Preparation method of kiwifruit pollen

Abstract

The invention discloses a preparation method of kiwifruit pollen, which comprises the following steps: picking kiwifruit big flower buds in a big flower bud stage, carrying out anther removing and drying, and storing dried pollen at an ultralow temperature of -80 DEG C. The preparation method solves the problem that important indexes such as indoor shade drying, lamp drying and solarization temperature are uncontrollable, and is low in price, simple to operate and easy to popularize; and after being stored at -80 DEG C for one year, the pollen still keeps relatively high activity, so that the requirements on production and scientific research can be effectively met. The drying mode is simple and easy to implement and stable and controllable in temperature, can be achieved by individual farmers and is worthy of popularization; and the activity of the pollen stored by according to the scheme reaches 70% or above after 360 days.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a preparation method of kiwi pollen. Background technique [0002] Kiwifruit is a perennial dioecious deciduous vine fruit tree of Actinidiaceae (Actinidiaceae). Under natural conditions, it is mainly pollinated by wind and insect vectors. If it is affected by factors such as weather or insufficient number of male plants in the orchard, the effect of natural pollination will be reduced. Not ideal, artificial assisted pollination is very necessary, and pollen preparation is an indispensable part of artificial assisted pollination. [0003] Common methods of loose powder include indoor drying in the shade, electric lamp drying, sun drying, and drying in a constant temperature oven. The first three methods are uncontrollable in temperature, take the longest time, and cause a large drop in pollen viability. All indicators of the constant temperature drying box are controllable...

AI Technical Summary

Problems solved by technology

[0003] Common loose powder methods include indoor drying in the shade, electric lamp drying, sun drying and drying in a constant temperature drying box. The temperature of the first three is uncontrollable, takes the longest time, and the pollen viability decreases greatly.

All indicators of the constant temperature drying box are controllable, and it takes a long time, but the pollen vigor after drying is between the first three and the self-made electric blanket drying of the present invention. This method is not easy to popularize and use among growers.

[0004] The current kiwi fruit powder patent is to use quicklime to heat and loosen the anthers. The operation is simple and energy-saving, but it is impossible to control important indicators such as powder temperature and time consumption, and the common storage temperature of pollen is -20°C or -40°C.

The pollen stored according to the method of the prior art has a relatively large decline in pollen vigor after one year, generally only 40-50%, which can no longer meet the requirements for pollen vigor in production and scientific research.
