The release fruit, also known as fenugreek, is one of the famous tropical fruits. Its appearance is not beautiful, but its taste is excellent. At the same time, it also has the economic value of processing. There are a lot of areas in the south of China are planted. In the planting management of the release fruit, fertilization technology can be said to be the most important. So how to fertilize the release fruit? Today, let’s learn about it.
A、The release of the fruit of the young tree fertilization points
Fertilization of young trees and fruit fertilization is not the same. In general, in the release of young trees before planting, you need to apply sufficient fertilizer to protect the growth of young trees. Basal fertilizer is usually applied in February to March before planting. Fertilizer application can be done simultaneously with trenching. First, dig a planting trench on the planting site at a certain spacing between plants and rows. Then, base fertilizer is applied in the trench and mulched once more.
This is to avoid direct contact between the young roots of the release fruit and the fertilizer, which eventually causes root burn. It also facilitates the absorption of the root system. Fertilizer is recommended to choose green manure or well-rotted farmyard manure, usually about 10-20 kg per plant. In addition, 1 kg of phosphate fertilizer can be applied to ensure the growth of young plants. In addition, the young trees of release fruits are weak in disease resistance, so in addition to applying sufficient base fertilizer, it is also necessary to add appropriate lime. It can reduce the occurrence of diseases. For young trees need several fertilization. Generally speaking, in each new sprouting when the appropriate fertilizer.
B、The fertilization of adult release fruit trees
For the adult release of fruit trees, also to ensure that there is sufficient intake of fertilizer. This will not only ensure the growth of tree growth, but also promote the hanging fruit. General fertilizer can choose to spring or autumn, that is, in February or October. We can decide the amount of basal fertilizer according to the growth, age and yield of the adult trees of the release fruit. Generally the release of fruit tree age and high yield of the tree, need to increase the amount of fertilizer application. For example, for every 100 pounds of fruit produced, you need to consume about 20 pounds of high-quality manure. This can play the effect of the base fertilizer.
For the adult release of the fruit tree fertilizer, generally need to chase fertilizer 5-6 times a year. Roughly divided into flowering fertilizer, fruit fertilizer, fruit picking fertilizer. One of the main purpose of the flowering fertilizer is to promote flowering and flower preservation, the time is about between February and March. Since the release fruit flower has a high requirement for phosphorus and potassium fertilizers, we recommend choosing a compound fertilizer with uniform nutrients. At present, the compound fertilizer that used more in the market comes from Nagric. Fertilization requires a specific period, and we generally fertilize after the flowers have faded. Again, we recommend the application of a compound fertilizer. The last fertilization is at the fruit picking period, in late September. We usually apply 5-10 kg of farmyard manure per plant, which will promote the recovery of the tree.
C、The release of fruit irrigation management
The budding period of release fruit, young fruit expansion period, fruit rapid expansion period, post-harvest recovery period and dormant period need water. We need to look at the specific situation in a timely and appropriate irrigation. It can ensure the fruit set rate, large fruit rate, excellent fruit rate, root system and tree strength recovery. Irrigation is mainly by hole and furrow irrigation. If there is not enough water, the plant will have poor growth, untidy budding, a large number of young fruits falling off, poor fruit development and a large increase in the rate of fruit cracking. However, release fruits are also most afraid of waterlogging, and even a short period of waterlogging can lead to the same results as water deficiency. And it can also cause root rot, which can lead to plant death. Therefore, we need to do a good job of drainage in a timely manner.
D、The release of the fruit of the flower and fruit management
The release of fruit with pistils first, the stigma tolerance time is short. Flower discernment completely open, it takes about 48 hours. The flower disc opens fully just before the petals split. At the same time, the filaments elongate rapidly, followed by anther dehiscence and release of pollen. Stigma tolerance not only completely lost at the time of anther dehiscence, but also partially lost in the short period before anther dehiscence. Therefore, hand pollination requires that the flowers open halfway and the anthers do not split. The method of artificial pollination involves using a brush to dip pollen from a flower with fully opened discs and anthers naturally splitting. Then, pollinated on the half-open style of the flower disc, dipped in a pollen pollination 2 to 3 flowers.
2、Thinning flowers and fruits
Usually, we remove all the first flowers that open in early May. Focus on leaving the flowers that bloom from mid-May to June. After the formation of young fruit, to timely thinning of deformed fruit, disease and insects fruit and too much too dense small fruit. Each fruiting branch generally leave a fruit. After leaving the first season fruit, after the end of the physiological fruit drop in the first half of July, should also be thinned out part of the fruit on the tips of healthy branches. Can ensure that there are enough mother branch spitting summer tips.
Release fruit growth period is long, often to experience a variety of temperature changes and harassment of diseases and insects and birds. If not bagging will affect the commerciality of the fruit. Bagging time is appropriate when the fruit thumb size, bagging before spraying a fungicide and insecticide.
4、Harvest at the right time
Release the fruit of live seedlings in the plant after 3 to 4 years that results. After the sixth year into the fruit of the peak, the fruit in late August to September maturity. When the fruits not soft ripe crack, fruit color slightly turn green and yellow, the skin slightly attacked white, you can cut off with stalk harvest. After harvesting, it needs to ripen 3 to 5 days before consumption, not hard ripe fruit does not have commercial value because it cannot ripen normally.
