Embodiment 1

[0041] Example 1: Screening test of spraying period of milk vetch compound nutrient preparation

[0042] 1. Experimental design

[0043] In 2017, in the late wintering period (March 6, T1), greening period (March 15, T2), budding period (March 23, T3), early flowering period (March 28, T4) and 5 days after flowering (April 2, T5), the compound nutrient preparation (Na 2 B 4 o 7 2000mg / Kg, ammonium molybdate 400mg / Kg, KH 2 PO 3 2000mg / Kg, PP 333 300mg / Kg, 6-BA 10mg / Kg, BR 0.04mg / Kg, AOS 20mg / Kg), with spraying clear water as a control; the amount of spray is based on the formation of a layer of water mist on the surface of the leaves but no dripping. The area of ​​each treatment plot is 20 m 2 , repeat 3 times.

[0045] From the analysis of the yield components, there was no significant difference in the thousand-grain weight between the...

Embodiment 2

[0050] Embodiment 2: Concentration screening test of milk vetch compound nutrient preparation

[0051] 1. Experimental design

[0052] Combined with soil preparation before sowing, 103.45 kg of urea (N 46.4%) and superphosphate (P 2 o 5 12%) 562.5kg, potassium chloride (K 2 O 60%) 112.5 kg.

[0053] The test material was sown on September 28, 2019 (Xinzi No. 1), and the sowing rate was 22.5 kg / hm 2 , When sowing, mix the seeds with fine sand and spread them. The cultivation and management of the experimental field is the same as that of the general high-yielding field.

[0054] During the budding period (March 17), the following solutions were sprayed on the leaves respectively. The amount of spraying was based on the fact that a layer of water mist was formed on the surface of the leaves but did not drip. The area of ​​each treatment plot was 20 m 2 , repeated 3 times:

[0055] Control: clear water (CK)

[0056] Treatment 1 (low-concentration compound nutrient prepara...

Embodiment 3

[0064] Example 3: Comparative verification test of the application of milk vetch compound nutritional preparations

[0065] 1. Experimental design

[0066] Combined with soil preparation before sowing, 103.45 kg of urea (N 46.4%) and superphosphate (P 2 o 5 12%) 562.5kg, potassium chloride (K 2 O 60%) 112.5 kg.

[0067] The two-year test material was sown on September 28 (Xinzi No. 1), and the sowing rate was 22.5 kg / hm 2 , When sowing, mix the seeds with fine sand and spread them. The cultivation and management of the experimental field is the same as that of the general high-yielding field.

[0068] During the budding period (March 17), the following solutions were sprayed on the leaves respectively. The amount of spraying was based on the fact that a layer of water mist was formed on the surface of the leaves but did not drip. The area of ​​each treatment plot was 20 m 2 , repeated 3 times:

Abstract

The invention relates to a compound nutrition preparation for Astragalus sinicus as well as preparation and application thereof, and aims to solve the technical problem that high yield and stable yield are difficult to obtain due to the lack of targeted growth regulation and control means of Astragalus sinicus at present. The compound nutrition preparation contains effective components such as sodium borate, ammonium molybdate, monopotassium phosphate, paclobutrazol, 6-benzylamino adenine, brassinolide, sodium alginate oligosaccharide and the like. By spraying the compound nutrition preparation in the Astragalus sinicus cultivation process, and a high Astragalus sinicus seed yield and a high biological yield can be obtained. The compound nutrition preparation is low in preparation cost, simple and convenient to apply and stable in effect.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to milk vetch compound nutrient preparation and its preparation and application. Background technique [0002] Milk Vetch ( Astragalus sinicus L. ) also known as safflower grass, rocking, grass seeds, etc., is a plant of the genus Astragalus in the leguminous family. It is one of the traditional green manure crops in China. It can improve soil physical and chemical properties, increase the number and diversity of soil microorganisms, and improve soil fertility. With the extensive application of green manure crops in the field of agricultural production, milk vetch seed production has become an important link in the development of green manure production. At present, the investment in basic research on milk vetch seed production is insufficient, and the research on high-yield theory and supporting technology of milk vetch seeds is relatively weak, resulting in low and unsta...
