核桃仁不饱是什么原因呢

The phenomenon of walnut kernels has been confused by planters, especially last year due to the continuous high temperature days, the sunburn phenomenon has occurred seriously, resulting in the harvest of the fruit is difficult to sell or low-cost hands. Now entering the grain filling stage of walnuts, from the perspective of the development of walnut fruit, the key to improving the fullness of nuts is to grasp the key period of nutrient accumulation in the early stage of July to the end of August, and prevent the disease from happening. Several steps should be taken as follows:

Fertilization should be timely and sufficient.

Walnut is a high-yield oil and wood, which requires a large amount of fertilizer and requires a small amount of water. After entering the fruit-bearing period, it is necessary to use the fertilizer as a first-class task.

It takes about 130 days for the walnut to mature from flowering to fruit ripening. From the end of April to the beginning of June, about 30 to 35 days is the long-term fruit speed. During this period, the volume and weight of the fruit increase rapidly, and the volume reaches 90% of maturity and the weight reaches 70%. In this period, the nutrient is insufficient and photosynthesis is used. Less product will result in a smaller fruit, which is the determining period of fruit size. From the beginning of June to the beginning of July, it is the hard core period of fruit. In this period, the fruit size is basically fixed, and nutrients are rapidly accumulated. In this period, if the light is insufficient, the core shell will be unrealized and the phenomenon of Luren will appear. From the beginning of July to the end of August, about 50 to 55 days is the rapid conversion period of fats and oils. During this period, the rapid increase of fruit fat, the rapid enrichment of seed kernels, the rapid growth of weight, and the rapid decline of water content are the key periods for the accumulation of nutrients in walnut kernels. From the end of August to the beginning of September, about 15 to 20 days is the fruit ripening period. The fruit weight in this period increases slightly, and the oil content still increases. Therefore, in the annual cycle, under the premise of applying the base fertilizer, it is necessary to combine the phenological period with flexible and timely fertilizer application. Phosphorus and potassium fertilizer should be added after June. Insufficient nutrient accumulation seriously affects the quality of walnut fruit.

In July, pest control should be done well

xx为解决核桃仁不理想的问题,从病虫害防治措施来看,主要是预防病虫害,其次是叶片害虫,以保证树木的健康,提高光合作用效率。 7月应重点防治黑点,褐斑病和核桃炭疽病,有效防止黑核桃的发生,提高核桃果实的商品率。在分配过程中添加M-JFN原粉或金福牛可以显着改善叶子功能并帮助李子丰满。

白白露应用之前和之后都要收获。

核桃的收获将导致不足或更多的大麦,导致产量减少;收获晚期的核仁涂层将是黄色和黑色,难以出售,一般白色露水前后,有3%~5%的绿色皮肤裂缝在树上可以采摘。过早收获将不可避免地减少产量,并且核仁很小并且通常具有空的或半核,这将大大降低商品率。核桃产区的大多数人,由于害怕丢失或其他原因,核桃采摘一般是早期,有一种“避免”核桃的习惯,这更适合核桃10至15天的收获期早。但是,产品质量降低,影响销售价格,大大降低了总回报。事实上,这不值得。

需要匹配高温抗晒树

核桃晒伤是一种在炎热季节容易引起的细菌性疾病。同时,在阴雨天气的情况下,燃烧部分通常是腐生孢子。解决晒伤最有效的方法是匹配树的形状,并尽量避免水果暴露在阳光下。中农乐推出的短圆形天然圆头形状是最科学,易结果,易于生产,易于管理,抗晒伤能力强,减少了大麦的机会,与其他树形相比具有明显的优势,并可以积极推广。
