How to preserve flowers and fruits on goji berry trees? What methods can effectively prevent flower and fruit drop on goji berry trees? We ask netizens to help explainSevere flower and fruit drop is an important reason affecting goji berry yields. Zhongdi Network has compiled several methods for preserving flowers and fruits on goji berry trees, listed in detail below for netizens' reference.
Method 1: Spraying foliar fertilizer on goji berry leaves:
On the basis of applying good base fertilizer, foliar spraying during the flowering and fruiting period can reduce flower and fruit drop. However, different types and ratios of spray fertilizer have different effects on preventing flower and fruit drop. According to experiments: foliar spraying increases the fruit-setting rate by 38% compared with spraying water. The best effect is achieved with a ternary compound fertilizer of nitrogen, phosphorus and potassium, with a ratio of 1:1:1 being optimal; compared with spraying water, it reduces flower and fruit drop by 55%, increases the 1000-fruit weight by 2%-77%, and increases the soluble solids content by 11%.
Method 2: Spraying rare earth solution on goji berry leaves:
According to experiments: spraying a 0.1% concentration of rare earth fertilizer on goji berry leaves can reduce flower and fruit drop by 19%-42%, increase the 1000-fruit weight by 13%, and also promote tree growth, increasing the weight of 100 spring leaves and chlorophyll content, and strengthening phosphorus absorption. For the spraying concentration of rare earth, young trees should use 0.05%-0.10%, and mature trees are best treated with 0.10%-0.15%. If sprayed twice a year, it is best to spray once in mid-June and once in early July. Rare earth can be applied alone or in combination with "Aiduo Shou".
Method 3: Spraying plant growth regulators on goji berry leaves:
Agent 1,a-naphthaleneacetic acid. During the full flowering and fruiting period of goji berries (early June to early July), spraying the tree canopy with a concentration of 15×10-6 to 100×10-6 of a-naphthaleneacetic acid can reduce flower and fruit drop and increase the 1000-fruit weight.
When using it, because the concentration is too low to prepare easily, you can first prepare a high-concentration stock solution, then take a certain amount of stock solution and dilute it with water. For example, dissolve 1 gram of the agent in 1000 milliliters of hot water; each 1 milliliter of the solution then contains 1 milligram of a-naphthaleneacetic acid. If you want to prepare a solution with a concentration of 15×10-6, measure 15 milliliters of stock solution and add 985 milliliters of hot water.
Agent 2, 2,4-D can be used to prevent flower and fruit drop in fruit trees and vegetables and to form seedless fruits. It can also make fruits ripen early and increase yield. During the full flowering and fruiting period of goji berries, spraying the tree canopy with a 15×10-6 to 100×10-6 concentration of 2,4-D aqueous solution can reduce flower and fruit drop and increase the 1000-fruit weight.
Agent 3, Aiduo Shou has effects on plants such as promoting development, advancing flowering, improving quality, and preventing flower and fruit drop. During the flowering and fruiting season of goji berries, spraying the tree canopy with a 0.1%-0.15% concentration of Aiduo Shou can reduce flower and fruit drop by 12%-16% and increase yield by 12%-35%.
