaves, so their fertilizer demand is also relatively large. Before planting, we should apply sufficient base fertilizer, and the base fertilizer should include comprehensive nutrients such as farmyard manure and compound fertilizer. Ensure that there is sufficient nutrient supply for growth throughout the sunflower's growth process. According to the soil fertility, make up for deficiencies and supplement the nutrients lacking in the soil with an appropriate amount in the base fertilizer, so as to improve the seed-setting rate of sunflowers and increase yield.</p> <p></p> <p>2. Density</p> <p>Plan the planting density properly according to differences in variety and planting area. The planting density must be moderate. If it is too sparse, the plants will grow excessively, the sunflower head area will become larger, and thus the nutrients required will increase, leading to more empty seeds. But if planting is too dense, the plants will be short, and the heads will also become smaller, which likewise increases the phenomenon of empty seeds and reduces yield and seed oil content. Therefore, the planting density should be controlled well according to the actual situation and the surrounding environment.</p> <p></p> <p>3. Topdressing</p> <p>As just mentioned, sunflowers have a very large fertilizer demand, so while applying sufficient base fertilizer, we should also carry out appropriate topdressing work, so as to meet the nutritional needs of sunflowers at each stage. The period when sunflowers have the greatest fertilizer demand is during the budding stage and flowering stage. At this time, topdressing is needed. Nitrogen, phosphorus, and potassium fertilizers can be used for topdressing, with the ratio controlled well. However, at the later stage of growth, nitrogen fertilizer should no longer be applied as topdressing, because it may cause sunflowers to stay green and mature late.</p> <p></p> <p>4. Watering</p> <p>Sunflowers are relatively drought-tolerant, but that is because their water storage is sufficient; certain growth stages of sunflowers greatly need water. For example, during the budding stage and flowering stage, the water demand in these two stages may reach half of that during the entire planting period, so the water supply must be ensured. If sufficient water is not provided, then the growth and development of the flower head will be affected to a certain extent. Therefore, we should water appropriately according to factors such as the sunflower's growth stage and soil water content, to promote growth and improve the seed-setting rate.</p> <p></p> <p>5. Diseases</p> <p>Disease prevention and control is very important. Whether disease prevention and control work succeeds or not is directly related to the seed-setting rate. The disease that harms sunflowers the most is sclerotinia, which can directly cause the flower head to rot, severely reducing the seed-setting rate and even causing total crop failure. There is an extremely high incidence rate every year. We need to carry out pesticide prevention according to the occurrence time of sclerotinia. Quintozene can be mixed with fine sandy soil and sprinkled on the soil where sunflowers are planted, then shallow plowing can be done once, and after half a month it can be sprayed again, which can effectively prevent it.</p> <p></p> <p>The above are the methods for improving sunflower seed setting. In fact, what the editor has discussed are some factors that will affect the seed-setting rate. If management is not done properly, these factors will all have a considerable impact on the seed-setting rate. It should be noted that the pesticide for treating sclerotinia needs to be sprayed when the temperature reaches about 20 degrees, the optimal temperature for sclerotium germination, in order to effectively prevent and control it. This article is for reference only, and I hope it can help everyone.</p>
