How does jujube increase the fruit setting rate? These three conditions of fruit setting must be understood first.
Jujube is a multi-flowered tree species, and the amount of flowering is far greater than the ability to produce. Under the conditions of better cultivation and management, most of the high-yield trees with higher yields have a flower fruit setting rate of only 1% to 2%. As a result, the average yield of fresh fruit is 10-12 grams, and the yield per hectare is over 22,500 kilograms. Approaching or reaching the limit of high yield of trees. However, due to various reasons, the results of most jujube gardens in China do not reach such a level, and the number of jujube trees is far below this standard and is in a low-yield state. Therefore, improving the fruit yield of jujube has become an important task for jujube trees to achieve high yield and stable yield. Jujube flower takes 3 conditions 1 The tree has a good nutritional status. Nutrition is the basis of jujube flower setting, the tree grows vigorously, and the storage nutrients are sufficient; 2 pollination and fertilization, production of endogenous hormones or artificial spraying of exogenous hormones to stimulate the growth of ovary; 3 Good weather (suitable temperature, air humidity and sufficient light), soil (moisture and mineral nutrients) and other environmental conditions. Tree malnutrition After the flowering period, the fruit drop peak appeared in the northern jujube area from June to early July, and the fruit drop accounted for more than 50% of the total. The main reason for the fruit drop in this period is the lack of nutrition. Because of the large amount of jujube flowers, the differentiation and opening process consumes a large amount of storage nutrients, and the branch growth, flower bud differentiation and flowering of jujube trees occur simultaneously, resulting in an imbalance of nutrient distribution. solution Open armor, that is, ring peeling. By cutting the phloem, the organic nutrients produced by photosynthesis are prevented from being transported to the roots. It satisfies the need for early growth and development of flowering fruit and young fruit, thereby increasing the fruit setting rate and increasing yield. Topping. For the jujube trees of the general planting method, only one topping is performed, and the development branches that do not make the extension branches of the backbone branches and the extension branches of the large branch group, according to the size of the site, leave 2 to 4 base branches to be topped or short. Close planting and ultra-dense cultivation need to be carried out in 2 or 3 times. Provide balanced nutrition. The whole growth period can be sprayed three times with Eumet or Euphoric 1000-1500 times foliar surface, every 7-10 days; the first fruit period is 1000-1500 times for Eumerica or 1500 times for Euphorbia. Boron fertilizer, calcium fertilizer). Poor hormone and variety pollination Jujube fruit is caused by the formation of the detachment of the fruit stalk, which is related to endogenous hormones such as auxin IAA, abscisic acid ABA and cytokinin; most of the jujube varieties can be self-pollinated, but some varieties have pollen development. If it is not good, the fertilization is not complete, causing the embryo to abort and fall. solution Spraying gibberellin at the flowering stage; spraying naphthalene acetic acid in the young fruit stage. During the physiological fruit drop period, exogenous hormones such as triacontanol are sprayed, and at the same time, it is 1000-1500 times mixed with Emmett or Umejia, and 1000 times higher than Euphorbia. Water imbalance The flowering period of jujube is very sensitive to soil moisture. The jujube flowering period in the north of China is in the hot dry season. When it encounters drought, it will cause curling, coke, and bokeh, which will seriously affect the fruit setting. 7 to 10 days before flowering or a large number of young fruit after flowering at the end of the flowering stage. If the soil is dry, it should be watered in time. The purpose of spraying water during the jujube period is to increase the air humidity and solve the inhibitory effect of low-humidity drying on the germination of jujube pollen. solution Small areas of water spray should be carried out in the evening or in the early morning when the temperature is low and the air humidity is high. To improve the effect of water spray to promote fruit setting, it is now possible to take a large area of ​​sprinkler irrigation, and the dampness time can be maintained for more than 10 hours, the effect is very obvious.
