Embodiment 1

[0010] The fertilization method of embodiment 1 foliage fertilizer

[0011] 1. Preparation of foliar fertilizer The spraying concentration of foliar fertilizer should be within a certain concentration range. The speed and quantity of nutrients entering the leaves will increase with the increase of solution concentration, but fertilizer damage will easily occur if the concentration is too high, especially FeSO 4 , MnSO 4 , ammonium molybdate and other trace element fertilizers, the critical range of crop nutrition from deficiency to excess is very narrow, and should be strictly controlled; there are also potassium fertilizers containing growth regulators, which should also be sprayed strictly according to the concentration requirements to prevent regulation. Improperly causing harm. Different crops have different concentration requirements for different fertilizers; so the fertilizer ratio is determined as potassium fertilizer: ZnCl 2 : FeSO 4 :MnSO 4 : The weight ratio of ...

Embodiment 2

[0017] Several different foliar fertilization contrast experiments of embodiment 2

[0018] Choose a large field where Polygonum multiflorum is planted, and there is no difference in soil quality, humidity, and light, and uniform base fertilizer and the same topdressing fertilizer are applied.

[0019] Weigh 20g of humic acid, KH 2 PO 4 30g, ZnCl 2 30g, FeSO 4 60g, MnSO 4 6g, ammonium molybdate 15g, urea 300g, dissolve with 15L water to obtain foliar fertilizer spraying liquid I;

[0020] Weigh KH 2 PO 4 150g is diluted with 15L water to obtain the contrast foliar fertilizer spraying liquid II;

[0021] Weigh 150g of swollenin, KH 2 PO 4 150 g was diluted with 15 L of water to obtain the contrast foliar fertilizer spray solution III.

[0022] In the field, three rows were randomly selected as a group to spray the above-mentioned foliar fertilizer spray liquid, and the fertilization method was the same as in Example 1.

[0023] When receiving the goods, 3 plots ...

Abstract

The invention discloses a foliar fertilizer for polygonum multiflorum planting. According to a formula, the foliar fertilizer comprises humic acid, KH2PO4, ZnCl2, FeSO4, MnSO4, ammonium molybdate and a nitrogen fertilizer in a weight ratio of 1-4:1-5:1-5:10-8:3-1:1-3:10-60. The yield of polygonum multiflorum to which the foliar fertilizer is applied is obviously higher than that of the polygonum multiflorum to which the foliar fertilizer is not applied or other foliar fertilizers with a common formula are applied.

Description

technical field [0001] The invention relates to a foliar fertilizer, in particular to a foliar fertilizer used for planting Polygonum multiflorum. technical background [0002] In addition to absorbing nutrients through the root system, crops can also absorb nutrients from their leaves. Foliar fertilization is also called root topdressing or foliar spraying. This fertilization is a fertilization method often used in production. The prominent feature of foliar spray fertilizer is that it is highly targeted, which can make the nutrient absorption and operation fast, avoid the fixation of some nutrients by the soil, improve the nutrient utilization rate, and the amount of fertilizer is small, suitable for the application of micro-fertilizers, and the effect of increasing production is remarkable. Especially when the soil environment is poor, too much water or drought and low humidity conditions, the soil is too acidic or too alkaline and other factors cause the absorption of th...
