Problems solved by technology

The traditional willow seedlings are sown in the field. Some hybrids emerge as soon as 3 days after sowing, while others only emerge after a week. In addition, there are many microorganisms in the soil, and the seeds are easily infected with diseases and insect pests after sowing. The seed emergence rate is only about 40%. , which is not conducive to the selection of willow breeding and seedling cultivation, and affects the smooth completion of willow hybrid breeding
The method of sowing seedlings in a willow greenhouse, in a sterile environment, by regulating the most suitable temperature and humidity for seed emergence, the emergence rate of willow seeds is greatly improved, and the germination is rapid, and the emergence is uniform, which can ensure that the seedlings of willow hybrid breeding can be obtained. It is an alternative material, which saves the cumbersome process of carefully preparing the bed for sowing. It is easy to operate and has a high survival rate of seedlings. According to literature search, there has been no report in China

Embodiment 1

[0017] (1) Sowing time: From the beginning of April to the end of May in spring, when the capsules of the fruiting branches of the willow tree turn light yellow, and about a quarter of them begin to open the catkins, the seeds are collected in time. After harvesting, use tweezers to gently peel off the catkins that wrap the seeds. get clean seed

[0018] (2) Equipping with sowing soil: put the sowing substrate of each experimental group into the seedling tray and pour water thoroughly, after standing in a cool place for 4 hours, spray and disinfect with 800 times medicinal liquid diluted with 50% carbendazim wettable powder, and set aside; A total of 6 experimental groups were set up for different formulations of seeding substrates. Group I: peat and vermiculite were mixed at a volume ratio of 3:1; Group II: peat and vermiculite were mixed at a volume ratio of 2:1; Group III: Peat and vermiculite were mixed at a volume ratio of 1:1; Group IV: peat and vermiculite were mixed at...

[0026] (1) Sowing time: From the beginning of April to the end of May in spring, when the capsules of the fruiting branches of the willow tree turn light yellow, and about a quarter of them begin to open the catkins, the seeds are collected in time. After harvesting, use tweezers to gently peel off the catkins that wrap the seeds. get clean seed

[0027] (2) Equipped with sowing soil: mix peat and vermiculite evenly at a volume ratio of 3:1, put it into a seedling tray and pour water thoroughly, and after standing in a cool place for 4 hours, dilute 800% with 50% carbendazim wettable powder. Spray and sterilize with the double drug solution, and set aside;

[0028] (3) Sowing: sow the prepared seeds within 30 hours, evenly sow the collected and prepared net seeds into the substrate of step (2), lightly press the seeds to make them closely connected with the substrate, and place them at a temperature of 25°C , on the cultivation frame of a constant temperature greenhouse with ...

Abstract

The invention discloses a willow greenhouse sowing and seedling-raising method. The willow greenhouse sowing and seedling-raising method includes the following steps: (1) seed harvesting and preparing; (2) sowing matrix preparing; (3) sowing; (4) transplanting; (5) seedling management. By means of the willow greenhouse sowing and seedling-raising method, the emergence rate of sowed seeds is higher than 90% and increased by more than 50% compared with a field seedling raising mode, and the time for sprouting and seedling emerging of the sowed seeds is shortened by two thirds compared with field seedling raising. The willow greenhouse sowing and seedling-raising method has the advantages of being low in seedling raising cost, practicable, easy and convenient to operate, high in seedling propagation seedling emergency rate and the like, and has the important application and popularization value in willow crossbreeding and sowing seedling-raising production.

Description

technical field [0001] The invention belongs to the field of crop breeding, and in particular relates to a method for sowing and raising seedlings of willows in a greenhouse. Background technique [0002] Willow (Salix) is a general term for the genus Salicaceae of Salicaceae, a deciduous tree or shrub. It is a native tree species in my country, and it is also one of the earliest recorded artificial cultivation plants with the widest distribution range. There are many varieties and wide distribution of willow tree species, which have extremely high cultural and ornamental value, and play a very important role in afforestation and greening in various parts of our country. [0003] Crossbreeding of willow can recombine the genes of the parents to form various types of hybrid offspring, so as to breed excellent varieties with better traits than the parents through selection, but the vitality of willow seeds is very easy to lose, sowing seedlings is the crossbreeding of willow ...
