It's time for the northern sunshine roses to repair the spikes, the time to expand the fruit, the fruit thinning workers in Yunnan are full of schedules, many rows can't be arranged, and friends who can't wait to start thinning their own fruits, in fact, fruit thinning is not difficult, it is difficult to know what kind of spike type is better? How to combine beauty and high yield? Which is more pleasing to the public, the navel eye or the teardrop shape?
First of all, it is said that there are three types of spikes in the sunshine rose on the market,
The first type is to leave five or six layers of spike tips
Comments
This should be a beautiful art spike type, and the sunshine rose that was dozens or even more than a hundred pounds large was such a spike type. Single panicle 40--45 grains, 15--16 grams, 1.2--1.5 kg of panicle weight.
doubt
The fruit grain is small and there is no yield, the fruit grain is too big to squeeze in panic, why should I choose? To be productive, either the panicles are more, or the ears are larger, or the grains are larger.
1. The spikes need to be dense, the small frame type is barely OK, the space of the large frame type is difficult to set 4,000 shoots per acre, and the leaf shading also creates difficulties for disease prevention.
2. Spike seems to be a solution, but the spike tip is so large that it can only leave a few more layers, and then we analyze the advantages and disadvantages of leaving several more layers.
3. The size of the grain is mainly subject to the short claws at the tip of the panicle, the room for extension is not large, when the single grain weighs more than 20 grams, the fruit grains will be crowded together, increasing the risk of fruit splitting. At the same time, the fruit stems at the tip of the spike are thin, the nutrient transport is slow, and it is difficult to cultivate large fruit grains.
Key points
The key point of the spike tip is to use the spike tip as a reference at the time of seedless treatment, starting from the spike tip full of flowers and ending 24 hours after the spike tip petals fall out.
The second type is to leave seven or eight layers of spike tips
This panicle type resembles a corn ear and mostly leaves 8 layers of fruit. Single panicle about 60 grains, most of the fruit grains above the large (18--20 grams), below small (15--16 grams), single panicle weight of 2 pounds up and down, per acre 2500--3000 strings, to solve the yield problem.
Sunshine roses generally bloom from top to bottom, and if the spike type is too long, the flowering period will be uneven, which makes the timing of seedless treatment difficult to choose. The upper part of the reference spike is upturned and stiff, and the reference tip of the panicle has a nucleus or hollow in the upper part.
1. In actual field operations, most of them use the tip of the spike as a reference, so the seedless rate will become the entry point for vendors to reduce prices.
2. The middle and upper part of this panicle type is long, if the single layer is really compact and beautiful, I am afraid that if two or three fruit grains are damaged in the same position, the fruit grains on the side will be troublesome if they cannot be squeezed. Bugs, scissors, daily fever, diseases...
3. The upper and lower stalks of this panicle are thick and thin, and the upper part of the fruit grains get more nutrients, so they are sweeter, larger and earlier ripening, and the grains at the tip of the ears are small and late ripening. If you sell the spike tip early, the taste will be light, and if you delay the sale, the upper part will have slight rust spots.
The key point of the corn ear is the timing of picking, the radish is easy to say when it is fast and does not wash the mud, and it is more difficult to speak when it comes to the buyer's market. At present, it can only please the channel, and it is really not possible to cut off the parts that people do not like (rusty fruit, pitted fruit, hollow fruit, unripe fruit) when selling.
The third kind, pinch the head and tail to leave the middle
This type of spike we call him a big fat spike, most of them leave 6 layers of fruit. Single panicle about 60 grains, most of the fruit grains 18--20 grams, single panicle weight of more than 2 pounds, 2500--3000 strings per acre.
1. It is indeed not as beautiful as the tip of the ear, and it is really difficult to open the mouth if the big fat man spike type wants to be worth tens or hundreds.
2. When dealing with seedless, because the flowering period is uneven, it is difficult to choose the treatment time, and the treatment is early and the spike tip is stiff, and the upper secondary panicle is grained late
The key point is still seedless treatment, generally most of the flowering time into the ground treatment, if the spike tip is not blooming, then hand off the spike tip, if the spike tip has been flowered, then retain the spike tip.
In other words, while the seedless treatment is carried out, the part that does not flower is cut off, and there will not be too many zombie fruits.
